Embodiment Construction

[0027] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0028] Please see Figure 1-9 , the application provides a dual direct-drive hybrid vernier actuator motor structure, which includes:

[0029] A disc stator 1 includes a first stator structure and a second stator structure arranged opposite to each other, a first winding 2 is wound on the first stator structure, a second winding 3 is wound on the second stator structure, and the disc stator is specifically It is a double-sided slotted disc structure. The number of slots corresponds to the operating principle of permanent magnet motors and / or vernier motors. The number of pole pairs of the stator and rotor of the permanent magnet motor is the sa...

Abstract

The invention provides a double-direct-drive hybrid vernier actuator motor structure, which comprises a disc stator arranged in a shell, a first stator structure and a second stator structure which are arranged oppositely, a first winding is wound on the first stator structure, and a second winding is wound on the second stator structure; the first permanent magnet is arranged on one side of the first stator structure, the first permanent magnet is connected with a first rotor shaft extending out of the right side of the machine shell, a first bearing is arranged between the first rotor shaft and the disc type stator, and a second bearing is arranged between the first rotor shaft and the machine shell; the second permanent magnet is arranged on one side of the second stator structure, the second permanent magnet is connected with a second rotor shaft extending out of the left side of the machine shell and / or the second permanent magnet is connected with a third rotor shaft extending out of the right side of the machine shell, a third bearing is arranged between the second rotor shaft and the disc type stator, and a fourth bearing is arranged between the second rotor shaft and the machine shell. And a fifth bearing is arranged between the third rotor shaft and the first rotor shaft.

Description

【Technical field】 [0001] The invention relates to the field of permanent magnet motors, in particular to a motor structure of a double direct drive hybrid vernier actuator. 【Background technique】 [0002] There are more and more types of robots in modern industrial applications, and their functions are becoming stronger and stronger. But with the development of technology, one part of the robot has rarely changed, and this part is the actuator. Most robots and robotic arms use electric motors connected to gearboxes to form an actuator module to drive external components such as wheels, chassis, and joints. This type of actuator module usually uses a high-speed motor to cooperate with a high-reduction ratio reducer to obtain a relatively large instantaneous torque. This relatively mature result also exposed some obvious flaws. First, the volume of the gearbox with a high reduction gear ratio is usually large, which makes the overall volume and weight of the actuator module...
