Abstract

A main and assistant winding of single-phase motor stator belongs to the design and manufacturing technology of motor. The winding comprises a main winding and an assistant winding which are embedded in the trunking of the motor stator. Though deflecting the assistant winding by 15 degree, the electric potential included angle between the main and assistant winding can be 75 degree. The winding can increase the starting torque of the motor and improve efficiency. When the starting torque is the same, the lower power motor can be selected. Thereby, the enameled wire material and so on can be saved and the cost is reduced. The winding can be widely used in all kinds of single-phase motors using capacitance to start.

Description

The major-minor winding of single-phase motor stator

Technical field

The utility model belongs to the motor technology field, more particularly relates to the improvement of space angle of major-minor winding of the monopole asynchronous motor stator of capacitor start.

Background technology

The space angle of the major-minor winding of traditional capacitor start monopole asynchronous motor stator is 90 degree.That is to say that the current potential angle of the rule of its major-minor winding that is its space angle are 90 degree.

The starting torque of this rule mode motor is less, and efficient is lower.When the same starting torque of needs, must select more powerful motor.Thereby economical inadequately, and need consume materials such as more enamelled wire.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of major-minor winding of single-phase motor stator of capacitor start is provided.Angle of its auxiliary winding skew increases the starting torque of motor, and efficient improves.When same starting torque, can select lower-powered motor.Thereby save material such as enamelled wire, reduced cost.

In order to achieve the above object, the utility model comprises main winding and the auxiliary winding in the wire casing of the stator that is inlaid in motor.Its auxiliary winding skew 15 degree, the current potential angle angle that makes the major-minor winding is 75 degree.

The electric capacity of the single-phase motor of capacitor start and the effect of auxiliary winding are: give the auxiliary winding phase shift, starting torque is increased, finish the starting task.Auxiliary winding skew 15 degree of the present utility model, the current potential angle angle that makes the major-minor winding is 75 degree.Thereby can reach the starting torque of increasing motor, the purpose of saving the winding enamelled wire.

Task of the present utility model comes to this and finishes.

Auxiliary winding skew 15 degree of the present utility model increase the starting torque of motor, and efficient improves.When same starting torque, can select lower-powered motor.Thereby save material such as enamelled wire, reduced cost.Can be widely used in the single-phase motor of various capacitor starts.
