Shaft and commutator for DC motor for K mechanism

Mar 12, 2019

The role of the DC motor in the K mechanism is to generate electromagnetic torque and induced electromotive force. It is a key component of the DC motor for energy conversion, so it is called an armature. It is made up of a number of coils (hereinafter referred to as components) connected according to a certain rule. The coil is wound with high-strength enameled wire or glass-coated flat copper wire. The coil sides of different coils are embedded in the armature slot in two layers, the coil and The insulation between the cores and between the upper and lower coil sides must be properly insulated. In order to prevent the centrifugal force from pulling out the edge of the coil, the notch is fixed by the wedge. The terminating portion of the coil extending beyond the slot is tied with a thermosetting, non-woven glass ribbon.

Commutator for DC motor for K mechanism

In the DC motor, the commutator is equipped with a brush, which can convert the external DC power into an alternating current in the armature coil, so that the direction of the electromagnetic torque is constant; in the DC generator, the commutator is equipped with The brush can convert the alternating electromotive force induced in the armature coil into a direct current electromotive force drawn from the positive and negative brushes. The commutator is a cylinder composed of a plurality of commutator segments, and the commutator segments are insulated by mica plates.

Rotating shaft of DC motor for K mechanism

The rotating shaft plays a supporting role for the rotation of the rotor, and requires a certain mechanical strength and rigidity, and is generally processed by round steel.

A direct current generator is a machine that converts mechanical energy into direct current electrical energy. It is mainly used as a DC motor, electrolysis,

DC motors required for electroplating, electrosmelting, charging, and excitation power of alternators.
