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. Traction motor - Wikipedia

   en.wikipedia.org/wiki/Traction_motor

   The commutator collects all the terminations of the armature coils and distributes them in a circular pattern to allow the correct sequence of current flow. When the armature and the field windings are connected in series, the whole motor is referred to as "series-wound". A series-wound DC motor has a low resistance field and armature circuit.

5. 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 ...

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]

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
