Embodiment Construction

[0017] The present invention will be further described below in conjunction with embodiment.

[0018]As shown in the figure, the present invention includes two core parts, a stator and a rotor. The basic material, structure and manufacturing method are the same as those of a common 1500-watt 6-pole three-phase asynchronous motor. The difference is that the stator outer diameter 11 of the stator core 3 is made 16.0cm, the inner diameter of the stator 12 is made 9.9cm, and the length of the stator core 3 is made 12.0cm; the stator punch heat sink 5 is added to the stator punch 1, and the stator punch groove 6 and the stator buckle groove 4 combined to form a stamping structure; the number of stator stamping slots 6 is made into 24 and evenly distributed in a ring shape, and the slot shape is made into a round-bottomed slot with inclined shoulders, and the slot width 61 is made into 2.00mm , the slot height 62 is made into 0.50mm, the depth of the upper part of the slot is 63 to ...

Abstract

Provided is an ultrahigh-efficiency and energy-saving 1500W six-pole three-phase asynchronous motor which comprises a stator and a rotor. Design of external diameters, internal diameters, length of iron cores, number of punching sheet grooves and shape and size of the grooves of the stator and the rotor is systematically optimized so that stator winding loss, rotor winding loss and iron core loss are substantially reduced. Compared with existing similar products, total energy loss amount is reduced from 515.9W to 292.7W, and reduction is 43.3% under the premise of the same output power of 1500W. The required input power is reduced from original 2.016kW to 1.793kW, energy conversion efficiency is increased from 74.4% to 83.7%. Compared with 1500W six-pole three-phase asynchronous motor efficiency standard requirement of 82.5% which is specified in the highest grade of IE3 of international motor energy efficiency grade standard, energy conversion efficiency is enhanced for 1.2% so that energy conversion efficiency is substantially enhanced.

Description

technical field [0001] The invention relates to a motor, in particular to a super-high-efficiency and energy-saving 1500-watt 6-pole three-phase asynchronous motor.
