The advantages and disadvantages of several stepper motors are introduced

Perhaps you also know that from the form of the structure can be divided into reactive motor, permanent magnet motor, hybrid motor and many other different types, from the control mode, it can be divided into open loop control system, closed loop control system and semi-closed loop control system these different types. In terms of these different kinds of motors, they all have certain advantages and disadvantages, such as:

Reactive motor: Because the stator has a winding and the rotor is composed of soft magnetic materials, this stepping motor has the advantages of simple structure, low cost and small step Angle, but it also has the disadvantages of poor dynamic performance, low efficiency and large heat, which is difficult to guarantee in terms of reliability.

Permanent magnet motor: The rotor of the permanent magnet stepper motor is made of permanent magnet material, the number of poles of the rotor is the same as the number of poles of the stator, so it has the advantages of good dynamic performance and large output torque, but this motor also has the disadvantages of poor accuracy and large step moment Angle.

Hybrid motor: This kind of stepper motor in terms of advantages, is the synthesis of reactive and permanent magnet motors, a collection of many advantages of the two, in the output torque is large, but also has a good dynamic performance, while the step Angle is relatively small, but the structure of the motor is relatively complex, in the production and manufacturing time has a certain difficulty, the cost of production is relatively high.
