Actually, should choose what kind of motor according to the specific application, each have its characteristics. Please see the table below, natural understand. Stepping motor system stepper motor torque range of small and medium-sized moment (Generally under 20 nm)Small cuhk, full range of low speed range,Generally below 2000 RPM, big torque motor is less than 1000 RPM)High (Up to 5000 RPM), dc stepper motor can reach 1 ~ 20000 RPM control mode is mainly position control intelligent control mode, diversified smoothness position/speed/torque when low speed vibration (But with subdivision drive type can be obviously improved)Good, smooth operation precision is generally low, subdivision drive type is relatively high (Depending on the resolution of the feedback device)Torque frequency features high speed, torque falling fast torque characteristic is good, hard overload characteristics overload will be out of step 3 ~ 10 times overload (A short time)Most feedback method for open loop control, also can meet the encoder, step to prevent the loss of the closed loop way, encoder type - encoder feedbackPhotoelectric rotary encoder (The incremental type/absolute value type)Response speed, rotating transformer type generally fast generally good vibration resistance (Rotating transformer can be resistant to vibration)High temperature operation temperature general maintenance basic can better prices low and maintenance-free the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
