Ultrahigh energy efficiency 750W two-pole three-phase asynchronous motor

Abstract

Provided is an ultrahigh energy efficiency 750W two-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 216.2W to 155.2W, and reduction is 28.2% under the premise of the same output power of 750W. The required input power is reduced from original 0.966kW to 0.905kW, energy conversion efficiency is increased from 77.6% to 82.9%, and increment is 5.3%. Compared with standard of 80.7% which is specified in the latest national standard "GB18613-2012" and enforced in September, 2016, energy conversion efficiency surpasses for 2.2% so that energy conversion efficiency is substantially enhanced. Application and popularization of the ultrahigh energy efficiency 750W two-pole three-phase asynchronous motor provide powerful support for national energy conservation and emission reduction work.
