Tips: Advantages and disadvantages of stepper motor
A. Advantages
- The rotational angle of motor is in direct proportion to number of pulses.
- The torque is the largest when the motor stops rotating (when winding is excited).
- As the precision of each step is 3% to 5% and the error at one step will not be accumulated to the next one, so there is good position accuracy and repeatability of motion.
- Excellent start and stop and inversion response.
- Without electric brush, the reliability is high. Therefore, the service life of motor only depends on that of bearing.
- The response of motor is determined by the digital input pulse, so open-loop control can be adopted. As a result, the structure of the motor can be simple and the cost can be controlled.
- Synchronous rotation at extremely low velocity by only directly connecting the load to the spindle of motor.
- For the velocity is in direct proportion to the pulse frequency, there is wide range of rotational velocity.
B. Disadvantages
- If not controlled properly, the resonance can be easily caused.
- Hard to rotate at high rotational velocity.
- Hard to obtain large torque.
- No advantage over volume and weight and low utilization ratio of energy resources.
