Stepper motor heating although generally will not affect the life of the motor, for the majority of customers don't need to ignore. But serious will bring some negative impacts. Internal parts such as motor thermal expansion coefficient of different lead to the change of structural stress and internal air gap of tiny change, affects the dynamic response of the motor, high speed will be easy to out of step. And as some situation does not allow excessive heating of the motor, such as medical equipment and high-precision test equipment, etc. So the control of the heating of the motor should be necessary. To reduce fever, is to reduce the copper loss and iron loss. Reduce copper loss, there are two directions, resistance and current, choose as far as possible when this request in the selection of small resistance and the rated current of the motor, the two-phase motor, motor without parallel in tandem. But this often conflict with the moment and the requirement of high speed. For motor has been selected, should make full use of the stepper motor drive automatic flow control function and offline function, the former automatically reduce current when motor is static, the latter will be the current be cut altogether. In addition, the subdivision driver due to the current waveform is close to sine, less harmonic, electric heating will be less. Reduce iron loss method, related voltage level, although will bring high speed characteristics of high pressure driven motor, but also brings the increase of the heat. So should choose the appropriate drive voltage grade, recommend suite, give attention to two or morethings stationarity and fever, noise, etc. 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.
