Buy motor printer, control motor is divided into stepper motor and servo motor.
According to the structure of the rotor classification according to the structure of the motor according to the rotor, can be divided into squirrel cage induction motor (old standard called squirrel cage asynchronous motor) and winding rotor induction motor (old standard called winding asynchronous motor).
Classification by running speed According to different motor running speed, can be divided into high speed motor, low speed motor, constant speed motor, speed regulating motor. Low speed motors are divided into gear reduction motors, electromagnetic reduction motors, torque motors and claw pole synchronous motors. Speed regulating motor can be divided into graded constant speed motor, stepless constant speed motor, graded variable speed motor and stepless variable speed motor, also can be divided into electromagnetic speed regulating motor, DC speed regulating motor, PWM variable frequency speed regulating motor and switched reluctance speed regulating motor. The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field. The rotor speed of a synchronous motor is always synchronous regardless of the load.
