Permanent magnet direct current (DC) speed-reducing motor

Abstract

The invention discloses a permanent magnet direct current (DC) speed-reducing motor, which comprises a rotor, a stator arranged at the periphery of the rotor, a speed reducer connected to an output end of the rotor, and a commutator, wherein the rotor comprises a motor spindle and a rotor core which is arranged on the motor spindle; a plurality of grooves which are distributed along the length direction of the rotor core are formed on a peripheral wall of the rotor core; a winding is arranged at the periphery of the stator; a plurality of permanent magnets are arranged on the stator; the motor spindle is provided with a first end and a second end; the commutator is arranged at the second end; an electric brush mechanism is arranged on the commutator; and both ends of the stator are provided with an end cover which is fixed with the stator. Due to the integrated design of transmission, speed reduction, brake and manually fine tuning of the spindle of the permanent magnet DC speed-reducing motor, the motor can be better matched with equipment; due to the self-pressing design of the electric brush mechanism in the permanent magnet DC speed-reducing motor, commutation is guaranteed, and the motor operates without any fault for a long time; and the motor is compact in structure, small in volume, low in vibration and noise and suitable for popularization in industries.

Description

technical field [0001] The invention relates to a permanent magnet motor, in particular to a permanent magnet direct current geared motor. Background technique [0002] The permanent magnet DC motors in the prior art, due to the long magnetic flux path, lead to a large core loss, and most of them are complex in structure, large in size, high in noise, and low in performance, and are not suitable for applications in demanding occasions. Most of the brushes in permanent magnet motors are not adjustable, which leads to large changes in contact voltage drop, which can easily cause safety accidents. Contents of the invention [0003] The purpose of the present invention is to provide a small volume, high efficiency and energy saving permanent magnet direct current geared motor. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A permanent magnet DC deceleration motor, ...
