A hybrid stepper motor combines the best features of a standard variable reluctance step motor and a permanent magnet step motor. This hybrid of the two types of stepper motors allows the hybrid step motor to generate a great amount of power despite its small size.
The hybrid stepper motor is multi-toothed like the variable resistance motor but contains permanent magnets like a permanent magnet motor. In effect, the hybrid stepper is sort of like a permanent magnet stepper motor "plus". A variable stepper motor relies on those teeth to move the motor accurately, while the permanent magnet stepper relies on the magnets. The hybrid has both features to work with, resulting in an overall more accurate stepper. Hybrid stepper motors provide high resolution angular positioning and are good for applications requiring high repeatability and high torque in a small package size. Stepper motors provide excellent performance at low speeds. Positioning accuracy of +/-5% of the step angle means a hybrid step motor is ideal for open loop control, but can be paired with an encoder to run closed loop for added accuracy.
