Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0011] The present invention only needs to change the stamping die of the stator punching sheet, and punch out the stator punching body 1 on the punching machine with a 50WW470 cold-rolled silicon steel sheet. 1 There are 72 stator punching slots evenly arranged on the inner circumference 2, such as figure 1 shown. The proposal of the present invention does not change the original assembly mode of the motor.

[0012] Such as figure 2 As shown, in the slot shape of the stator punching sheet: the stator slot width bs1 and the stator slot height hs1 can be increased or decreased according to the actual needs of the power, the stator notch height h0=1mm, the stator slot height h1=4.5mm, the stator slot height h1=4.5mm, The slope angle of the groove shoulder zs1=45 degrees.

Abstract

The invention relates to a circular ring-shaped stator punching sheet. The stator punching sheet comprises a stator punching sheet body; 72 stator punching sheet grooves are uniformly arranged at a circumference in the stator punching sheet body; in each the punching sheet groove, h0 is 1 millimeter; h1 is 4.5 millimeters; and zs 1 is 45 degrees. According to the invention, a stamping die of a stator punching sheet is changed without changing of an original assembling mode of a motor; the punching sheet is applied in a stator iron core of a YKK 500-8 high pressure and high efficient motor with a voltage of 10, 000 V and an efficiency of the motor can be improved; moreover, after the stator punching sheet is utilized for a long time, electromagnetic noise is low, a starting current is small and a torque is large.

Description

technical field [0001] The invention relates to a ring-shaped stator stamping sheet for a high-voltage high-efficiency motor, in particular to a stator core for a YKK500-8 10000V pole of a high-voltage high-efficiency motor. Background technique [0002] For the YKK500-8 high-voltage motor, due to the incomplete consideration of the original traditional design, non-standardization, poor supporting parts, and inconvenient use and operation, problems often occur. [0003] Stator punching is a key component in the motor, and its material, inner circle size, outer circle size, slot shape size, how many, etc. have a direct impact on the efficiency of the motor. At present, the Y series high-voltage motors that are most used in the market can no longer achieve the purpose of improving the efficiency of the stator, and in the long-term use process, it is found that it still has defects such as large electromagnetic noise, large starting current, and small torque.
