Product Description


    Hybrid stepping motor combines the advantages of reactive type and permanent magnet type. Its stator has multi-phase windings. The permanent magnet material is used on the rotor. There are many small teeth on the rotor and stator to improve the step moment accuracy. Its characteristics are large output torque, good dynamic performance and small step angle, but its structure is complex and its cost is relatively high.

    According to the stator windings, there are two-phase, three-phase and five-phase series. The most popular one is the two-phase hybrid stepping motor, which accounts for more than 97% of the market share. The reason is that it has a high performance-price ratio and good effect with subdivision driver. The basic step angle of the motor is 1.8 degree per step. With the first half step driver, the step angle is reduced to 0.9 degree. With the subdivision driver, the step angle can be subdivided up to 256 times (0.007 degree/micro step). Because of friction and manufacturing accuracy, the actual control accuracy is slightly lower. The same stepper motor can be equipped with different subdivision drivers to change the accuracy and effect.
