Motor stator for efficient smoke ventilator

Abstract

The invention discloses a motor stator for an efficient smoke ventilator. The motor stator for an efficient smoke ventilator comprises a plurality of punching sheets, wherein the punching sheets are laminated in order to form a stator; the first 2-5 punching sheets of the stator are bonded together; the latter 2-5 punching sheets of the stator are bonded together; a hollow inner round hole is formed in the center of each punching sheet; a plurality of punching sheet slots are arranged in the radial direction of the hollow inner round hole; each punching sheet slot includes 16 deep slots and 8 shallow slots; the 8 shallow slots are divided into four groups of shallow slots on average; one group of shallow slots is arranged between the two adjacent groups of deep slots; the four groups of deep slots and the four groups of shallow slots are distributed in uniform intervals; and the width of one punching sheet tooth formed between the deep slot and the adjacent shallow slot is 4.5-4.8mm. The motor stator for an efficient smoke ventilator has the advantages of being reasonable in structure, greatly reducing the electromagnetic noise, effectively improving the motor efficiency, reducing the application amount of the raw materials of the motor, reducing the cost of the motor, and improving the market competitiveness of products.

Description

【Technical field】 [0001] The invention relates to a motor stator for a high-efficiency range hood, in particular to a stator punching sheet for a range hood with two types of grooves, which belongs to the field of motor processing and manufacturing. 【Background technique】 [0002] The stator of the motor used for range hoods currently produced 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 yoke part high, resulting in low motor efficiency and electromagnetic interference. The noise is high. With the implementation of the new energy efficiency standard, in order to make the existing motor meet the new energy efficiency standard, the current motor needs to increase the thickness of the iron core and increase the amount of copper used, which leads to an increase in the size of the motor and the use of a single motor. The use of raw materials such as ir...

[0002] The stator of the motor used for range hoods currently produced 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 yoke part high, resulting in low motor efficiency and electromagnetic interference. The noise is high. With the implementation of the new energy efficiency standard, in order to make the existing motor meet the new energy efficiency standard, the current motor needs to increase the thickness of the iron core and increase the amount of copper used, which leads to an increase in the size of the motor and the use of a single motor. The use of raw materials such as iron and copper has increased significantly, which greatly increases the manufacturing cost of the motor
