Novel brushless doubly-fed motor with efficient heat dissipation

Abstract

The invention discloses a novel efficient heat dissipation brushless doubly-fed motor. The novel efficient heat dissipation brushless doubly-fed motor comprises a motor shell, an overhaul groove is formed in one end of one side of the outer wall of the motor shell, a coil assembly is arranged in the motor shell in a clamped mode, and a protective sponge is arranged at the position, located on the outer wall of the coil assembly, of the inner wall of the motor shell in a clamped mode; and an arc-shaped protective cover is hinged to the outer edge of one side of the inner wall of the overhauling groove, a first through groove is formed in the middle of one side of the arc-shaped protective cover, and a first heat dissipation net is clamped to the inner wall of the first through groove. According to the novel efficient heat dissipation brushless doubly-fed motor, the arc-shaped protective cover is rotated to shield and seal the maintenance groove, the protective sponge plays a role in damping and protection during operation of the motor, heat of the upper end and the lower end of the inner wall of the motor shell can be discharged under the action of the first heat dissipation net and the second heat dissipation net, and the risk that the motor is damaged due to high temperature is reduced, so that the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of doubly-fed motors, in particular to a novel high-efficiency heat dissipation brushless doubly-fed motor. Background technique [0002] The traditional doubly-fed motor is mainly used in industrial production to drive the output end of large-scale production machines, and the doubly-fed generator, also known as AC excitation generator, AC excitation technology is an advanced power generation and speed regulation Drive technology, generators or motors using this technology are collectively referred to as AC excitation motors. With the development of modern technology, the frequency of use of such doubly-fed motors is gradually increasing; [0003] In the prior art, when designing and manufacturing the high-efficiency heat dissipation brushless doubly-fed motor, most designers will pay attention to the stability of the internal drive of the design device to reduce the power of the inner wall, thereby reducin...

Problems solved by technology

[0003] In the prior art, when designing and manufacturing the high-efficiency heat dissipation brushless doubly-fed motor, most designers will pay attention to the stability of the internal drive of the design device to reduce the power of the inner wall, thereby reducing the heat generated inside the motor, but in the motor If the upper end does not have a heat dissipation structure that is easy to disassemble, when the motor generates high temperature, the staff cannot open it for maintenance, which will affect the use of the motor and reduce the service life of the device
