And stepper motor drives the choice of a lot of people don't really know, don't know how to, the following is to make a brief introduction. Stepper motor selection method: 1, you can choose how much torque, static torque can be said to be the main parameters choice of stepper motor, itself a larger load, requires a large torque motor, the torque index of age, of course, the appearance of motor is relatively large. 2, judge motor speed, speed requirements higher, should choose phase current is larger, the relatively small inductance of the motor, this convenient to increase the power of the input, and select the drive to adopt higher power supply voltage. 3, choose motor installation specification is very important also, mainly related to torque requirements. 4, determine the positioning accuracy to judge whether need to segment, and how many segments. 5, according to the current of motor, segment and to select the drive power supply voltage. 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.
