Description
Technical field
The utility model is related to magneto field, more particularly to a kind of surface convex type magneto.
Background technology
In recent years, it is higher and higher to the performance requirement of motor with the continuous development of China's industrial level, via originally
Extensive style become it is detailed-oriented.For motor, in the application of industrial system, have to its efficiency, vibration, noise
Higher standard.Induction machine is a kind of maximum motor of present dosage, and designing technique has also been mature on the whole, right in country
Under the background that motor performance requirement is continuously improved, although can also realize, its design difficulty is high, stock utilization is low, further
The profit of motor manufacturing enterprise is forced down.The appearance of magneto solves the problems, such as this well, by using high performance
Magnetic material, with can obtain smaller motor volume, higher power factor and efficiency under power and also China possess it is abundant dilute
Soil resource on Development Permanent Magnet motor, there is advantageous advantage.
Due to the presence of permanent magnet in magneto, a large amount of harmonic wave can be generated in air gap, this can bring ten to motor
Divide serious influence, how reduced harmonic becomes the problem for perplexing design of electrical motor personnel.In addition, motor user always wants to
In the case where obtaining equal performance, use is small, light-weight motor.
Invention content
In order to solve the problems such as existing magneto harmonic wave is more, weight weight, it is low that the utility model provides a kind of light weight
Harmonic wave magneto.
Light weight low harmony wave magneto, it include stator, rotor, shaft and casing, further include left end cap, right end cap and
Bearing.
Rotor includes magnet steel, flux density regulating tank, lightening hole.
The motor stator and rotor are respectively positioned in casing, and stator is fixed on casing inner wall.
Rotor is fixedly connected by being interference fitted with shaft；There are air gaps between motor stator and rotor.
The motor stator, rotor, left end cap, right end cap, casing are coaxial.
Rotor is surface convex type, on the gap between magnet steel, i.e. rotor core exterior surface, is provided with flux density tune
Save slot.
Lightening hole is provided with inside rotor.
One group of flux density regulating tank is 3 slots, one of them is large trough, and another two is the identical sulculus of size.
Flux density regulating tank group number, lightening hole number are identical with magnetic steel of motor number.
The advantageous effect that the utility model is brought is that the light weight low harmony wave magneto that the utility model is proposed is turning
Groove is provided on rotor core surface between sub- magnetic pole, these grooves, which can reach, improves magnetic structure, optimization air gap flux density
The effect of waveform, reduced harmonic.
The utility model solves the problems, such as that the existing harmonic content of such motor is big, motor performance is poor and good manufacturability plus
Work is convenient.
The utility model rotor designs exclusive Lightened structure, substantially reduces motor weight, reduces motor
Rotary inertia.
The utility model improves its dynamic property under the conditions of the electromagnetic performance for not influencing this kind of motor, makes comprehensive cost
Decline.
