Problems solved by technology
[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 brush, etc., will cause the carbon brush to emit sparks

The invention relates to the field of motors, specifically a portable anti-spark motor, including a motor housing, a stator, a rotor, a motor shaft and a fan; the invention also includes a brush cover, an insulating sleeve, a slip ring, a brush rod, Brushes, brush cleaning devices and temperature sensors; the slip ring is fixedly connected to the insulating sleeve, the insulating sleeve is fixedly connected to the motor shaft, and the brush rod is fixedly connected to the inner upper part of the brush cover, Three electric brushes are evenly installed on the brush rod at equal intervals, and the brush cleaning device is located on the upper part of the brush cover. The invention is humanized in design, convenient in operation, saves manpower, and reduces the probability of electric sparks occurring.
Description
technical field [0001] The invention relates to the field of motors, in particular to a portable anti-spark 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 carbo...
