SIEMENS is offering the compact and versatile geared motor solutions that can be optimally integrated into the drive train. Always both precise and powerful. More flexibility, more power, a more standard approach – these are the expectations of the sector, especially in conveyor technology.
SIMOGEAR gear motor delivers performance from 0.09 kW up to 55 kW. It can achieve a gear unit torque up to 19.500 Nm with helical, parallel shaft, helical bevel and worm geared gear units, additional types and sizes. Due to accordance to the current measures, SIMOGEAR is compatible to many other suppliers of geared motors. The new series of SIMOGEAR geared motors is 1:1 compatible to the general standard in the market, and can therefore be simply integrated into existing or new machines and systems.

2. SIMOGEAR reluctance geared motor

Reluctance geared motors boast with extremely high energy efficiency, especially in partial load. The motor efficiency is comparable to IE4. They are very easy to service thanks to the synchronous-reluctance solution. They can reach precise speed even without encoder. It is possible to achieve high permanent overload in high speed range. The synchronous reluctance solution allows for application in many different fields and with the major technical benefits compared to a standard asynchronous solution. The SIMOGEAR reluctance geared motor is particularly suited to conveyor technology and general machinery systems where the application with high energy efficiency is demanded. Together with the right converter, the portfolio is very extensive. The system is typically used for rollers, chains and belt conveyors within the baggage and cargo handling facilities at airports. It also fits within warehouses and distribution logistics and in postal and packaging. It is commonly used in hoisting gears, scissor lift tables and monorail conveyors as well as in rollers, chains, belts and skids used in the automotive industry.

3. Gears with motor adapter

In addition to versions with integrated motors, the SIMOGEAR series is also available with motor adapters for the use of various motors. Due to the specially designed traction group the whole variety of Siemens motors can be mounted. That is true for asynchronous as well as synchronous motors. With the new developed short coupling adapters the right geared motor are provided suitable for every application. SIMOGEAR adapter currently include:
IEC motor adapters - there are two possibilities for the mounting of IEC standard motors. We suggest the short adapter K4 for universal use and the coupling adapter K2 for more sophisticated use. The adapters can be mounted on all types of SIMOGEAR and are in accordance with the dimensions of the IEC standard flange (B5).
NEMA motor adapters - there are two possibilities for the mounting of NEMA standard motors. We suggest the short adapter K5 for universal use and the coupling adapter K3 for more sophisticated use. The adapters can be mounted on all types of SIMOGEAR.
Motor adapters for servomotors - the adapters for servomotors are based on three versions. The first one is the new KS adapter available for SIMOTICS S-1FL6, S-1FK2, S-1FK7, S-1FT7, M-1PH8 and is extensively widening the SIEMENS drive system portfolio for the servomotors. Other two are the KQ adapter which designed for the SIEMENS SIMOTICS S-1FK7 and SIMOTICS S-1FT7 synchronous servomotors. The third type is K8 adapter available for SIEMENS SIMOTICS M-1PH8 asynchronous servomotors.

4. SIMOGEAR geared motors with motor-integrated frequency converters

SIMOGEAR geared motors with SINAMICS G110M motor-integrated frequency converters provide the perfect solution to any conveyor-related challenge. The system is easy to install, features a fast start-up, and is extremely user friendly. Thanks to Safety Integrated, the Safe Torque Off (STO) safety function can be used with any SINAMICS G110M with no additional external components. The compact device, available in two sizes (FSA, FSB), is space saving and offers flexible application fields. In addition, it is integrated into the TIA Portal – the intuitive engineering framework from Siemens – which allows efficient integration into a superordinate SIMATIC controller.

5. Servo geared motor

When developing SIMOTICS S-1FG1 servo geared motors, special emphasis was placed on the optimum coordination with the SINAMICS S120 drive systems. Motors, converters and commissioning tools are optimally coordinated and harmonized with one another. The system can be quickly commissioned as a result of the electronic type plate and the fact that the motors are connected via the DRIVE-CLiQ system interface. Prefabricated MOTION-CONNECT signal and power cables mean that the components can be simply and perfectly connected with one another.

