What are the advantages and disadvantages of stepping motors?
The advantages of the stepper motor are as follows:1. when the motor is stopped, it has the maximum torque (when the winding is exciting);2. the angle of rotation of the motor is proportional to the number of pulses;The response of the 3. motor is determined only by the digital input pulse, so open-loop control can be employed, which allows the structure of the motor to be relatively simple and control costs;4. due to step precision in three percent to five percent, and the error will not be one step to the next step of the accumulation of good repeatability and position accuracy and motion;5. excellent start stop and reverse response;6. because there is no brush, the reliability is high, so the life of the motor only depends on the life of the bearing;
4., there is no advantage in volume and weight, and the utilization rate of energy is low.5. over load will damage synchronization, vibration and noise will occur when working at high speed.
The disadvantages of stepper motors are as follows:1. if the control is improper, it is easy to produce resonance;2. difficult to run to higher rpm.3. it is difficult to obtain larger torque
