Abstract
Description
Technical Field
[0001] The utility model relates to a capacitor motor, in particular to a stator core of a capacitor motor. Background Art
[0002] The capacitor motor generally includes a housing, a rotor, a stator and a starting capacitor. The stator is provided with a stator core, a starting winding coil and a running winding coil. The starting winding coil and the running winding coil are wound in the wire slots of the stator core. When working, the characteristics of the capacitor are used to generate a phase between the starting winding coil and the running winding coil, so that the stator generates a rotating magnetic field, and then the rotating magnetic field is used to drive the rotor to rotate. However, the wire slots opened on the stator core of the existing capacitor motor are of the same size, that is, the wire slots corresponding to the starting winding coil are the same size as the wire slots corresponding to the running winding coil; therefore, the cross-section of the wire slots of the running winding coil cannot be increased on the stator core, resulting in a smaller wire diameter of the running winding coil, which makes the capacitor motor generate a lot of heat and the output torque and power cannot be improved.
[0003] Based on the above-mentioned deficiencies, a better capacitor motor is now needed. Utility Model Content
[0004] The utility model aims to provide a stator core of a capacitor motor which can reduce the heat generation of the capacitor motor and improve the output torque and power.
[0005] Another object of the present invention is to provide a capacitor motor that can reduce heat generation and increase output torque and power.
[0006] In order to achieve the above-mentioned purpose, the capacitor motor stator core provided by the utility model includes a core body, in which a first wire groove is relatively arranged on both sides of the core body and a second wire groove is relatively arranged on both sides of the core body, the first wire groove and the second wire groove are arranged at a certain angle around the central axis of the core body, and the cross-sectional area of the first wire groove is greater than the cross-sectional area of the second wire groove.
[0007] The number of the first wire slots is greater than the number of the second wire slots.
[0008] Compared with the prior art, the utility model reduces the cross-sectional area of the second wire slot, thereby leaving a certain space in the stator core to increase the cross-sectional area of the first wire slot, so that the cross-sectional area of the first wire slot is larger than the cross-sectional area of the second wire slot. Therefore, the resistance can be reduced by increasing the wire diameter of the running winding coil, thereby greatly reducing the heat generation of the running winding coil during operation, and at the same time can increase the output torque and improve the power of the motor.
[0009] A capacitor motor includes a housing, a rotor, a stator and a starting capacitor, wherein the stator is arranged in the housing, the rotor is rotatably sleeved in the stator, the stator includes a running winding coil, a starting winding coil and a stator core, the stator core includes a core body, the core body is provided with a first wire slot relatively arranged on both sides of the core body and a second wire slot relatively arranged on both sides of the core body, the first wire slot and the second wire slot are arranged at a certain angle around the central axis of the core body, and the cross-sectional area of the first wire slot is greater than the cross-sectional area of the second wire slot. The running winding coil is wound in the first wire slot, the starting winding coil is wound in the second wire slot, and the starting capacitor is connected in series with the starting winding coil and then connected in parallel with the running winding coil.
[0010] Preferably, the number of the first wire slots is greater than the number of the second wire slots. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a circuit diagram of the capacitor motor of the utility model. DETAILED DESCRIPTION
[0013] In order to explain the technical content, structural features and effects achieved by the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.
[0014] like Figure 1 and Figure 2 As shown, a capacitor motor 100 of the utility model includes a housing (not shown), a rotor 1, a stator 2 and a starting capacitor 3, wherein the stator 2 is arranged in the housing, the rotor 1 is rotatably sleeved in the stator 2, and the stator 2 includes a running winding coil 21, a starting winding coil 22 and a stator core 23. The stator core 23 includes a core body 231, wherein the core body 231 is provided with first wire slots 232 and second wire slots 233 arranged on both sides of the core body 231, the first wire slots 232 and the second wire slots 233 are arranged at a certain angle around the central axis of the core body 231, and the cross-sectional area of the first wire slots 232 is greater than the cross-sectional area of the second wire slots 233. The number of the first wire slots 232 is greater than the number of the second wire slots 233. The running winding coil 21 is wound in the first wire slot 232 , the starting winding coil 22 is wound in the second wire slot 233 , and the starting capacitor 3 is connected in series with the starting winding coil 21 and then connected in parallel with the running winding coil 22 .
[0015] The utility model reduces the cross-sectional area of the second wire slot 233, thereby leaving a certain space in the stator core 23 to increase the cross-sectional area of the first wire slot 232, so that the cross-sectional area of the first wire slot 232 is larger than the cross-sectional area of the second wire slot 233. Therefore, the resistance can be reduced by increasing the wire diameter of the running winding coil 21, so that the heat generation of the running winding coil 21 is greatly reduced during operation, and at the same time, the output torque can be increased, thereby improving the power of the motor.
[0016] The rotor 1 structure and the winding structure of the winding coil involved in the capacitor motor of the present invention are well known to ordinary technicians in the field and will not be described in detail here.
[0017] The above disclosure is only a preferred example of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
