The principle and characteristics of servo motor controller
the stepping servo motor controller is using principle of electromagnet, the pulse signal is converted into linear displacement or angular displacement of the motor controller. Each to a electrical impulses, hut a certain rotary Angle of stepping motor controller, drive the mechanical move a short distance. Characteristics: the stepping servo motor controller 1) Turn to a pulse, a step from the Angle of. ( 2) Control pulse frequency, which can control the motor speed controller. ( 3) Change the pulse sequence, can change the direction of rotation. Since stepping servo motor controller of the job functions exactly conform to the requirements of the digital control system, so it is in the numerical control machine tool, clock and watch industry and have a wide range of applications in such aspects as recorder.
