Problems solved by technology

However, due to the limitation of the inlet of cooling water and the need for a long running route for the cooling water channel to cover the entire motor, the heat dissipation of the motor near the exit is poor, and the heat dissipation of each part of the motor is uneven.

Abstract

A multi-channel water-cooling heat dissipation system of a direct current brushless motor comprises a motor body, the motor body comprises a machine shell and a stator assembly installed in the machine shell, a circular liquid path ring is installed between the machine shell and the stator assembly, and a water inlet and a water outlet of the circular liquid path ring are both communicated with an external water tank; and a plurality of annularly arranged water channels are uniformly distributed on the outer surface of the circular liquid path ring, and each water channel is provided with an independent water inlet and an independent water outlet. Multi-channel heat dissipation is arranged, the heat dissipation efficiency is improved, and the temperature of the motor is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a multi-channel water-cooling heat dissipation system for a DC brushless motor. Background technique [0002] A permanent magnet brushless motor is a permanent magnet motor that is commutated or current controlled by an electronic circuit. There are two types of permanent magnet brushless motors, sine wave drive and square wave drive. A permanent magnet motor driven by a sine wave is called a permanent magnet AC servo motor, and a permanent magnet motor driven by a square wave is called a brushless DC motor. Because of its excellent performance, brushless DC motors are widely used in various electronic equipment or appliances, such as tape recorders, record players, electric massagers, computer hard drives, optical drives and various toys, and are also widely used in automobiles and motorcycles. , shipbuilding, aviation, machinery and other industri...
