This structure is mounted on the stator of the motor, with stator slots numbered 1-24 arranged counter-clockwise.

[0019] In this context, the number represents the stator slot numbered by that number, and the symbol "-" indicates that the winding group connects the stator slot numbered by the number before the symbol "-" to the stator slot numbered by the number after the symbol "-".

[0020] The main winding coil and the secondary winding coil are connected in parallel, and a capacitor is connected to the secondary winding coil.
