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 5500-watt 4-pole three-phase asynchronous motor. The difference is that the stator outer diameter 11 of the stator core is made into 21.00cm, the stator inner diameter 12 is made into 13.70cm, and the length of the stator core is made into 20.00cm. The number of stator punching slots 3 on the stator punching sheet 1 is made into 36 and distributed evenly in a ring shape, and the slot shape is made into a round top and round bottom slot, in which the slot width 31 is made 2.50mm, and the slot height 32 is made into 0.80mm, deep groove top 33 is made into 14.20mm, groove top radius 34 is made into 3.50mm, groove bottom radius 35 is made into 4.20mm.

[0029]At the same time, the rotor outer diameter 21 of the rotor iron core is made 13.62 cm, the rotor inner diameter 22 is made 4.20 cm...

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 relates to a super ultrahigh efficient 5,500W four-grade energy-saving environmental-friendly electric motor which is characterized in that the inner and outer diameters and length sizes of stator and rotor cores, groove shapes and sizes of a stator and a rotor and a number of grooves are subjected to integral coordination design, so that loss of the stator, the rotor and the cores is greatly reduced; then punching holes are additionally formed in stator and rotor punches to form core hole passages, so that heat temperature convection in the motor is increased and temperature rise is reduced and retarded; specially-made rotor cast aluminium is adopted so as to effectively improve electric conductivity and a heat dissipation effect; a stator winding is tapped at the one second position of a coil so as to greatly reduce loss of a harmonic component, thereby further reducing iron loss and copper loss. A comprehensive effect of various schemes greatly reduces electric energy loss, so that on the premise of stabilizing an output power of the product into 5.5 kW, the input power of the product is only 5.962kW and energy conversion efficiency of the product reaches 92.3 percent, exceeds the national YE 4-grade energy efficiency standard which is the highest grade energy efficiency standard, also exceeds the international IE 4-grade standard which is the highest grade standard and 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 5500-watt 4-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...
