Wholesale Stepmotor

- Nov 06, 2020-

When we wholesale stepping motor, we should pay attention to three types of stepping motor, reaction formula: stator winding, rotor composed of soft magnetic material.Simple structure, low cost, small step Angle, up to 1.2°, but poor dynamic performance, low efficiency, high heating, reliability difficult to guarantee.

Permanent magnet type: 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 that of the stator.It is characterized by good dynamic performance and large output torque, but the motor has poor accuracy and large step moment Angle (generally 7.5° or 15°).

Hybrid type: Hybrid stepping motor combines the advantages of reactive and permanent magnet type. The stator has polyphase windings, the rotor USES permanent magnet material, and the rotor and stator have several small teeth to improve the stepping moment accuracy.Its characteristics are large output torque, good dynamic performance, small step Angle, but complex structure, relatively high cost.

According to the stator winding, there are two - phase, three - phase and five equal series.
