Application occasions and advantages induction of stepper motor.
Advantage: High Control Accuracy.
Features: compared with ordinary motor, it can achieve open-loop control, that is, through the driver signal input pulse number and frequency of stepping motor angle and speed control, without feedback signal. But stepper motor is not suitable for use in the long run in the same direction, easy to burn products, even when the use is usually short-distance frequent action better. In contrast to servomotors, the internal feedback control is achieved by installing a rotary encoder.
The torque that the servomotor can achieve is higher than that of the stepper motor, but the price is also relatively high, so if the Torque can be met, stepper motor is recommended.
Stepper motor with the use of drivers, many drivers are supporting subdivision function, that is to achieve a small stepper angle, more accurate control.
