  2. Armature (electrical) - Wikipedia

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

    Armature reaction is essential in amplidyne rotating amplifiers. Armature reaction drop is the effect of a magnetic field on the distribution of the flux under main poles of a generator. [5] Since an armature is wound with coils of wire, a magnetic field is set up in the armature whenever a current flows in the coils.

  3. V curve - Wikipedia

    en.wikipedia.org/wiki/V_curve

    In synchronous machines, the V curve (also spelled as V-curve) is the graph showing the relation of armature current as a function of field current in synchronous motors keeping the load constant. The name comes from an observation made by W. M. Mordey in 1893 that the curve resembles a letter V. [1]

  4. Armature Controlled DC Motor - Wikipedia

    en.wikipedia.org/wiki/Armature_Controlled_DC_Motor

    The stator consists of field windings while the rotor (also called the armature) consists of an armature winding. [4] When both the armature and the field windings are excited by a DC supply, current flows through the windings and a magnetic flux proportional to the current is produced. When the flux from the field interacts with the flux from ...

  5. 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.

  6. Motor constants - Wikipedia

    en.wikipedia.org/wiki/Motor_constants

    where is the armature current of the machine (SI unit: ampere). is primarily used to calculate the armature current for a given torque demand: = The SI units for the torque constant are newton meters per ampere (N·m/A).

  7. Brushed DC electric motor - Wikipedia

    en.wikipedia.org/wiki/Brushed_DC_electric_motor

    When power is first applied to a motor, the armature does not rotate, the counter EMF is zero and the only factor limiting the armature current is the armature resistance. [19] As the prospective current through the armature is very large, the need arises for an additional resistance in series with the armature to limit the current until the ...

  9. Shaft voltage - Wikipedia

    en.wikipedia.org/wiki/Shaft_voltage

    DC machines may have leakage current from the armature windings that energizes the shaft. Currents due to shaft voltage causes deterioration of motor bearings, but can be prevented with a grounding brush on the shaft, grounding of the motor frame, insulation of the bearing supports, or shielding.
