Operating procedures of vibrator
1. Before use, it is necessary to check whether the rotation direction of the motor is consistent with the marking direction, and whether the connection of all parts is fastened. It can be used only after it is confirmed to be good.
2. Operators shall wear insulating gloves and shoes to avoid electric shock.
3. During operation, the bending radius of the hose shall not be less than 50cm, the vibrating rod shall not be inserted too deep, and the tail of the rod shall be exposed for 1 / 3 ~ 1 / 4; The flexible shaft shall not be inserted into the concrete, otherwise it will be squeezed by the vibrated concrete and it will not be easy to pull out.
5. When pulling the plate vibrator with a rope, the stay wire must ensure insulation and dryness. The two people should cooperate closely. When moving and turning, they should step on both ends of the plate and not on the motor.
6. After the vibrating rod operates normally, the rod head shall be sunk into the concrete along the force, and it is not allowed to insert it hard. When pulling the pipe, it is not allowed to use too much force to prevent damage to mechanical parts and accidents.
7. When the plug-in vibrator vibrates on the reinforcement mesh, pay attention not to damage the reinforcement by clamping the vibrating rod or touching the hard object. In addition, pay attention to the insulation of the wire at any time; In case of leakage or motor zero line falling off, the power supply shall be cut off in time for repair.
8. During operation, when the plate vibrator moves, the conductor of the motor must be kept with sufficient length and looseness, and it shall not be tensioned, so as to prevent the wire head from being broken.
9. The power cord should be overhead as far as possible and checked frequently. It is not allowed to drag it in the cement mortar, so as not to damage the insulating cord and make the surrounding area conductive.
10. The outer surface of the vibrator shall be kept clean, and the cement slurry shall not be bonded to the motor shell, so as not to hinder the heat dissipation of the motor.
11. When working in rainy days, try to cover the motor of the vibrator to avoid rain immersion. Wet hands are not allowed to touch the electrical switch.
12. When operating the vibrator, the motor temperature shall not exceed 75 ℃, otherwise it shall be shut down for cooling; If any fault is found during operation, stop the machine for troubleshooting.

The importance of motor is self-evident. Modern life is inseparable from electricity, and naturally it is inseparable from motor. Motor is an important part of transmission and control system. With the development of modern science and technology, the focus of motor in practical application has begun to shift from simple transmission to complex control; Especially for the accurate control of motor speed, position and torque. Next, we will gradually introduce the three most representative, commonly used and basic motors.
1. Torque motor
The so-called torque motor is a flat multipole permanent magnet DC motor. The armature has more slots, commutators and series conductors to reduce torque ripple and speed ripple. There are two kinds of torque motors: DC torque motor and AC torque motor.
Among them, the self inductance reactance of DC torque motor is very small, so the response is very good; The output torque is directly proportional to the input current and has nothing to do with the speed and position of the rotor; It can directly connect with the load at low speed without gear deceleration when it is close to the locked rotor state, so it can produce a high torque to inertia ratio on the load shaft and eliminate the systematic error caused by the use of reduction gear.
AC torque motor can be divided into synchronous and asynchronous. At present, squirrel cage asynchronous torque motor is commonly used, which has the characteristics of low speed and strong torque. Generally, AC torque motor is often used in textile industry. Its working principle and structure are the same as that of single-phase asynchronous motor. However, due to the large resistance of squirrel cage rotor, its mechanical characteristics are relatively soft.
2 switched reluctance motor
Switched reluctance motor is a new type of speed regulation motor, which has extremely simple and solid structure, low cost and excellent speed regulation performance. It is a strong competitor of traditional control motor and has strong market potential. However, there are also some problems such as torque ripple, running noise and large vibration, which need some time to optimize and improve to adapt to the actual market application. 5. Brushless DC motor
Brushless DC motor (BLDCM) is developed on the basis of Brushless DC motor, but its driving current is AC to the letter; Brushless DC motor can be divided into brushless speed motor and brushless torque motor. Generally, there are two kinds of driving current of brushless motor, one is trapezoidal wave (generally "square wave"), and the other is sine wave. Sometimes, the former one is called brushless DC motor, and the latter one is called AC servo motor. To be exact, it is also a kind of AC servo motor.

Brushless DC motor (BLDCM) is developed on the basis of Brushless DC motor, but its driving current is AC to the letter; Brushless DC motor can be divided into brushless speed motor and brushless torque motor. Generally, there are two kinds of driving current of brushless motor, one is trapezoidal wave (generally "square wave"), and the other is sine wave. Sometimes, the former one is called brushless DC motor, and the latter one is called AC servo motor. To be exact, it is also a kind of AC servo motor.
In order to reduce the moment of inertia, brushless DC motor usually adopts "slender" structure. Brushless DC motor is much smaller in weight and volume than brushless DC motor, and the corresponding moment of inertia can be reduced by about 40% - 50%. Due to the processing problem of permanent magnet materials, the general capacity of Brushless DC motor is less than 100kW.
This kind of motor has good linearity of mechanical characteristics and regulation characteristics, wide speed regulation range, long service life, convenient maintenance, low noise and no series of problems caused by brush. Therefore, this kind of motor has great application potential in the control system. 1. Servo motor
Servo motor is widely used in various control systems. It can convert the input voltage signal into the mechanical output on the motor shaft and drag the controlled components to achieve the purpose of control. Generally, the speed of servo motor is required to be controlled by the applied voltage signal; The rotating speed can continuously change with the change of the applied voltage signal; The torque can be controlled by the current output by the controller; The response of the motor should be fast, the volume should be small and the control power should be small. Servo motor is mainly used in various motion control systems, especially servo system.
Servo motor can be divided into DC and ac. the earliest servo motor was a general DC motor. When the control accuracy was not high, the general DC motor was used as the servo motor. At present, with the rapid development of permanent magnet synchronous motor technology, most servo motors refer to AC permanent magnet synchronous servo motor or DC brushless motor.
3. Stepping motor
The so-called stepping motor is an actuator that converts electric pulse into angular displacement; More generally speaking: when the stepping driver receives a pulse signal, it drives the stepping motor to rotate a fixed angle in the set direction. We can control the angular displacement of the motor by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation. At present, the commonly used stepping motors include reactive stepping motor (VR), permanent magnet stepping motor (PM), hybrid stepping motor (HB) and single-phase stepping motor.

The difference between stepper motor and ordinary motor mainly lies in the form of pulse drive. It is this feature that stepper motor can be combined with modern digital control technology. However, the stepper motor is inferior to the traditional closed-loop DC servo motor in control accuracy, speed variation range and low-speed performance; Therefore, it is mainly used in occasions where the accuracy requirement is not particularly high. Because stepping motor has the characteristics of simple structure, high reliability and low cost, stepping motor is widely used in various fields of production practice; Especially in the field of NC machine tool manufacturing, because the stepping motor does not need a / D conversion and can directly convert the digital pulse signal into angular displacement, it has always been considered as the most ideal actuator of NC machine tool.
In addition to its application in CNC machine tools, stepper motors can also be used in other machines, such as motors in automatic feeders, motors in general floppy disk drives, printers and plotters.
In addition, stepper motor also has many defects; Because the stepper motor has no-load starting frequency, the stepper motor can operate normally at low speed, but it cannot be started if it is higher than a certain speed, accompanied by sharp whistling; The precision of subdivision drivers from different manufacturers may vary greatly. The greater the subdivision, the more difficult it is to control the precision; Moreover, the stepping motor has large vibration and noise when rotating at low speed.
