Stator structure

A stator structure, in particular, a stator structure that can be applied to a pole-changing motor.

The existing motor should have a stator, a rotor and a brush. The function of the brush is to conduct current between the stator and the rotor.

However, the existing motor still has its shortcomings in practical applications, so the pole-changing motor is generated according to the requirement, and the pole-changing motor is changed by the number of poles of the pole-changing motor by an electronic frequency converter.

Although the frequency conversion motor can replace the existing motor in practical application, the electronic frequency converter is an electronic device, the electronic device will be damaged due to some unknown factors, and the components of the frequency conversion motor are still too complicated. Therefore, the inverter motor still has room for discussion.

In one embodiment, the technical means of the present disclosure is to provide a stator structure including: a certain sub-disc; two electric brush discs respectively disposed at one end of the stator disc; and two turntables, each of which is disposed in each The brush disc is away from the side of the stator disc, each turntable has at least one first pole winding and at least one second pole winding, and the first pole winding or the second pole winding can be selectively electrically coupled Connect the brush tray.

Each of the brush disks 2 is disposed at each end of the stator disk 1. Each of the brush disks 2 has a plurality of brush grooves 20 and a plurality of brushes 21, and each of the brushes 21 is disposed in each of the brush grooves 20.

The brush 21 is a conductive material. For example, the conductive material is carbon brush, copper or graphite, but is not limited.

Each of the turntables 3 is disposed on a side of each of the brush disks 2 away from the stator disk 1. Each turntable 3 has at least one first pole winding 30 and at least one second pole winding 31, and the number of poles of the first pole winding 30 For example, in the present embodiment, the number of poles of the first pole winding 30 is 4 poles, and the number of poles of the second pole winding is 2 In the pole, and in practical applications, the number of poles of the first pole winding 30 may also be 8 poles or 6 poles, and the pole set of the second pole windings is 4 poles, 3 poles or 2 poles.

The first pole winding 30 is a concentrated winding (Concentrated Winding), the second pole winding 31 is a distributed winding, and the first pole winding 30 and the second pole winding 31 are selective. Electrically coupled to the brush 21, as exemplified above, if the number of poles of the first pole winding 30 is 4 poles and the number of poles of the second pole winding is 2 poles, the motor of the present disclosure is applied as the first pole The number of windings 30 is electrically coupled to the brush 21, and the motor is a 4-pole motor. If the second pole winding 31 is electrically coupled to the brush 21 and the motor is a 2-pole motor, the number of poles of the motor is first The pole winding 30 is determined by the second pole winding 31. When the turntable 3 is rotated by a specific angle, the first pole winding 30 is electrically coupled to the brush 21 of the brush disk 2, and the second pole winding 31 is electrically coupled to the brush 21, and when the turntable 3 is After being rotated to another specific angle, the first pole winding 30 is electrically coupled to the brush 21 of the brush disk 2, and the first pole winding 30 is not electrically coupled to the brush 21.

As described above, the brush disk 2 is disposed between the turntable 3 and the stator disk 1, so that the brush disk 2 can be selectively coupled to the stator disk 1, or the brush disk 2 can be selectively coupled to the turntable 3.

Referring to FIG. 3 again, each of the rotating units 40 is disposed on a side of each of the rotating discs 3 remote from each of the brush discs 2, and each of the rotating units 40 is coupled to each of the rotating discs 3 to rotate each of the rotating discs 3 by an angle.

Referring to FIG. 4, in one embodiment, the present disclosure is a stator structure. The positions of the two brush discs 2 and the two rotating discs 3 on the stator disc 1A are as described above, and the brush discs 2 and Each of the turntables 3 is as in the above-described embodiment, so that the component symbols follow the above-described embodiments.

In this embodiment, the stator disk 1A has a plurality of inductive component slots 10A, and each of the inductor component slots 10A has an inductive component 11A. The inductive component 11A is an inductive piece, and the inductive piece is a metal piece. The line of the wire, so the inductor is like the wire winding described above.

In summary, the rotating unit is a mechanical component, so that the electronic device can be prevented from being damaged due to some unknown factors, and the amount of the wire can be saved, and the wire is made of copper wire.

In addition, the motor of the present disclosure is a variable pole induction motor. The disclosure is to selectively electrically couple the brush disk by the pole set of the first pole number winding and the second pole number winding to change the motor. The number of poles eliminates the need for a more complex and easily damaged electronic frequency converter, which simplifies the motor structure and reduces energy consumption and weight and cost.

However, the specific embodiments described above are only used to illustrate the disclosure, and are not intended to limit the scope of the disclosure, and may be disclosed without departing from the spirit and scope of the disclosure.
