Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In Fig. 1 ~ 8, comprise stator core 1, taper surface 1-1, yoke 1-2, stator winding 2, magnet steel 3, rotor 4, bearing 5, rotating shaft 6, end cap 7, casing 8, boss 8-1 etc.
As shown in Fig. 1 ~ 8, the utility model is a kind of tapered air gap axial double loop magnetic field permanent magnet synchronous machine, the stator core 1 comprising casing 8 and be arranged in casing 8 and rotor 4, coil windings has two groups, often organize coil windings to be made up of N number of small coil, and described two groups of coil windings share a described stator core 1; The two ends of stator core 1 all form taper surface 1-1, and each described taper surface 1-1 is all equipped with a rotor 4, and the magnet steel 3 that interlaced arrangement polarity is different on taper surface 1-1; To form tapered air gap in casing, described casing 8 inwall centre position forms boss 8-1, and described stator core 1 is all arranged with stator winding 2, and two groups of stator winding 2 all independently separate, and is formed two " sub-motor ".During operation: can use a set of, another set ofly to generate electricity; Also can two cover and use, the instructions for use of different client can be met preferably, effectively can improve service efficiency.The distance that described stator core 1 is all arranged with between two groups of stator winding, 2, two stator winding can adjust; Boss 8-1 width dimensions in the middle of casing 8 inwall also changes along with the distance change between winding.
Stator core 1 outward appearance is cylindric, and stator core 1 comprises some yokes be uniformly distributed along the circumference, and yoke cross section is fan-shaped, and vertical section is trapezoidal; Taper surface 1-1 is inner conical surface or male cone (strobilus masculinus).Casing 8 two ends connect an end cap 7 respectively, and rotating shaft 6 is by bearing 5 rotating support on end cap 7, and rotor 4 is driven by rotating shaft 6 and rotates.
