What is the difference between stepper motor and servo motor?

Stepper motor and servo motor applications are more extensive, many friends often like to compare the two, although they are motors, many times can achieve the same effect, but the two in the performance and application, there are still some differences, so what is the difference between stepper motor and servo motor? NOYU briefly introduce it to you!
 

1. The difference in operation principle is that the stepper motor is mainly to change the electrical pulse signal into a control element of linear displacement or angular displacement after processing; The servo motor needs pulse positioning to achieve closed loop, which can control the motor operation and accurate positioning.

2. Different running performance, stepper motor is mostly open loop, if the starting frequency is high, or the load is large, it is easy to produce out-of-step phenomenon; The servo motor uses a closed loop, which is easier to control and does not produce out-of-step.

3. Speed and overload capacity difference, stepper motor low-speed operation is easy to low-frequency vibration, servo motor will not have, mainly closed-loop reasons, stepper motor rated speed is less than the servo motor, overload capacity is relatively small.

4. The difference of low frequency characteristics, the stepper motor has resonance point, need to adjust the control operation method, inhibit resonance, improve the stability of the medium frequency, so that the high-speed running torque output is larger and more stable; The servo motor will not have resonance when running at low speed, and the operation is relatively stable.

5, the cost price, the same functional requirements, the price of the servo motor is certainly more expensive than the stepper motor, in the cost performance above, the stepper motor of course still has advantages, if there are high requirements for speed response and accuracy, you can use the servo motor.

How to wind stepper motor stator?

Stepper motor stator is mostly internal winding, there are a variety of models, generally using a special internal winding machine to wind work, can be double station, four station or six station equipment, according to the stator diameter and wire diameter size to choose the suitable winding machine equipment.

What is the difference between stepper motor and servo motor? How to wind stepper motor stator? After reading the above content I believe you also understand, I hope these little knowledge can help you!
