Embodiment Construction

[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the present invention is a special motor for miniature circuit breakers, including a permanent magnet motor 13 and a reduction box connected with the permanent magnet motor 13 .

[0021] The motor shaft of the permanent magnet motor 13 is fixedly connected with a motor gear 12 . The connection mode of motor gear 12 is: as Figure 6 Shown, on the motor shaft of permanent magnet motor 13, be provided with flat square 21 and bead 22, the inner hole of motor gear 12 (see Figure 7 ) corresponds to the cross-sectional shape of the motor shaft, and the motor shaft is closely matched with the inner hole of the motor gear 12 . Using this connection method, there is no key and pinless connection, which is more convenient and economical.

[0022] The gearbox can be a single-stage gearbox or a multi-stage gearbox, ...

Abstract

The invention relates to a motor specially used for a miniature circuit breaker. The motor comprises a permanent magnet motor and a reduction gearbox connected to the permanent magnet motor, wherein a motor gear is fixedly connected to a motor shaft of the permanent magnet motor, and meshed with an input gear of the reduction gearbox, the gear shaft of the input gear is fixedly connected to a box body of the reduction gearbox, the input gear is meshed with an output gear, the output gear is fixedly connected to an output gear shaft, and the output gear shaft can be rotatably fixed on the box body of the reduction gearbox. As the permanent magnet motor in the invention is provided with the motor gear which is provided with the input gear of the reduction gearbox, and the gear shaft of the reduction gearbox is directly fixed on the box body, therefore, the structure is compact, the whole volume of the motor is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to an electric operating mechanism of a miniature circuit breaker, in particular to a special motor for a miniature circuit breaker. Background technique [0002] At present, the electric operation, remote control and intelligent control of small power circuit breakers below 200A are developing rapidly, and the special motor for miniature circuit breakers is the core basic component to realize its functions. The electric operation, remote control and intelligent control technology of the existing frame power circuit breaker are relatively perfect, but its structure is relatively large; match. Contents of the invention [0003] In view of the above problems, the present invention provides a special motor for miniature circuit breakers. The motor is simple in structure, small in size and low in cost, and can meet the requirements of electric operation, remote control and intelligent control of small power circuit breakers below 2...
