COMPONENTS

ARMATURE COILS

A brushed DC motor has a set of rotating windings wound on an armature mounted on a rotating shaft. The shaft also carries the commutator a long-lasting rotary electrical switch that periodically reverses the flow of current in the rotor windings as the rotor bar rotates. Thus, every brushed DC motor has AC flowing through its rotating windings. Current flows through one or more pairs of brushes that bear on the commutator; the brushes connect an external source of electric power to the rotating armature.

MICA V-RINGS

Mica V-rings or cones is made of hot moulding mica sheets of B or H class, it is pressed
by mould under heat. Mica V-rings or cones is uniform in thickness, no delamination,
it is used as commutators insulation of railway traction motors, HV explosion – proof
motors and DC motors.

BRUSH GEARS, BRUSH ARMS AND BRUSH BOXES

A commutator consists of a set of copper segments, fixed around the part of the circumference of the rotating machine, or the rotor, and a set of spring-loaded brushes fixed to the stationary frame of the machine.

COMMUTATOR

A Commutator is a rotary electrical switch in DC electric motors or electrical generators that periodically reverses the current direction between the rotor and the external circuit. In a motor, it applies power to the best location on the rotor, and in a generator, picks off power similarly.

ROTOR BARS

A brushed DC motor has a set of rotating windings wound on an armature mounted on a rotating shaft. The shaft also carries the commutator a long-lasting rotary electrical switch that periodically reverses the flow of current in the rotor windings as the rotor bar rotates.

SLIP RINGS

The slip ring is an electric transmission device that allows energy flow between two electrical rotating parts, such as in a motor. The slip ring is designed to carry current or signals from a stationary wire into a rotating device. It consists of a metal brush which rubs on the outside diameter of a rotating metal ring.
