A hybrid stepper motor is a combination of the variable reluctance and permanent magnet type motors. The rotor of a hybrid stepper motor is axially magnetized like a permanent magnet stepper motor, and the stator is electromagnetically energized like a variable reluctance stepper motor.
Products are widely used in lithium equipment, CNC machine tools,
Laser equipment, wire equipment, labeling equipment, dispensing equipment and Medical equipment, etc.

Hybrid stepper motors combine the operating principles of variable reluctance with permanent-magnet stepper motors. The rotor shaft holds one or more pairs of stacked laminations containing many teeth along its outside diameter. A permanent magnet between each laminated stack pair creates a north and south pole oriented along the motor shaft axis.
Conventional electric motors rotate continuously, but stepper motors rotate or step in fixed angular increments. One revolution involves the motor taking a specific number of steps determined by the number of teeth, motor construction, and type of drive scheme used for control. This measurement, called the step angle or step resolution, can be stated as an angular measurement or a specific number of steps. The most commonly specified step resolution is 1.8°/step or 200 steps/rev.
Compared with servomotors, hybrid steppers have the advantage of rugged, simple construction; reliability with little maintenance; high torque at low speeds; and no need for position or velocity feedback devices. Comparative disadvantages include diminished torque at high speeds; resonance and noise; and high consumption of current. Where precise positioning is a must, hybrid steppers best suit applications characterized by stable loads and speeds under 1,000 rpm.
