Further, as depicted in figs. 1 and 2, the maximum radial dimension of stator yoke 11 is D, the maximum of rotor core 20
Radial dimension is d.For etc. shapes stator core 10, i.e. the timing of maximum radial dimension D mono- of stator yoke 11, when d/D mistakes
Hour, the maximum radial dimension d of rotor core 20 is too small, if 100 low speed of motor is run, for example, the rotating speed ＜ of motor 100
The load capacity of 5000rpm, rotor core 20 are too small, drive under the operating mode loaded on an equal basis, rotor too small maximum radial dimension d
Iron core 20 can seriously generate heat, and influence the normal operation of motor 100, reduce by 100 efficiency of motor, in some instances it may even be possible to be damaged.
When d/D is excessive, the cogging torque of motor 100 can be caused to become larger, the rotary inertia of rotor core 20 becomes larger, if
100 high-speed cruising of motor, for example, when the rotating speed ＞ 10000rpm of motor 100, motor 100 will produce vibration, and then generate larger
Noise, influence the use feeling of motor 100 performance and user.

Coil not only improves the weight for mitigating motor 100, reduces the volume of motor 100, and is not necessarily to start excitation on startup, opens
It is dynamic more quick, it is more energy saving.
It should be noted that the utility model the quantity of magnet slot 23 and permanent magnet 25 is not done it is specifically limited, it is only necessary to
Meet multiple permanent magnets 25 to be plugged in correspondingly in multiple magnet slots 23 to realize the fixation of permanent magnet 25 and be formed multiple
The requirement of magnetic pole.For example, in specific embodiment as shown in Figures 2 and 3, magnet slot 23 and permanent magnet 25 are respectively four
A, four permanent magnets 25 are plugged in respectively in four magnet slots 23.For another example in other embodiments of the utility model,
Magnet slot 23 and permanent magnet 25 can also be respectively two, six, eight or more, this is all in the protection of the utility model
Within the scope of.
In addition, each at least one end of magnet slot 23 in the circumferential direction of rotor core 20 can be equipped with locating slot 24, permanent magnetism
Locating slot 24 can be inserted while being inserted into magnet slot 23 in body 25, and locating slot 24 can further limit the position of permanent magnet 25
It sets, so that 25 position of permanent magnet is fixed more accurate secured.
Further, as shown in Figures 2 and 3, the straight line at both ends of each magnet slot 23 in the circumferential direction of rotor core 20
Distance is b, and the maximum radial distance of the peripheral surface of the centre distance rotor core 20 of rotor core 20 is R, and b and R meets
b:R=0.95-1.0.
Work as b:When R ＜ 0.95, the length of permanent magnet 25 is too short in magnet slot 23, reduces the utilization rate of rotor core 20, from
And reduce the efficiency of motor 100；Work as b:When R ＞ 1, the leakage field of rotor core 20 is will increase, can also reduce the energy of motor 100
Effect.Therefore, in some embodiments of the utility model, b:When R=0.95-1.0, for example, in some tools of the utility model
