Now, more and more servo motors are used in canning equipment. The popularity of servo motors has greatly reduced the transmission system of the can making machine, and the control is more convenient, faster and more accurate. So what is a servo motor? Here is some science for everyone.

Servo motors are also called executive motors. They are used as actuators in the control system to convert the input voltage control signal into the angular displacement and angular velocity output on the shaft to drive the control object. Its greater features:

When there is a control voltage, the rotor rotates immediately, and when there is no control voltage, the rotor stops immediately. The direction and speed of the rotating shaft are determined by the direction and magnitude of the control voltage. It can be divided into DC servo motor and AC servo motor. All are composed of a motor and a driver. The motor is composed of a stator, a rotor, an encoder and a housing. By changing the size of the control voltage, the speed can be controlled. The main function of the driver is to output a control voltage proportional to this according to a given signal, receive the speed and position signals of the encoder, and I/O signal interface.

In general automatic control applications, AC servo motors should be used as much as possible. Select DC servo motors or other special control motors, such as linear motors, for occasions with high speed regulation and control accuracy; choose different structure types according to the working mode and the conditions of the father’s environment, such as the hollow cup rotor for frequent start and stop occasions The structure of the servo motor, such as the occasion where the speed is required to be more balanced, select the large inertia servo motor. The selection of power is too large and it is not economical, and the motor is easily overloaded and damaged if it is too small. For continuously running servo motors, the selected power should be equal to or slightly greater than the power of the production machinery. For short-time servo motors, a short-term overload is allowed during operation, so the selected power can be equal to or slightly less than the power of the production machinery.

The iron core of the stator is composed of silicon steel sheets with slots on the inner circumference. The magnetic field is generated by rotation, and the rotor is subjected to force under the action of the rotating magnetic field, thereby rotating with the rotating magnetic field. Encoder is a device that compiles signals or data and converts them into signal forms that can be used for communication, transmission and storage. Installed at the back end of the motor, the turntable is coaxial with the motor.
