Permanent magnet synchronous motor convenient to install

Abstract

The invention discloses a permanent magnet synchronous motor convenient to install. The motor comprises a housing, a first transmission gear group, a rotor, a stator and an output shaft. The stator is fixedly arranged in the housing; the outer circular ring area of the rotor is equipped with a plurality of permanent magnets; the rotor is rotatably arranged in the middle portion of the stator; the rotor is in transmission connection with the first transmission gear group through a first gear; the lower end of the output shaft is in transmission connection with the first transmission gear group through a second gear; the upper end of the output shaft protrudes out of one surface of the housing; and the output shaft and the rotor are in coaxial arrangement. The motor can be arranged coaxially, is smaller in occupied installation space, eliminates limitation in the aspects of assembly and design layout, has higher flexibility, and meets installation and use under the small installation space.

Description

technical field [0001] The invention relates to the technical field of permanent magnet synchronous motors, in particular to an easy-to-install permanent magnet synchronous motor. Background technique [0002] In the prior art, the permanent magnet synchronous motor has low cost and high torque, and the permanent magnet synchronous motor also has many defects, so its application is subject to many restrictions. [0003] The permanent magnet synchronous motor is equipped with a reduction transmission gear inside, including a housing, a rotor, a stator, a reduction transmission gear and an output shaft. The rotor is fixed with a number of permanent magnets, and the outer edge of the rotor is wound with coils. The rotor is rotatably installed in the inner cavity of the stator. The rotor is fixed in the casing, the rotor is connected to the reduction transmission gear through the gear, the reduction transmission gear is connected to the output shaft, and the output shaft protrud...

Problems solved by technology

[0006] On the other hand, for the permanent magnet synchronous motor whose output shaft is offset to one side of the shaft center, this structural design also restricts the position layout of the permanent magnet synchronous motor and the external transmission mechanism in the installation space, and the flexibility in space layout Poor, on the one hand, it brings great obstacles to the structural design, on the other hand, it increases the difficulty of the assembly process of the mass-produced production line, makes the assembly efficiency low, and the stability of the transmission after the assembly of the finished product is also deviated, so it is necessary be improved
