Problems solved by technology

At present, the Y2 series 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. The center height is 132-2 pole motors, the above defects are more prominent

Embodiment Construction

[0011] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0012] The present invention only needs to change the punching die of the stator punching sheet, and punches out the stator punching body 1 on the punching machine with a 50WW470 cold-rolled silicon steel sheet, and 36 grooves 2 are arranged on the stator punching body 1 . The proposal of the present invention does not change the original assembly mode of the motor.

[0013] In the stator punching groove type, the stator punching slot width bs1 is 6.2 mm; the stator slot width b01 is 3.2 mm; the stator slot bottom radius bs2 is 8.2 mm; the stator slot shoulder slope angle zs1 is 30 degrees; The height hs0 is 0.8mm; the total height hs12 of the stator slot is 18.5mm.

Abstract

The invention relates to a stator punching of a motor, which comprises a stator punching body, wherein 36 stator punching slots are arranged in the stator punching body. In the stator punching slots, the slot width bs1 is 6.2mm; b01 is 3.2mm; bs2 is 8.2mm; zs1 is 30 degrees; hs0 is 0.8mm; and hs12 is 18.5mm. The invention only needs to change the punching die of the stator punching without changing the original assembling mode of the motor. The punching is used in a stator core with center height of 132 and two poles of a high-efficiency motor, can improve the efficiency of the motor, and can ensure small electromagnetic noise, low starting current and large torque in the long-term service process.

Description

technical field [0001] The invention relates to a stator punching sheet of a motor, in particular to a stator iron core for a high-efficiency motor whose central height is 132-2 poles. Background technique [0002] In today's society where global resources are scarce, people's awareness of energy conservation and emission reduction and low-carbon life is increasing day by day. The country is also vigorously promoting energy conservation and emission reduction, and improving the energy efficiency of electric motors is one of the ways to achieve this goal. At present, the electric motors widely used in the fields of industry, agriculture, commerce, construction and transportation, generally have defects such as low efficiency and high energy consumption, and cannot meet the requirements of high efficiency, energy saving and emission reduction. [0003] Stator punching is a key component in the motor, and its material, inner circle size, outer circle size, slot shape size, how...