SIMOGEAR Reluctance Geared Motor

The new SIMOGEAR synchronous-reluctance drive system consists of SIMOGEAR standard gear units, SIMOTICS synchronous-reluctance motors and SINAMICS frequency converters. With this solution, Siemens is widening the SIMOGEAR geared motors portfolio by newly combining the gearbox with the reluctance motor from SIMOTICS as a completely new offering for the customer. By combining the aforementioned products the customer benefits especially from the efficiency class compared to IE4, which scores with higher efficiency and lower losses, especially in a partial load than to comparable asynchronous motors. Highly energy efficient, the motor heats up less and provides a high operation reability due to its excellent thermal behavior. Because of that high service factors are achieved. This solution also boasts with high dynamics thanks to the motor's lower moment of inertia and optimized control. Commissioning is established quickly and easily by entering the motor code into the converter. The constant torque-speed characteristics up to the rated speed make an external fan redundant. In the drive system, all components are perfectly coordinated together.

 1) Flexible
The KS adapter is the preffered solution available to connect to various servomotors within the different functional performance and price segments, from standard ones through midrange level to high-end types.
With its compactness and even shorter design compared to the KQ adapter it reduces the total size of the whole package.
The KS adapter ensures a smooth handling solution for high-precision servo applications.

2) Combinable
With the KS adapter is possible to combine five types of SIMOTICS servomotors and four types of SIMOGEAR gear units.
Further cost savings due to optimized spare part stock - one flexible adapter that can be used with different servomotors.
User-friendly installation is offered by a simple solution made from the connection of the KS adapter assembled together with the gearbox, servomotor and on the top combined with a perfectly matching frequency converter.

3) Optimized
The KS adapter offers back-lash free coupling without feather key which grants better accuration and positioning.
Fast and simple mounting and removal of the motor on the gearbox reduces the standstill times and costs.
With only one adapter Siemens reduces the possible variants of offered adapters for servomotors and makes the result even more simple and easy to use for the customer.

Siemens Geared Motor Models

Gear motors are generally used in low-speed high-torque transmission equipment, which is achieved by transmitting the motor or other high-speed transmission equipment to the output shaft gear through the reducer.

1. Under the volume, the minimum diameter can be 3.4mm.
2. High transmission rate: single-stage greater than 96.5%, double-stage greater than 93%, three-stage greater than 90%.
3. Smooth operation and low noise.
4. Light weight, long service life and high carrying capacity.
5. Customized parameters, power and wide application range.

Gear motors are widely used in smart homes, automotive drives, robot drives, e-commerce logistics warehouses, precision instruments, industrial automation equipment, electronic products, precision mechanical equipment, etc.

Selection of gear motor:
To determine the model of a gear motor, you need to do the following:
1. Determine the operating speed of the machine and calculate the reduction ratio of the gear reduction motor according to this speed;
2. Calculate the torque of the load, select the output of the gear reducer motor according to this torque (refer to the "output torque table" provided by the manufacturer of the gear reducer motor), and determine the model of the gear reducer motor;
3. Determine the additional functions of the gear reduction motor, such as power-off brake, power-on brake, frequency conversion, shrink frame, shell material, etc.

Structure and characteristics:
The load torque of the DC gear motor has a direct relationship with the speed and current. The speed decreases linearly with the increase of the load, and the current increases linearly. When selecting specifications, you should try to work near its maximum efficiency point to obtain the ideal running performance, working life and characteristic stability.
Generally, the use environment of DC gear motors is the same as that of micro DC motors. If there are special needs, such as ambient temperature, overload conditions, current limit, etc., it must be explained in advance.
The working life of the gearbox generally exceeds the working life of the DC motor, which can usually reach 1000 to 3000 hours. The total reduction ratio of the gearbox is generally in the range of 1:10 to 1: 500. After special design, it can reach 1: 1000 or more, but the gear box with a large reduction ratio is not allowed to "reverse", that is, the output shaft of the gear box cannot be used as the driving shaft to forcibly reverse.
Due to the limitation of gear strength, when the total transmission is large, the gear motor may not be able to withstand the locked torque, and the load torque at this time cannot exceed the maximum allowable short-term load torque. The gearbox consists of multi-stage gear pairs. Each stage consists of a pair of intermeshing gear pairs consisting of lamellar gears and pinions. The first pinion gear is mounted on the output shaft of the motor. The bearings used in the output shaft of the gearbox are usually oil-bearing bearings made of copper or iron materials.

