Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a segmented stator, a manufacturing method thereof, and a motor. Background technique [0002] It is pointed out in the related art that the speed regulation method of the motor generally adopts the auxiliary winding tap method and the capacitor speed regulation method. The tap method of the auxiliary winding is mainly to achieve the purpose of speed regulation by changing the size and ellipticity of the air gap magnetic field of the motor. However, the tap method of the auxiliary winding has the following defects: in order to realize N' gear speed regulation, the motor must make N'-1 taps, and it needs to pass N' cross-river lines in the process. The more the number of wires, the lower the production efficiency. At the same time, because each cross-river line is connected by the wire-passing column on the winding frame, each cross-river line is close to each other, ...

Problems solved by technology

However, the tap method of the auxiliary winding has the following defects: in order to realize N' gear speed regulation, the motor must make N'-1 taps, and it needs to pass N' cross-river lines in the process. The more lines there are, the lower the production efficiency is generally. At the same time, because each cross-river line is connected by the wire-passing column on the winding frame, each cross-river line is close to each other, and there is a hidden danger of inter-turn short circuit.

However, the cost of capacitor speed regulation is high, and at the same time, it is necessary to increase the process of capacitor wiring

At present, many manufacturers use these two methods in combination. Generally, 8-speed speed regulation can be achieved. Motors higher than 8-speed are difficult to achieve in terms of manufacturing process, and the cost is relatively high.
