Embodiment Construction

[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] An embodiment of the present invention provides a motor stator, the motor stator includes a winding, the winding includes: a plurality of coils; a relay switch, connected between one or more of the plurality of coils, used to reduce the Resistance of multiple coils.

[0022] In this embodiment, since the resistance of multiple coils in the motor stator is reduced through the relay switch when the motor is started, the starting efficiency of the motor stator is improved.

[0023] The relay switch can use the following method to make the motor stator reduce the resistance of the multiple coils when starting, for example, control one or more of the multiple coils to short circuit when the ...

Abstract

The invention discloses a motor stator, a motor and a control method thereof. The motor stator comprises a plurality of coils and a relay switch, wherein one or more coils are connected, so the resistance of the coils is reduced when the motor starts up. According to the invention, the problem that the start-up efficiency of the motor stator is lower in related technologies can be solved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor stator, a motor and a control method thereof. Background technique [0002] Since there is a permanent magnet in the rotor of the self-starting motor, the permanent magnet generates a braking torque when starting, which makes it very difficult to start the motor. In the related technology, the start-up capability is generally increased by increasing the capacitance, adjusting the number of primary and secondary phase turns, reducing broken rings, etc., but the efficiency will decrease accordingly. [0003] The structure diagram of single-phase self-starting permanent magnet synchronous motor is as follows figure 1 Shown, and single-phase asynchronous motor (such as figure 2 Shown) compared to the presence of permanent magnets in the rotor, the starting ability of the motor is reduced. As shown, the motor includes a primary phase winding 10 , an auxiliary phase winding 20 and a p...