 Precautions for installation and maintenance
1. Before use, please confirm whether the appearance of the geared motor is damaged or oil leakage.
2. Please confirm the operating voltage of the geared motor first. A voltage stabilizer can be installed when the voltage is unstable.
3. Please confirm whether the specifications of the geared motor you purchased match the design specifications.
4. Please confirm the fixed base to avoid loosening when running the drive.
5. If accessories such as sprockets, pulleys and couplings are used, they must be installed in accordance with the relevant regulations.
6. Lubricating grease has been put in the gear motor body, and no need to replace lubricating oil for 12000 hours.
7. When the geared motor is running, the rated current must not exceed the current indicated on the motor nameplate.
8. Please pay attention to the surrounding temperature, humidity, pH and other issues.
9. If not installed, maintained or operated in the correct way, it may cause serious damage to the geared motor.
10. When repairing or disassembling, make sure that the external power supply is completely separated from the gear motor.
11. The safety protection device must be installed to ensure absolute operation safety.
12. The motor needs to be grounded, please refer to the relevant power distribution regulations.
13. Please make sure that all the installation parts and transmission accessories are fixed correctly before starting the gear motor.
14. If the geared motor cooperates with the inverter to drive at low speed, an independent auxiliary cooling fan needs to be installed.
15. After the single-phase geared motor is powered off, some charges still remain in the capacitor. Please discharge or ground the terminal first.

Geared motor refers to the integrated body of geared motor and motor (motor). Such an integrated body may also be generally referred to as a gear motor or gear motor. Usually, it is supplied by a professional reducer manufacturer after integration and assembly.
The geared motor refers to the integrated body of the geared motor and the motor (motor). Such an integrated body may also be generally referred to as a gear motor or gear motor.
It is usually supplied by a professional reducer manufacturer after integrated assembly. Geared motors are widely used in the steel industry and machinery industry. The advantage of using a geared motor is to simplify the design and save space. After the Second World War, the rapid development of military electronic equipment has promoted the development and production of miniature gear motors and DC gear motors in the United States, the Soviet Union and other countries. With the continuous development of the gear motor industry, more and more industries and enterprises have used gear motors, and a number of enterprises have entered the gear motor industry. At present, Germany, France, Britain, the United States, China, South Korea and other countries maintain a leading level in the world of miniature gear motors and DC gear motors. China's miniature geared motor and DC geared motor industry was founded in the 1950s.

Gearbox use
1. Acceleration and deceleration, which is often referred to as a transmission gearbox.
2. Change the transmission direction, for example, we can use two sector gears to transmit the force vertically to another rotating shaft.
3. Change the rotating torque. Under the same power condition, the faster the gear rotates, the smaller the torque on the shaft, and vice versa.
4. Clutch function: We can separate the engine from the load by separating the two originally meshed gears, such as brake clutch, etc.
5. Distribute power. For example, we can use one engine to drive multiple slave shafts through the gearbox main shaft, so as to realize the function of one engine driving multiple loads. The working principle of the gearbox:
The gearbox is used for speed change, and the reduction gearbox or geared motor mostly uses gears to change the speed. As long as the principle is plain, it is a large gear with a small gear or a small gear with a large gear
It can be seen from the above introduction: once the gear ratio of the gear motor is selected, it cannot be changed.

1) Reduce the speed and increase the output torque at the same time. The torque output ratio is based on the motor output multiplied by the reduction ratio, but it should be noted that the rated torque of the reducer cannot be exceeded.
2) The speed reduction also reduces the inertia of the load. The reduction in inertia is the square of the reduction ratio. You can see that the general motor has an inertia value.
