With the constant improvement of the industrial automation level, step motor stepper technology in all fields in the application of improved, stepper motor and stepper motor more and more be used to replace the traditional control mode. For the step and step motor selection but there are a lot of people don't understand, this article is in view of the stepper motor selection do some introduction in practical application. Since the launch of stepper motor operation mode refers to the drive motor rotation and stops without acceleration and deceleration phase, and directly to the corresponding pulse frequency of start and stop the operation. Since the launch of stepper motor operation mode, usually used in the rotational speed is low,Generally no more than 3 -4 r/s)。 At the same time, because the start/stop when there is a sudden change of speed, so this way need to larger/deceleration torque. Stepper motor plus/deceleration operation mode refers to the first start at a lower speed, after an accelerating process to achieve the normal pulse frequency, running again after a period of time after a deceleration motor to stop operation mode. The positioning time includes acceleration time, deceleration time, and the corresponding pulse frequency run time. 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.
