Example Embodiment
[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0037] The invention discloses a permanent magnet synchronous motor structure with high power density, which includes a stator assembly 1 and a rotor 2. The stator assembly 1 includes a stator core 11, an insulating frame 18, a stator winding 15 wound on the stator core and the insulating frame, a stator bush 12, an end collector ring 14, and an end insulating plate 13 made of insulating material. An enameled wire is wound on the stator core 11 to form a stator coil. The coils on two adjacent teeth form a set of stator windings 15, and two taps are drawn from both ends of each set of windings.
[0038] Such as Figure 7 The illustrated stator bushing 12 has an axial bore p...
