Permanent magnet double-reduction motor

Abstract

The invention relates to a motor, in particular to a permanent magnet double-reduction motor which belongs to the mechanical field. The permanent magnet double-reduction motor comprises a stator assembly, an armature assembly and a rear cover. The permanent magnet double-reduction motor is characterized in that: the permanent magnet double-reduction motor further comprises a planetary reducer mechanism I and a planetary reducer mechanism II, the armature assembly is connected with the planetary reducer mechanism I through a bearing base, and the planetary reducer mechanism II is arranged on the planetary reducer mechanism I. The reducing mechanisms of the motor are the two-stage planetary reducer mechanisms and can simultaneously output two torques, thereby improving the applicability of the motor; simultaneously, the motor has small motor volume, stable performance, low noise, small no-load current and great braking torque. The motor has the advantages of a permanent magnet direct current motor, simultaneously has the advantages of a reduction motor and a direct-driven motor and can output the different torques to achieve multiple purposes of one machine, thereby overcoming the problem of small torque of the existing direct current permanent magnet direct-driven motor.

Description

technical field [0001] The invention relates to a motor, in particular to a permanent magnet double-reduction motor, which belongs to the field of machinery. Background technique [0002] At present, advanced motorcycle starters use electromagnetic switches or direct-drive starters; most of them are geared motors with electromagnetic switches, and their output torques generally range from 15-20N.m, and direct-drive starters generally range from 5-14N. m, but they are less than 40N.m, and they are large in size and noisy. The output torque of the permanent magnet DC starter is smaller, and it can reach 6---10N.M after the first-stage deceleration. Simple structure, small size, light weight, low noise and low power. However, it is very common for domestic motorcycles to adopt the permanent magnet direct drive starting method, and the output torque is mostly less than 2N.m. my country is a big motorcycle consumption country and a big motorcycle production country. The market ...

Problems solved by technology

The shortcomings of the above-mentioned motors are that firstly, the motor power is small, and secondly, only one kind of torque can be output, so the applicability is narrow
