STS hybrid stepping motor

 Stepper motors are divided into three types: PM, VR and HB. Reactive stepper motor is generally two-phase, torque and volume is small, the stepping Angle is generally 7.5 degrees or 1.5 degrees;Permanent magnet stepper motor is generally three-phase, can achieve large torque output, stepping Angle is generally 1.5 degrees, but the noise and vibration are very large;Hybrid stepper motor is divided into two phase, three phase and five phase, two phase stepping Angle is generally 1.8 degrees, three phase stepping Angle is generally 1.2 degrees and five phase stepping Angle is generally 0.72 degrees.Hybrid stepper motor combines the advantages of both reactive and permanent magnet stepper motors: the polar logarithm is equal to the number of rotor teeth, which can be changed in a large range according to needs;The winding inductance changes little with the rotor position, which is easy to realize the best operation control.Axial magnetizing magnetic circuit, using a new type of permanent magnet material with high magnetic energy product, is conducive to the improvement of motor performance;Rotor magnetic steel provides excitation;There are no noticeable oscillations in the entire operating area.
