Problems solved by technology

The traditional implementation methods can be divided into two categories: one is to output bidirectional torque through a special mechanical structure, but adding redundant structures will reduce the overall efficiency of the system; the other is to achieve bidirectional output by increasing the number of motors, but this will be extremely Greatly increase system weight and footprint

Embodiment 1

[0033] see Figure 1~Figure 5 , the pair of turntable motors includes a fusion shaft structure (I), an integrated casing structure (II) and a support bearing (102), and is characterized in that: the fusion shaft structure (I) is composed of windings of each phase (105~107) The inner end is connected to the external brush slip ring (109, 113) for power supply through the shaft groove (110~112); meanwhile, the integrated shaft structure (I) is contained in the integrated casing structure (II) and supported by the supporting bearing (102) support; the integrated casing structure (II) is connected with the casing (201) by the outer end of the permanent magnet (202); the integrated shaft structure (I) winding and the integrated casing structure (II) permanent magnets are mutually The electromagnetic force generated by the action drives the two to move in opposite directions, realizing the counter-rotation function of the disc motor, which can realize bidirectional power output, and...

Embodiment 2

[0034] Embodiment two, this embodiment is basically the same as embodiment one, and the special features are as follows:

[0035] The phase winding fixing method of the integrated rotating shaft structure (I) includes but is not limited to, the winding is embedded in the rotating shaft (101) to fix; or the outer layer of the winding is covered with support material and fixed to the rotating shaft (101); or the winding is fixed by bonding material Fixed with the shaft. The supporting material used for winding fixation: including but not limited to, using carbon fiber or aramid fiber high-strength material to weave, or bind, or wrap, etc. to fix and increase the structural strength. The rotating shaft (101) in the integrated rotating shaft structure (I): including but not limited to, grooves on the surface or inside of the rotating shaft (101) to provide physical connection channels between windings of each phase and external circuits. The integrated casing structure (II) is co...

Embodiment 3

[0037] Figure (2) shows the integrated rotating shaft structure in the implementation example of the present invention, which is composed of a slotted rotating shaft (401) and windings (105~107) of each phase.

[0038] Further, the rotating shaft involved in the examples of the present invention may have one or more grooves on the surface or inside. The polyphase wires drawn out from the winding are connected to the brush slip ring outside the rotating shaft along the groove, and the inner surface of the groove can be coated with insulating material (108) to enhance the insulation level between the groove of the rotating shaft and the winding. The outer surface of the thread-embedded shaft can use high-strength materials such as carbon fiber and aramid fiber (103, 104) to increase the structural strength by covering, binding, etc., and reduce the risk of strength decline caused by the slotting of the shaft.

[0039] Based on the large effective diameter of the inner end of the...

Abstract

The invention discloses a rotation disc-type motor structure. The rotation disc-type motor structure comprises a fusion-type rotation shaft structure (I), an integrated enclose mechanism (II) and a support bearing (102) and is characterized in that the fusion-type rotation shaft structure (I) is in a way that an inner end part of each phase winding (105-107) is connected with a shaft outer brush sliding ring (109, 113) through a rotation shaft groove passage (110-112), meanwhile, the fusion-type rotation shaft structure (I) is contained in the integrated enclosure structure (II) and is supported by the support bearing (102), and the integrated enclosure structure (II) is in a way that an outer end part of the permanent magnet (202) is connected with an enclosure (201). The fusion-type rotation shaft structure (I) and the integrated enclosure structure (II) are driven to move towards an opposite direction by an electromagnetic force generated by a mutual effect of the fusion-type rotation shaft structure (I) and the permanent magnet of the integrated enclosure structure (II), the opposite rotation function of the disc-type motor is achieved, and bidirectional power output can be achieved; and moreover, the rotation disc-type motor structure has higher opposite rotational speed, the power density the motor is easily improved, dispersed power output can be achieved, the strength demand of the rotation shaft is reduced, and the universality of the motor is improved.

Description

technical field [0001] The invention belongs to a motor with optimized design of motor topology structure, and in particular relates to a paired turntable motor. Background technique [0002] The stator part of a traditional motor is mainly composed of armature windings, stator cores, etc.; the rotor part is mainly composed of permanent magnets, rotor cores, etc.; the shaft is mainly used to drag specific loads, install position sensors, etc.; the casing is generally used to fix connect. [0003] According to the direction of magnetic flux, motors can be divided into radial flux motors and axial flux motors. The magnetic force lines of the radial flux motor are perpendicular to the air gap plane, and the magnetic force lines are along the radial direction; the magnetic force lines of the axial flux motor are parallel to the air gap plane, and the magnetic force lines are along the axial direction, and the shape of the axial flux motor is usually a disc, called a disc motor...
