Hybrid Stepper Actuators

Hybrid Stepper Actuators combine qualities from the both permanent magnet and variable reluctance stepper actuator motors. The Hybrid stepper actuator motors have some of the desirable features of each. These stepper actuator motors have a high detent torque, excellent holding and dynamic torque, and they can operate in high step speeds. Step angles of 0.9 to 5.0 degrees are normally seen in hybrid stepper actuator motors. Bipolar windings are generally supplied to these stepper actuator motors, so a single power supply can be used to power the stepper actuator motors. The rotor will rotate in increments of 1.8 degrees, if the phases are energized one at a time in the order they are indicated at. These Actuator Motors can be driven in two phases at a time to yield more torque. Hybrid stepper actuator motors can also be driven by one, then two, then one phase to produce half-steps of 0.9 degree increments. Typically hybrid stepper actuators are more costly due to the combined characteristics.
