Hybrid Stepper Motors
Hybrid refers to a combination or mixture. Hybrid stepper motors or HB stepper motors combine the features of variable reluctance stepper motors and permanent magnet stepper motor. The shaft of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. For precise positioning, Hybrid stepper motors are the best choice. All kinds of control signals, such as digital, analog, communication, etc, are widely used in a variety of applications for position and speed. A variety of HB motor types are available, including the primary type, encoder type, IP65 type, integrated type with drive and controller, brake type, and geared type.
Permanent Magnet Stepper Motors
Permanent magnet stepper motors use a permanent magnet (PM) in the rotor and operate on the attraction or repulsion between the rotor PM and the stator electromagnets. The step angle for permanent magnet stepping motors is usually 3.75°, 7.5°, 15°, or 18°, depending on the model. They are generally two-phase, have low torque and volume, and have a small step angle.
