Single-layer Windings can only descend whole distance in theory, can not descend short distance because Single-layer Windings makes short distance, often extremely under groove number cannot mean allocation, and bilayer always can mean allocation.With 18 groove motors for example, Fig. 4 is the winding distribution map of individual layer short distance winding that the utility model adopts, and as can be seen from Figure 4, the A phase of Single-layer Windings, B phase and C Entropy density deviation are also uneven.Fig. 5 is in double-deck short distance winding distribution map, and three-phase windings distribution is completely the same.
Contrast by experiment, with wire diameter double-deck short distance coiling 550 circle of Φ 0.08, electric current is 0.08A, staor winding welds a thermistor PT100, is energized 1.5 hours, temperature rise is 76 DEG C, make individual layer short distance laxative remedy into, winding 1300 circle, electric current 0.057A, same energising 1.5 hours, temperature rise is only 27 DEG C.Staor winding is wrapped on stator iron core according to the laxative remedy of individual layer short distance, greatly improves the heat dissipation environment of motor, reduces electric current, improves product efficiency.
The interchange drum type axial-flow blower of described individual layer short distance belongs to threephase asynchronous, during blower fan work, pass into three-phase 380V, 50Hz symmetrical current, rotating magnetic field is set up in air gap, this rotating magnetic field produces induction electromotive force and produce corresponding electric current in casting aluminum rotor sliver in the casting aluminum rotor sliver of short circuit, rotating magnetic field in this electric current and air gap interacts and produces electromagnetic torque, rotor rotates under the influence of this torque, rotor drives flabellum to rotate and produces air flowing, realize blower fan function.For certain device power supply (DPS) cabinet ventilation and heat, also can be used for the uses such as the large ground automatic controller of air requirement and ventilation, heat radiation, purification.
The interchange drum type axial-flow blower air quantity of described individual layer short distance is large, it is little to vibrate, noise is low, and structure is simple, is convenient to install, exchange and maintenance, wide market.
