STEPPING MOTOR(Torque-speed Characteristic、Noise-Speed Charactisic、Rising Temperautre-Speed Charactisic)

      The stepping motor is an electriomechal device which converts eletrical pulses into discrete mechanicle movements. It has many advantages such as periodicity accumulative angle error,low-cost, simplly controlled .etc. According to the pahse numbers, it can be classfied to 2-phase,3-phase,4-phase or 5-phase. According to the dimensions, it can be made from 42mm to 130mm. According to the holding torque, it can be from 0.1N﹒m to 8N﹒m. The maxium
input power can be over 1500W.

STEPPING MOTOR DRIVER 

     The stepping motor driver is special used to drive the stepping motor. According to the driving methods, it can be classifed to contant-voltage diver , constant-current driver, PWM driver etc. According to the division numbers it can be from 1 to 256. According to the phase current , it can be from 1A to 8A. The D-serice driver is special in lower noise ,sligher vibration, lower rising temperature.(The partent number is 200820163154.2)
