  2. Armature Controlled DC Motor - Wikipedia

    en.wikipedia.org/wiki/Armature_Controlled_DC_Motor

    A motor requiring a DC power supply for operation is termed a DC motor. DC motors are widely used in control applications like robotics, tape drives, machines and many more. Separately excited DC motors are suitable for control applications because of separate field and armature circuit. [1] Two ways to control DC separately excited motors are ...

  3. Ward Leonard control - Wikipedia

    en.wikipedia.org/wiki/Ward_Leonard_control

    The key feature of the Ward Leonard control system is the ability to smoothly vary the speed of a DC motor, including reversing it, by controlling the field and hence the output voltage of a DC generator, as well as the field of the motor itself. As the speed of a DC motor is dictated by the supplied voltage, this gives simple speed control ...

  4. Armature (electrical) - Wikipedia

    en.wikipedia.org/wiki/Armature_(electrical)

    A DC armature of a miniature motor (or generator) An example of a triple-T armature A partially-constructed DC armature, showing the (incomplete) windings. In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [1]

  5. Traction motor - Wikipedia

    en.wikipedia.org/wiki/Traction_motor

    The DC motor was the mainstay of electric traction drives on electric and diesel-electric locomotives, street-cars/trams and diesel electric drilling rigs for many years. It consists of two parts, a rotating armature and fixed field windings surrounding the rotating armature mounted around a shaft.

  6. DC motor - Wikipedia

    en.wikipedia.org/wiki/DC_motor

    A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.

  7. Field coil - Wikipedia

    en.wikipedia.org/wiki/Field_coil

    The field coils can be mounted on either the rotor or the stator, depending on whichever method is the most cost-effective for the device design. In a brushed DC motor the field is static but the armature current must be commutated, so as to continually rotate

  8. Brushed DC electric motor - Wikipedia

    en.wikipedia.org/wiki/Brushed_DC_electric_motor

    A DC motor's speed and torque characteristics vary according to three different magnetization sources, separately excited field, self-excited field or permanent-field, which are used selectively to control the motor over the mechanical load's range. Self-excited field motors can be series, shunt, or a compound wound connected to the armature.

  9. Compensation winding - Wikipedia

    en.wikipedia.org/wiki/Compensation_Winding

    A compensation winding in a DC shunt motor is a winding in the field pole face plate that carries armature current to reduce stator field distortion.Its purpose is to reduce brush arcing and erosion in DC motors that are operated with weak fields, variable heavy loads or reversing operation such as steel-mill motors.
