Description
Technical field
The present invention relates to the permanent magnetic brushless that electro-tricycle uses, be specifically related to the rotor magnetic steel of a kind of 12 groove 10 poles
Built-in permanent magnetic brushless motor.
Background technology
The magneto that existing market electro-tricycle uses, mostly is 12 groove 8 electrode structure forms, and its rotor is that surface embeds
Form, rotor magnetic steel non-working side leakage field is serious, and internal rotor has the more magnetic line of force to be distributed, additionally due to magnet steel is exposed to gas
In breath field, the most easily demagnetize, During Process of Long-term Operation reduces electrical machinery life, and easily causes magnet steel breakage harm, limit
High-speed cruising ability processed；This version weak magnetic scarce capacity, has influence on the output-constant operation scope of motor.
Summary of the invention
Goal of the invention: for the deficiency of the brushless electric machine existence of above-mentioned 12 groove 8 polar forms, propose turning of a kind of 12 groove 10 poles
Sub-built-in permanent magnetic brushless motor, the groove number that stator uses is 12 grooves, and rotor uses the form of 10 poles, and rotor magnetic steel uses V-type
Embedded, protect magnet steel face, improve it and resist degaussing ability, increase motor stabilizing service life and promote its high speed performance, effectively
The weak magnetic energy power of lifting motor, expands the output-constant operation scope of motor.
Technical scheme: a kind of 12 groove 10 pole permanent magnet brushless motors, including stator and rotor, the groove number of described stator is 12
Groove, described rotor uses the form of 10 poles, described rotor to be provided with 20 slot wedges, installs 20 magnetic links between slot wedge, and magnetic links is adopted
Embedded by V-type, each V-type unit is made up of two adjacent magnetic links, and 10 V-type unit are evenly distributed on peritrochanteric, magnetic
Steel disc is positioned at that two face polarity of V-type mouth are identical and V-type opening is towards the surface of rotor, the pole of each V-type unit opening part
Property the polarity of two V-type unit opening parts that is adjacent different, described magnetic links thickness is 3.0 ± 0.01mm.
Further, slot wedge end is provided with magnet isolation tank.
Further, magnetic links is embedded in the stalloy of superposition, and the thickness of stalloy is 0.35 ± 0.01mm.
Beneficial effect:
(1) magneto typically has saliency, and this effect can produce reluctance torque, the weak magnetic energy power of lifting motor,
Directly affect the output-constant operation scope of motor.Saliency is decided by that permanent magnet machine rotor exists theoretic inductance, respectively
The q axle inductance produced for rotor core material, with permanent magnet produce d axle inductance, surface embedded type rotor d axle and q axle electricity
Feeling equal, rotor does not have saliency, does not produce reluctance torque, so its weak magnetic property is more weak；But 12 groove 10 pole magnet steel
Embedded permanent magnetic motor, q axle inductance is more than d axle inductance, and rotor has saliency, thus has reluctance torque, effectively promotes
Motor weak magnetic property, because of the improvement in output-constant operation stage, is effectively improved the power density of motor.Actual test 48V600W shape
The motor rotor magnetic steel built-in permanent magnetic motor of formula, promotes with magnet steel surface embedded type magneto output-constant operation scope relatively
About 15%.
(2) rotor of surface embedded type, magnet steel is directly exposed to breath magnetic field axis, can going for a long time by stator field
Magnetic, causes in motor During Process of Long-term Operation and demagnetizes, and shortens the time that motor stabilizing runs；Magnet steel is exposed in breath exist magnet steel
Damaged major hidden danger, its high-speed cruising ability directly limited；The magnet steel surface embedded type rotor inoperative magnetic that leaks hunting is serious, non-
More magnetic line of force distribution is there is inside the rotor of working area.The 12 groove 10 pole rotor magnetic steel embedded actuators of the present invention, magnet steel is embedding
Inside rotor core, by adjusting the angle between magnetic links, reduce non-active area leakage field, and make the resultant magnetic field of magnet steel
Perpendicular through rotor cover；Demagnetization capability resisted by effectively protection magnet steel, and iron core effectively protects magnet steel, adds its high-speed cruising
Probability.
(3) 12 groove 10 pole rotor magnetic steel built-in permanent magnetic motors, save magnet steel consumption relative to 12 groove 8 poles, with specified
Under 48V600W model motor, use the magnetic links of 3.0mm thickness, and save magnet steel weight relative to the version of 12 groove 8 poles
Amount is about 31g.
