  2. Stepper motor - Wikipedia

    en.wikipedia.org/wiki/Stepper_motor

    A stepper motor, also known as step motor or stepping motor, [1] is a brushless DC electric motor that rotates in a series of small and discrete angular steps. [2] Stepper motors can be set to any given step position without needing a position sensor for feedback. The step position can be rapidly increased or decreased to create continuous ...

  3. Stepper - Wikipedia

    en.wikipedia.org/wiki/Stepper

    A stepper or wafer stepper is a device used in the manufacture of integrated circuits (ICs). It is an essential part of the process of photolithography , which creates millions of microscopic circuit elements on the surface of silicon wafers out of which chips are made.

  4. Rotary actuator - Wikipedia

    en.wikipedia.org/wiki/Rotary_actuator

    A servomotor is a packaged of several components: a motor (usually electric, although fluid power motors may also be used), a gear train to reduce the many rotations of the motor to a higher torque rotation, a position encoder that identifies the position of the output shaft and an inbuilt control system. The input control signal to the servo ...

    6: square thread DVD drive with leadscrew and stepper motor Floppy disc drive with leadscrew and stepper motor. A leadscrew (or lead screw), also known as a power screw [1] or translation screw, [2] is a screw used as a linkage in a machine, to translate turning motion into linear motion.

  6. Reluctance motor - Wikipedia

    en.wikipedia.org/wiki/Reluctance_motor

    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 .

  9. Motor controller - Wikipedia

    en.wikipedia.org/wiki/Motor_controller

    A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...
