DC motor
DC motor is the earliest motor. At the end of the 19th century, it can be roughly divided into two categories: commutator and non commutator. DC motor has better control characteristics. DC motor is inferior to AC motor in structure, price and maintenance. However, due to the problem of speed regulation control of AC motor has not been well solved, and DC motor has the advantages of good speed regulation performance, easy starting and load starting, DC motor is still widely used, especially after the emergence of thyristor DC power supply.
Application status: in life, there are countless applications of electric products. Fan, razor, etc. DC motors are used in automatic doors, automatic locks and automatic curtains in hotels. DC motors are widely used in aircraft, tanks, radar and other weapons and equipment. DC motor is also widely used in locomotive traction, such as railway locomotive DC traction motor, subway locomotive DC traction motor, locomotive DC auxiliary motor, mining locomotive DC traction motor, marine DC motor, etc. The figure above shows Z4 Series DC motor.
alternating current dynamo
Asynchronous motor is an AC motor that realizes energy conversion based on the interaction between air gap rotating magnetic field and rotor winding induced current to produce electromagnetic torque. Asynchronous motors are generally series products with a wide variety of specifications. They are most widely used in all motors and have the largest demand; At present, about 90% of machinery in electric drive uses AC asynchronous motor, so its power consumption accounts for more than half of the total power load.
Asynchronous motor has the advantages of simple structure, convenient manufacture, use and maintenance, reliable operation, low quality and low cost. Moreover, the asynchronous motor has high operation efficiency and good working characteristics. It runs at a constant speed from no-load to full load, which can meet the transmission requirements of most industrial and agricultural production machinery. Asynchronous motors are mainly used to drive most industrial and agricultural production machinery, such as machine tools, water pumps, blowers, compressors, hoisting equipment, mining machinery, light industrial machinery, agricultural and sideline products processing machinery, as well as household appliances and medical devices.
Application status: single phase asynchronous motor and three-phase asynchronous motor are more common in asynchronous motor. Three phase asynchronous motor is the main body of asynchronous motor. Three phase asynchronous motor can be used to drive all kinds of general machinery, such as compressor, water pump, crusher, cutting machine tool, transportation machinery and other mechanical equipment, which are widely used in mines.

Mechanics. It is used as prime mover in various industrial and mining enterprises such as metallurgy, petroleum, chemical industry and power station. For motors used to drive blowers, coal mills, rolling mills and hoists, relevant technical data shall be provided when ordering, and a technical agreement shall be signed as the basis for special design of motors to ensure reliable operation of motors.. Single phase asynchronous motors are generally used where three-phase power supply is inconvenient. Most of them are micro and small capacity motors, which are widely used in household appliances, such as electric fans, refrigerators, air conditioners, vacuum cleaners and so on.
synchronous motor
The so-called synchronous motor is a motor that runs synchronously with the rotating magnetic field of rotor and stator under the drive of AC. The stator of synchronous motor is exactly the same as that of asynchronous motor; However, there are two kinds of rotors: salient pole type and hidden pole type. It is suitable for low-speed synchronous motor with simple structure and low mechanical strength; The manufacturing process of hidden pole synchronous motor is complex, but its mechanical strength is high, so it is suitable for high-speed operation. The working characteristics of synchronous motor are the same as all motors. Synchronous motor also has "retrograde", that is, it can operate in the mode of generator or motor.
Application status: synchronous motors are mainly used in large machinery, such as blowers, water pumps, ball mills, compressors, rolling mills, small and micro instruments and equipment, or as control components; The three-phase synchronous motor is its main body. In addition, it can also be used as a condenser to transmit inductive or capacitive reactive power to the power grid.

