Description
Technical field
The present invention relates to rotary motor technology field, more particularly to a kind of electric rotating machine of bimorph transducer.
Background technology
With the development of motor technology and permanent-magnet material, permanent magnet rotating electric machine is with its high efficiency, high power density, high power
The advantages such as factor are widely used in drive system of electric automobile.The motor of new-energy automobile, typically to become
Speed operation, in low speed, it is necessary to which low-speed big exports；Need to keep invariable power in high speed.Low-speed big can meet
The startup of vehicle, such as accelerate, climbing.High speed invariable power disclosure satisfy that the max. speed of vehicle requires, and in high speed
Overtake other vehicles.
However, conventional permanent magnet motor (surface-mounted rotor or built-in rotor) is mostly single stator structure, air-gap field is not easy
Regulation, the requirement for meeting electric automobile low speed high torque and high-speed cruising ability simultaneously is difficult to by single motor.All it is in practice
Compromise balance is carried out to magneto low speed high torque and high speed constant power-performance in the design phase, sacrifices partial properties, and
The regulation of permanent magnetic field is carried out by weak magnetic control, realizes high speed output-constant operation performance.But weak magnetic one side is still not
It is enough to support the required big range of speeds of electric automobile, and the presence of stator current direct-axis component so that stator winding
Copper loss greatly increases, and reduces the efficiency of magneto；On the other hand, during weak magnetism speed expansion, inevitably occur
The more or less demagnetization of permanent magnetic steel, reduce the reliability of magneto.
The content of the invention
It is an object of the invention to overcome drawbacks described above existing for prior art, there is provided one kind can meet low speed high torque
It is required that and can meets the double-stator permanent magnet motor of the high rotating speed operation of motor.
The present invention is achieved through the following technical solutions：
A kind of electric rotating machine of bimorph transducer, including the rotating shaft 1 set along electric rotating machine pivot center, inside stator iron core 2,

Or other even-even pole count configurations, and the number of poles of inner side magnetic field modulation ring 3, p-m rotor 4 and outside magnetic field modulation ring 5 is protected all the time
Hold consistent.
The relative position of inside and outside two magnetic field modulation rings 3,5 and p-m rotor 4 can be adjusted as needed, when need
When wanting low speed high torque operation, the relative position of inside and outside magnetic field modulation ring 3,5 and p-m rotor 4 is adjusted so that inside stator iron
The magnet short-cut path of the heart 2, the magnetic flux that p-m rotor 4 provides interlink with outer stator iron core 6, now, outer stator iron core 6 and p-m rotor
The outside motor of 4 compositions plays a role；When high rotating speed is run, the phase of inside and outside magnetic field modulation ring 3,5 and p-m rotor 4 is adjusted
To position so that permanent magnet flux interlinks with inside stator iron core 2, and now, inside stator iron core 2 forms interior with p-m rotor 4
Side motor plays a role.Realized by adjusting inner side magnetic field modulation ring 3, outside magnetic field modulation 5 and the relative position of p-m rotor 4
The switching of inside and outside two motors, to meet that electric automobile driving etc. requires the occasion of low speed high torque and high rotating speed range of operation.
The novel double-stator rotary motor configuration, had both met the requirement of low speed high torque, had expanded the high rotating speed of motor again
Range of operation, improve the power out-put characteristic of full speed range.In low speed, to meet the big torque needed for climbing etc.,
Outer stator iron core 6 is coupled with p-m rotor 4, forms outside magneto, and it is designed to meet that low speed high torque is leading；
When high speed, by rotating inside and outside magnetic field modulation ring 3 and 5, short-circuit outer stator iron core 6 so that inside stator iron core 2 with
P-m rotor 4 couples, and forms inner side magneto, the Design of PM Motor is to meet that high-speed operating characteristic is leading.It is so low
Fast big torque and high rotating speed run two kinds of operating modes and performed respectively by outside magneto and inner side magneto so that Mei Ge electricity
Machine is obtained for the optimization of design, and higher efficiency is maintained in whole full speed degree range of operation, meanwhile, also improve permanent magnetism
The reliability of motor.
