Embodiment Construction

[0018] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0019] As shown in the figure, the main embodiment of a spherical motor of the present invention is mainly composed of an annular seat 1, a spherical mover 2, a mover connecting body 6, a long arc stator 3, a second long arc stator 4, and a short arc stator 5 , 7 components of drag reducing balls. Wherein the long arc stator 3 is arranged along the diameter in the direction of the top view, and the second long arc stator 4 and the short arc stator 5 are arranged on both sides of the long arc stator 3 at equal intervals in the top view direction, and the second long arc stator 4 and the short arc stator are arranged at equal intervals in the top view direction. There are 6 and 8 arc stators 5 respectively. The long-arc stator 3 includes an iron core 31 with slots, and a multi-phase (two-phase, three-phase or more) coil 32 embedded in the slots. Spheric...

Abstract

The invention relates to a spherical motor, which comprises an annular base 1, a spherical rotor 2, rotor connectors 6, a long circular arc stator 3, secondary long circular arc stators 4, short circular arc stators 5 and resistance reducing balls 7, wherein the long circular arc stator 3, the secondary long circular arc stators 4 and the short circular arc stators 5 are connected with the annular base 1 through the rotor connectors 6 so as to form an integral whole. The invention belongs to the technical field of motors. The spherical motor, which is different from an existing arc-type stator motor and capable of realizing random-direction turning of the secondary rotor within 360 degrees, is provided through designing a new type of structure based on fundamental principles of an arc-type linear induction motor. The spherical motor can be applied to various occasions of universal moving, for example, the spherical motor acts as a vehicle wheel so as to enable a vehicle to travel easily in a 360-degree mode, and the vehicle wheel structure is simplified.

Description

technical field [0001] The invention relates to a multi-degree-of-freedom spherical motor, which belongs to the technical field of motors. Background technique [0002] The current round-wheeled vehicles can only travel in one direction, and need to use a steering mechanism to realize the steering. The structure is complicated, and the rotation angle is limited, so it is impossible to realize 360-degree travel. For example, in a crowded parking space, cars must go through cumbersome forward and backward movements to park in the parking space, which wastes time and requires the driver to have superb driving skills. At the same time, the distance between cars is relatively large, wasting precious parking space. [0003] The arc-shaped stator motor is a typical disc-shaped linear motor, which makes the primary arc-shaped and placed outside the secondary cylindrical surface, also known as the arc-shaped primary cylindrical secondary linear motor. Although the disc-type linear m...
