Abstract
The invention discloses a method for designing stator windings of an asynchronous starting three-phase permanent magnet synchronous motor. The stator windings adopt a crossed winding mode, five varnished wires are wound on each phase of stator windings in a duplex mode, each coil has 46 turns, each phase of stator windings has one parallel branch, the varnished wires include three varnished wires with 0.63mm diameters and two varnished wires with 0.8mm diameters, the thickness of each varnished wire with the 0.63mm diameter is 0.037mm, and the thickness of each varnished wire with the 0.8mm diameter is 0.028mm. By means of the asynchronous starting three-phase permanent magnet synchronous motor manufactured by the method, copper loss of the stator windings is reduced effectively, work efficiency of the stator windings reaches 93.6 percent, efficiency is always higher than 92 percent within 30 percent-140 percent of rated load, and a power factor reaches 0.97. Therefore, the asynchronous starting three-phase permanent magnet synchronous motor can replace an ordinary asynchronous motor in the existing industrial field, and purposes of high efficiency and energy saving are achieved.
Description
Technical field
The present invention relates to three-phase permanent-magnetic synchronous motors stator winding, especially relate to asynchronous starting three-phase permanent-magnetic synchronous motors stator winding design method.
Background technology
Motor is the widely used electric equipment of national economy every profession and trade, and use amount is large, long operational time, and therefore, the power consumption while reducing motor work is an energy-conservation effective way.Compare with common threephase asynchronous, asynchronous starting three-phase permanent-magnetic synchronous motors has high efficiency, High Power Factor and the wide advantages such as economical operation scope, has significant energy-saving effect.
Summary of the invention
The object of the invention is just to provide a kind of asynchronous starting three-phase permanent-magnetic synchronous motors stator winding design method with High Power Factor.
For achieving the above object, the present invention takes subordinate's technical scheme:
Asynchronous starting three-phase permanent-magnetic synchronous motors stator winding design method of the present invention, described stator winding adopts staggered form winding mode; Every phase stator winding be 5 around enamelled wire radical, coil turn is 46, parallel branch number is 1, adopt 3 0.63mm diameters and 2 0.8mm diameters enamelled wire and around; The magnet wire insulation thickness of described 0.63mm diameter is 0.037mm; The magnet wire insulation thickness of described 0.8mm diameter is 0.028mm.
The asynchronous starting three-phase permanent-magnetic synchronous motors of manufacturing according to the inventive method, due to every phase stator winding and be set to 5 around enamelled wire radical, coil turn is set to 46, parallel branch number is set to 1, and adopt 3 0.63mm diameters and 2 0.8mm diameters enamelled wire and around, therefore effectively reduce the copper loss of stator winding, its operating efficiency reaches as high as 93.6%, and in 30%～140% nominal load internal efficiency all up to more than 92%, power factor reaches 0.97, substitutes existing industrial circle and reaches energy-efficient object by normal asynchronous.
