Can making machine Servo motors and applications
Now, more and more servo motors are used in the equipment of can making.The popularization of servo motor greatly reduces the transmission system of the equipment and makes the control more convenient, fast and accurate.So what is a servo motor?Here is a popular science.
Servo motors, also known as execution motors, are used as execution elements in the control system to convert the input voltage control signal into the output angular displacement and angular velocity on the axis to drive the control object.Its biggest features:
The rotor rotates immediately with control voltage and stops immediately without control voltage.The direction and magnitude of the control voltage determine the direction and speed of the shaft.Can be divided into dc servo motor and ac servo motor.The motor consists of a stator, a rotor, an encoder and a housing.The speed can be controlled by changing the control voltage.The main function of the driver is to output the control voltage proportional to the given signal, receive the speed and position signal of the encoder, and I/O signal interface.
Ac servo motors should be used in general automatic control applications as far as possible.Dc servo motor or other special control motor, such as linear motor, should be used in the occasions of high speed regulation and control accuracy.According to the working mode and the conditions of the common ancestor environment, different types of structure are selected, such as frequently starting and stopping occasions using the hollow cup rotor structure of the servo motor, such as the speed requirements for more balanced occasions using large inertia servo motor.Power selection is not economical, too small motor overload and damage.For servo motors in continuous operation, the selected power shall be equal to or slightly greater than the power of the production machinery.For short-time working servomotors, the selected power may be equal to or slightly less than the power of the production machine, because a transient overload is allowed during operation.
The core of the stator is formed by the inner grooved silicon steel sheet, which generates a magnetic field by rotating. The rotor is subject to the action of the rotating magnetic field and thus rotates with the rotating magnetic field.An encoder is a device that compiles signals or data and converts them into signals that can be used for communication, transmission, and storage.It is installed in the rear end of the motor, and its turntable is coaxial with the motor.
