Description
Technical field
This utility model is related to electro-mechanical arts, more particularly to a kind of 45 groove fractional-slot permanent-magnet synchronous low voltage motor.
Background technology
The stator of general traditional small generator or motor is all using integer groove, only high-rating generator or electronic
Machine uses fractional-slot, and the fractional-slot of prior art motor stator all to apply in high-voltage motor, has following reason and advantage：
If 1. adopting integer groove, it is the sine for keeping potential waveform, and less cogging torque then must be using fixed
Sub- skewed slot, generally an oblique tooth pitch or slot pitch t1, but in high-voltage motor, as coil is rectified type winding for molding, in integer groove
In the case of, if stator entirety skewed slot, coil twists an angle in groove, it is impossible to contact grooved well, its high-tension coil
Can not be grounded well, and produce galvano-cautery and impact is produced on coil life.
2., in the case of high-voltage motor especially uses odd bin simultaneously using fractional-slot, skewed slot or few oblique can not be used
Groove, by making, above-mentioned processing performance is greatly good, while various sinusoidal wave forms all will be best.
3., as the way in parallel of fractional-slot is few, only 1 road to most 2 tunnels parallel connection mostly is selected, using in coil turn
Improper in less motor, and electromotive force of the high-voltage motor for needed for making to reach, the number of turn is more, without the need for more parallel connection roads
Number, is adapted to this occupation mode just.Due to the common asynchronous low voltage motor number of turn it is few, it is less and around root to make it have
Number, only increases more and around way.
Due to above reason, fractional-slot is played without in low voltage motor application than a variety of advantages of integer groove.
Utility model content
Technical problem to be solved in the utility model is to provide small volume, and efficiency high is pulsed little, and prevents magnetic flux short
The 45 groove fractional-slot permanent-magnet synchronous low voltage motor of one kind on road.
This utility model is to be achieved by the following technical programs：
A kind of 45 groove fractional-slot permanent-magnet synchronous low voltage motors, including stator core and be socketed with rotating shaft and synchronous turn with rotating shaft
Dynamic rotor core, the stator core are set in the periphery of rotor core, and 45 magnetic are evenly equipped with the stator core section
Pole groove, the inside of the rotor core are embedded with 4 permanent-magnet poles, and the way in parallel of the permanent-magnet synchronous low voltage motor is 1, described
The on line mode of permanent-magnet synchronous low voltage motor is AAAAZZZZBBBBXXXCCCCYYYYAAAAZZZBBBBXXXXCCCCYYY.
The beneficial effects of the utility model are：
The 45 groove fractional-slot permanent-magnet synchronous low voltage motor of one kind that this utility model is provided, it is uniform on the stator core section
The inside for having 45 magnetic pole grooves, the rotor core is embedded with 4 permanent-magnet poles, the way in parallel of the permanent-magnet synchronous low voltage motor
For 1, the on line mode of the permanent-magnet synchronous low voltage motor is
AAAAZZZZBBBBXXXCCCCYYYYAAAAZZZBBBBXXXXCCCCYYY, is embedded in 4 permanent magnetism using inside rotor core
Pole, can effectively prevent magnetic flux short circuit, the magnetic flux needed for being provided by permanent magnet from providing any excitation point without the need for armature winding
Amount, is applied in permanent-magnet synchronous low voltage motor using fractional-slot, by the cooperation of the slot number chosen and number of poles, is equipped with appropriate short
Away from double-deck lap winding, less than the asynchronous machine of a same specification seat No., compared with Y2, rated efficiency improves 4%, and
More than 90% high valid value can be kept under 40% to 80% load factor, due to the permanent-magnet synchronous low tension under each operation angle
All can be staggered between machine magnetic pole and groove an angle, therefore skewed stator slot can be reduced to minimum, not even using skewed slot, enter
And greatly improving winding coefficient, stock utilization also increases, and manufacturability also strengthens therewith, makes motor operation more steady.
