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. 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.

4. 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.

5. Field coil - Wikipedia

   en.wikipedia.org/wiki/Field_coil

   Most [note 1] DC field coils generate a constant, static field. Most three-phase AC field coils are used to generate a rotating field as part of an electric motor. Single-phase AC motors may follow either of these patterns: Small motors are usually universal motors, like the brushed DC motor with a commutator, but run from AC.

6. 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]

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.
