What are hybrid stepper motors?
Hybrid stepper motors combine aspects of both permanent magnet (PM) and variable reluctance (VR) stepper motors. Like PM motors, they contain a permanent magnet in the rotor teeth. Two sets of teeth called cups ring the rotor. One ring is all south poles, and the other ring is all north poles.
Like VR motors, hybrid stepper motors have stator poles. Note that stator poles in hybrid motors are sometimes called teeth.
Our Hybrid stepper motot Model No.:PST57H245-4P10, the calling name system can be checked as below:
