Types and characteristics of wholesale nema 14 stepper motor
There are three main types of stepper motors in construction: reactive, permanent magnet and hybrid.
Reaction Formula:
There are windings on the stator, the rotor is made of soft magnetic material. The utility model has the advantages of simple structure, low cost, small step angle, up to 1.2, but poor dynamic performance, low efficiency, large heating, and difficult reliability guarantee.
Permanent Magnet type:
the Rotor of permanent magnet type stepper motor is made of permanent magnet material. The Pole number of the rotor is the same as that of the stator. It is characterized by good dynamic performance, output Torque, but this motor accuracy, step moment angle is large (usually 7.5 or 15) .
Hybrid:
the Hybrid stepper motor combines the advantages of reactive and permanent magnet, with multi-phase windings on the stator, permanent magnet material on the rotor, and multiple small teeth on the rotor and stator to improve the precision of the stepping moment. It is characterized by large output Torque, good dynamic performance, small moment angle, but complex structure and relatively high cost.
