Problems solved by technology

[0002] The stator of the washing machine motor produced at present is composed of several punched sheets. However, the structure of the existing stator punched sheets is not ideal, which makes the magnetic density of the stator teeth and the front part high, which leads to low motor efficiency and high electromagnetic noise.
With the implementation of the new energy efficiency standards for washing machines, in order to make the existing washing machine motors meet the new energy efficiency standards, the existing ordinary motors need to increase the thickness of the iron core and increase the amount of copper used in the winding, which leads to an increase in the size of the motor. The use of raw materials such as iron and copper has been greatly increased, which greatly increases the production cost of the motor

Abstract

The invention discloses an efficient motor stator for a washing machine. The size phi of a round side M (6) is 120-130mm, the size of a tangent side (7) is 115-125mm, and the size phi of a hollow inner circular hole (2) is 70-75mm. The size phi of a circle of the top of a shallow groove I (4) of a punching plate groove (3) is 99-103mm, and the size phi of a circle of the top of a deep groove II (5) of the punching plate groove (3) is 101-105mm. The efficient motor stator for the washing machine is reasonable in structure and size, motor efficiency is effectively improved, usage of raw materials of a motor is reduced, motor cost is reduced, and accordingly product competitiveness is improved.
