A stepper motor A bipolar hybrid stepper motor. Brushed DC motors rotate continuously when DC voltage is applied to their terminals. The stepper motor is known for its property of converting a train of input pulses (typically square waves) into a precisely defined increment in the shaft’s rotational position.
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .

Code breakers at Bletchley Park employed uniselectors driven by a continuously rotating motor rather than a series of pulses in the Colossus to cryptanalyse the German Lorenz ciphers. [1] In a uniselector, the stepping switch steps only along or around one axis, although several sets of contacts are often operated simultaneously.
Lavet-type stepping motor of a quartz clock. A black rotor sprocket provides the mechanical output. The Lavet-type stepping motor has widespread use as a drive in electro-mechanical clocks [1] and is a special kind of single-phase stepping motor. Both analog and stepped-movement quartz clocks use the Lavet-type stepping motor (see Quartz clock).
Chopper circuits are used in multiple applications, including: Switched mode power supplies, including DC to DC converters.; Speed controllers for DC motors; Driving brushless DC torque motors or stepper motors in actuators
Bimorph cantilevers used in stepper or walk drive motor. Not to be confused with the similarly named electromagnetic stepper motor, these motors are similar to the inchworm motor, however, the piezoelectric elements can be bimorph actuators which bend to feed the slider rather than using a separate expanding and contracting element.
