The motor is characterized by reasonable magnet circuit design, simple mechanical structure, apt to flux-weakening level, convenient production-manufacturing, and the like, and realizes the synchronous operation of two permanent magnet synchronous motors in the same structure, thus causing the monomer permanent magnet synchronous motor to synchronously have performances of high speed and high powder output.
Description
Technical field
The present invention relates to a kind of motor, be specifically related to a kind of consubstantial series parallel high-speed high power permanent magnet synchronous motor.
Background technology
Separate unit permagnetic synchronous motor maximum speed is more than 15000rpm, and power output can reach more than the 200kW.Owing to be subjected to certain technical limitations on magnetic circuit and winding distribute, therefore, the present application example of high-speed high power permanent magnet synchronous motor is also rare.In order to realize bigger power output or higher rotating speed, the example that adopts two platform independent motor synchronous driving arrangements is arranged in the engineering practice, the motor of two platform independent has the feedback element of location-independent and driver separately respectively, but practice shows, make two platform independent motors realize that fully difficulty is bigger synchronously by controller.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, a kind of rotating speed height, high-power consubstantial series parallel high-speed high power permanent magnet synchronous motor are provided.
For achieving the above object, the technical solution adopted in the present invention is: a kind of consubstantial series parallel high-speed high power permanent magnet synchronous motor, comprise the housing that is provided with cooling water channel and the forward flange and the rear flange that are separately positioned on the housing two ends, forward flange is connected with main shaft by bearing respectively with rear flange, the rear end of main shaft is provided with encoder, it is characterized in that: axially be set side by side with two groups of p-m rotors on the described main shaft, correspondingly with described two groups of p-m rotors on the inwall of housing be provided with two groups of stators, be provided with shading ring between described two groups of p-m rotors.
The present invention compared with prior art has the following advantages:
Magnetic Circuit Design of the present invention is reasonable, and compact mechanical structure, simple is easy to weak magnetism speed expansion, is convenient to manufacture; Owing in same structure, realized the two permanent magnet synchronous motors synchronous operation mode, thereby the monomer permagnetic synchronous motor possessed at a high speed and the performance of high-power output simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of p-m rotor of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
As shown in Figure 1, the present invention includes housing 1 that is provided with cooling water channel and forward flange 2 and the rear flange 3 that is separately positioned on housing 1 two ends, forward flange 2 is connected with main shaft 5 by bearing 4 respectively with rear flange 3, and the rear end of main shaft 5 is provided with encoder 13; Axially be set side by side with two groups of p-m rotors 6 on the described main shaft 5, correspondingly with described two groups of p-m rotors 6 on the inwall of housing 1 be provided with two groups of stators 7, the gas length between described p-m rotor 6 and the stator 7 is 2～3mm; Be provided with shading ring 11 between described two groups of p-m rotors 6.
As shown in Figure 2, described p-m rotor 6 comprises the rotor core 9 that is connected with main shaft 5 by hole 8, and iron core 9 is made up of silicon steel sheet, is pasted with permanent magnets 10 by anaerobic adhesive on the cylindrical of described iron core 9, and the lateral surface of permanent magnets 10 is provided with fixed bed 12.Described permanent magnets 10 is made by the SmCo magnet steel.Be entwined by the carbon cloth that scribbles bonding agent, described bonding agent is a resin material.
The present invention adopts two groups of p-m rotors 6 that are equivalent to two motors axially is installed on the same main shaft 5 of same motor side by side, and in the housing 1 of same motor, two groups of stators 7 are installed corresponding to two groups of p-m rotors 6, public position feedback element-encoder 13 is installed on the main shaft 5, utilize high-speed bus to make two drivers realize Synchronization Control, thereby the motor shaft end power output is reached more than the 300kW, and maximum speed reaches more than the 18000rpm.
The permanent magnets 10 of forming p-m rotor 6 adopts the SmCo magnet steel to make, and the SmCo magnet steel can effectively improve air-gap field intensity, reduces the weak magnetic degree of depth of controller, and the control difficulty to driver when making the motor expansion speed reduces.
Adopt the bigger gas length of 2～3mm between p-m rotor 6 and the stator 7, strengthen gas length, can weaken permanent-magnet magnetic resistance, the motor maximum speed is got a promotion.
