Direct-current driving permanent magnet variable frequency motor

Abstract

The invention relates to the technical field of direct current motors, in particular to a direct current drive permanent magnet variable frequency motor. The motor comprises a main shell, a rear cover, a stator and a rotor; a front retainer is arranged at the front end of the main shell, a rear retainer is arranged on the rear cover, the two ends of the rotor are rotationally inserted between the front retainer and the rear retainer respectively, and a dustproof net is arranged on the rear cover. At least three L-shaped rods are evenly installed on the inner wall of the main shell, each L-shaped rod is rotationally sleeved with a driven gear and a fan, the driven gears are detachably connected with the fans, and driving gears meshed with the driven gears are installed on the rotor. Heat dissipation is provided through the multiple fans, the rotor is used for driving all the fans to rotate, each fan is detachably connected to the driven gear, rapid disassembly and assembly are achieved through the protruding rods, after the fans start to rotate, the protruding rods enter the clamping holes under the action of centrifugal force to clamp the fans and the driven gears, the disassembly and assembly process is facilitated, and the fan cannot fall off during working, so convenience and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of DC motors, in particular to a DC-driven permanent magnet variable frequency motor. Background technique [0002] A DC motor is a rotating electrical machine that converts DC electrical energy into mechanical energy (DC motor) or converts mechanical energy into DC electrical energy (DC generator). It is a motor that can convert DC electric energy and mechanical energy into each other. When it operates as a motor, it is a DC motor, which converts electrical energy into mechanical energy; when it operates as a generator, it is a DC generator, which converts mechanical energy into electrical energy. [0003] Existing patent (notification number: CN108599433B) a permanent magnet DC drive variable frequency motor, including a motor base, a rotating shaft and a casing, the rotating shaft is fixed inside the motor base and one end of the rotating shaft passes through the motor base One side of the surface, the ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a DC-driven permanent magnet variable frequency motor to solve the problem that it is still inconvenient to remove the end cover to clean the motor fan proposed in the above background technology, and the problem that the motor heating is likely to be aggravated if the cleaning is not timely
