Abstract

The invention relates to the field of motors, and specifically relates to an easy-to-clean brush type alternating-current motor. The motor comprises a motor shell, a stator, a rotor, a motor spindle, and a fan. The motor further comprises a brush cover, an insulating sleeve, a slip ring, a brush rod, brushes, a brush cleaning device, a temperature sensor, a support seat, and a contact position sensor. The slip ring is fixedly connected to the insulating sleeve. The insulating sleeve is fixedly connected to the motor spindle. The brush rod is fixedly connected to the upper part of the inner side of the brush cover. The three brushes are uniformly mounted on the brush rod at equal intervals. The brush cleaning device is disposed on the upper part of the brush cover. The support seat and the contact position sensor are disposed on the lower part of the brush cover. The easy-to-clean brush type alternating-current motor is humanized in design, convenient to operate, and labor-saving. The incidence of electric sparks is reduced.

Description

technical field [0001] The invention relates to the field of motors, in particular to an easy-to-clean AC motor. Background technique [0002] The carbon brush of the motor and the carbon brush of the generator are also collectively referred to as the carbon brush of the motor or the brush of the motor. The carbon brush of the motor looks a bit like the rubber strip of a pencil, and there are wires leading out from the top, and the volume is large or small. [0003] However, the wire-wound carbon brushes used on motors often have sparks, which can easily cause accidents and burn the motor. The reason why the carbon brush will spark is: [0004] When we use the carbon brushes of wound motors, due to the continuous wear of the carbon brushes during long-term operation, the contact surface is uneven, the pressure of the carbon brush is not enough or the slip ring is not round, and there is oil on the bearing. Drops or other debris falling between the slip ring and the carbon ...
