Embodiment 1

[0028] As shown in the figure, the present invention includes two core parts, the stator and the rotor. The basic material, structure and manufacturing method are the same as those of the ordinary 2200-watt 6-pole three-phase asynchronous motor. The difference is that the stator outer diameter 11 of the stator core is made into 17.50cm, the stator inner diameter 12 is made into 12.10cm, and the length of the stator core is made into 15.50cm. The number of stator punching slots 3 on the stator punching sheet 1 is made into 36 and evenly distributed in a ring shape, and the groove shape is made into a groove with a sloping shoulder and a round bottom, in which the slot width 31 is made 2.80mm, and the slot height 32 is made into 0.80mm, the groove top depth 33 is made into 11.40mm, the groove shoulder width 34 is made into 5.54mm, the groove shoulder height 35 is made into 0.83mm, and the groove bottom radius 36 is made into 3.81mm.

[0029]At the same time, the rotor outer diam...

Embodiment 2

[0031] Further, on the basis of Embodiment 1, a double-layer ring-shaped stator punching hole band 5 is arranged on the periphery of the bottom of the stator punching groove 3 above the stator punching plate 1, and the inner layer of the stator punching hole band The inner ring line of ring 5 coincides with the circumscribed circumferential line 51 at the bottom of the stator punching slot. 36 evenly distributed stator punching holes 52 are arranged on the sheet hole belt ring 5, and the shape of the stator punching hole 52 is set as an equilateral triangle with a side length of 2.30mm, wherein the inner stator punching hole belt ring The stator punching hole 52 is located at the midpoint of the arc-shaped band between two adjacent stator punching slots, and the stator punching hole 52 on the outer stator punching hole ring is located at the inner layer stator punching hole ring. The midpoint of the arc band between the two holes of the stator punching hole 52 .

[0032] At t...

Embodiment 3

[0035] Further, the rotor punching holes 62 on the first rotor punching sheet 2 in the embodiment 2 are evenly distributed on any point of the outer rotor punching hole ring and the inner rotor punching hole ring, Then the rotor punching hole 62 on the adjacent rotor punching 2 rotates in the same direction (clockwise or counterclockwise) on the rotor punching hole ring 6 sequentially, and the displacement is 0.05mm or 0.1mm or 0.25mm or 0.35mm or a displacement of 0.5mm, when the rotor punches 2 are sequentially stacked, a spiral hole will be formed on the rotor core as a whole. When such a motor is running, it will further accelerate the heat temperature convection in the motor, and make the air flow more fully, further reduce and slow down the temperature rise, and reduce the rotor loss.

Abstract

The invention discloses a super ultra efficient 2.2 kW energy-saving and environment-friendly motor with six poles. The motor is characterized in that the inner and outer diameters and lengths of stator and rotor iron cores, and the shapes, sizes and number of slots in a stator and a rotor are designed in a coordinated mode on the whole, and losses of the stator, the rotor and the iron cores are greatly reduced; punching holes are additionally formed in stator and rotor sheets to form iron core hole channels, heat and temperature convection inside the motor is increased, and temperature rise is reduced and relieved; specially-made rotor cast aluminum is adopted for effectively improving the electric conductivity and the radiating effect; tapping is carried out on the middle of a coil of a stator winding, harmonic component losses are greatly reduced, and then iron losses and copper losses are reduced. According to the synthesizing effect of various schemes, electric energy losses are greatly reduced, the input power of the motor only needs 2.516 kW on the premise that the output power of the motor is stabilized to be 2.2 kW, energy conversion efficiency reaches 87.5% which exceeds the national highest level YE4-grade energy efficiency standard and also exceeds the international highest level IE4-grade standard, and the motor reaches the international advanced level.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to an ultra-super-high-efficiency 2200-watt 6-pole energy-saving and environment-friendly electric motor exceeding the international IE4 energy efficiency standard. Background technique [0002] Electric energy is an important material energy that people rely on for survival, and its application has penetrated into various fields of society. Today's people's life and work are inseparable from electric energy. However, due to the excessive use of electric energy, it has brought huge negative effects to the natural environment in which people live, and the environmental damage is very serious. In order to improve the environment, energy conservation and emission reduction have become an unavoidable topic in the world today. In the field of electricity, because the electricity consumption of the motor system accounts for about 60% of the total electricity consumption in my coun...