Signal motor
Position signal motor
At present, the most representative position signal motors are resolver, inductosyn and synchro.
Introduction: resolver / transformer is an electromagnetic sensor, also known as synchronous resolver. It is a small AC motor used to measure the angle. It is used to measure the angular displacement and angular velocity of the rotating shaft of the rotating object. It is composed of stator and rotor. As the primary side of the transformer, the stator winding receives the excitation voltage, and the excitation frequency is usually 400, 3000 and 5000Hz. As the secondary side of the transformer, the rotor winding obtains the induced voltage through electromagnetic coupling.
Application status: resolver is a kind of precision angle, position and speed detection device, which is suitable for all resolver resolver resolver occasions where rotary encoder is used, especially in occasions where rotary encoder cannot work normally, such as high temperature, severe cold, humidity, high speed and high vibration. Due to the above characteristics, the resolver can completely replace the photoelectric encoder and is widely used in angle and position detection systems in servo control systems, robot systems, mechanical tools, automobiles, electric power, metallurgy, textiles, printing, aerospace, ships, weapons, electronics, metallurgy, mines, oil fields, water conservancy, chemical industry, light industry, construction and other fields. It can also be used for coordinate transformation, triangulation and angle data transmission. It can also be used in angle digital conversion device as a two-phase phase shifter.
Inductosyn
Displacement sensor that converts angular or linear displacement signal into AC voltage, also known as planar resolver. It has two types: disc type and linear type. In the high-precision digital display system or NC closed-loop system, the disk inductosyn is used to detect the angular displacement signal, and the linear inductosyn is used to detect the linear displacement. Inductosyn is widely used in high-precision servo turntable, radar antenna, positioning and tracking of artillery and radio telescope, precision CNC machine tools and high-precision position detection system.
Application status: inductosyn has been widely used in large displacement static and dynamic measurement, such as CMM, program-controlled CNC machine tools, high-precision heavy machine tools and measuring devices of machining centers.
Inductosyn uses the principle of electromagnetic coupling to realize displacement detection, which has obvious advantages: high reliability, strong anti-interference ability, low requirements for working environment, can work normally without constant temperature control and poor environment, and is suitable for the harsh environment of industrial site; Grating sensor realizes displacement detection based on photoelectric mechanism. It has high resolution, accurate measurement and convenient installation and use. The closed grating sensor is more widely used in length measurement than inductosyn because of its strong adaptability to the working environment, the improvement of the performance price ratio of grating sensor and the reduction of technical complexity.
synchro
Synchro is an induction micro motor that changes the angle into AC voltage or from AC voltage to angle by using the characteristics of self-tuning step. It is used as a displacement sensor to measure the angle in the servo system. The synchro can also be used to realize the long-distance transmission, transformation, reception and indication of angle signals. Two or more motors can automatically maintain the same angle change or synchronous rotation of two or more rotating shafts that are not connected to each other mechanically through the connection of circuits. This performance of the motor is called self-tuning characteristic. In the servo system, the synchro used by the party generating the signal is called the transmitter, and the synchro used by the party receiving the signal is called the receiver. Synchro is widely used in position and azimuth synchronous indication systems such as metallurgy and navigation, and servo systems such as artillery and radar.

Speed signal motor
The most representative speed signal motor is the tachogenerator, which is essentially an electromechanical magnetic element that converts the speed into an electrical signal, and its output voltage is directly proportional to the speed. In terms of working principle, it belongs to the category of "generator". The tachogenerator is mainly used as damping element, differential element, integral element and tachometer element in the control system. So I won't elaborate too much here.
Types and differences of motors?
1. According to the type of working power supply: it can be divided into DC motor and AC motor
2. According to the structure and working principle, it can be divided into DC motor, asynchronous motor and synchronous motor.
3. According to the starting and operation modes: capacitor starting single-phase asynchronous motor, capacitor running single-phase asynchronous motor, capacitor starting running single-phase asynchronous motor and split phase single-phase asynchronous motor.
4. Divided by purpose: drive motor and control motor.
5. According to the structure of rotor: cage induction motor (called squirrel cage induction motor in the old standard) and wound rotor induction motor (called wound induction motor in the old standard).
6. Divided by operating speed: high-speed motor, low-speed motor, constant speed motor and speed regulating motor. Low speed motors are divided into gear reduction motors, electromagnetic reduction motors, torque motors and claw pole synchronous motors.
Servo motor is a kind of servo device used in servo motor control system. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. In an automatic control system, it is used as an actuator to convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into DC and AC servo motors. Its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of torque.
