Abstract

The invention belongs to the field of commutators, and particularly discloses an anti-creeping hook type commutator with a mica ring and a using method thereof, the commutator comprises a commutator hook (110), a commutator segment (120), a trapezoidal foot (130), a bakelite layer (140), a hollow tube (150), the mica ring (160) and a hollow tube opening (170); according to the anti-creeping hook type commutator with the mica ring, creeping can be effectively prevented, jumping and flying of the commutator segment are prevented, and the service life of the commutator is prolonged.

Description

technical field [0001] The invention belongs to the field of commutators, and specifically discloses a leakage-proof electric hook commutator with a mica ring and a use method thereof. Background technique [0002] As an indispensable and important basic equipment in industry, transportation, national defense and daily life, the motor's downstream industries include almost all basic industries of the national economy. As one of the core components of the motor, the commutator is also growing with the development of the motor industry. The commutator mainly has specifications such as hook type, groove type and plane type. Structurally, the commutator is a circle surrounded by several contact pieces, which are respectively connected to each contact on the rotor. The two electrodes connected to the outside are called brushes, and only two of them are in contact at the same time. The principle is that when the coil passes through the current, it will rotate through the attract...
