Embodiment
As shown in Figure 3, the utility model comprises main winding X, Y, Z, auxiliary winding X ', Y ', Z ' and operation capacitor C, described auxiliary winding X ', Y ', Z ' are after capacitor C connects with each operation respectively, again respectively with corresponding main winding X, Y, Z parallel connection, last common the access on the power frequency three phase mains, wherein said auxiliary winding lags behind 30 ° of mechanical angles of main winding, operation electric capacity described and auxiliary windings in series will be assisted 90 ° of winding phase shifts, make and form 60 ° of phase angles between all windings, form circular magnetic field as much as possible, the inductiopn rotor steady running.
Its three-phase output voltage waveform is compared with Fig. 2 as shown in Figure 4, and the voltage that oblique line is partly exported further produces magnetic field, make the current on time of motor higher, magnetic field is more even, and moment is stable, and impulse current is little, and it is simple in structure, cost is low, the reliability height, and efficient is especially high, can reach 90%, obviously than existing Y, Y2 series threephase motor height.
Described operation electric capacity is according to existing computational methods or utilize oscilloscope to select operation capacitance rationally, (choosing of electric capacity of operation can be adopted the prior art means, here do not give unnecessary details) make that the phase angle between the output voltage is more accurate, more approaching circular magnetic field, the magnetic field of generation.
More than stator winding structure of asynchronous motor provided by the utility model is described in detail, used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
