Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a cross-sectional view of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of turbo-compressor that is applied to fuel cell system, it comprises magneto 100 and gas compressor 200.
The three-dimensional flow aerodynamics computer design art designs of impeller 210 uses advanced of gas compressor 200 forms.Because the delivery pressure of gas compressor 200 has direct relation with the linear velocity of compressor impeller cylindrical, so the rotating speed of raising drive motor is one of effective measures.The utility model adopts a magneto 100 as drive motor.
Magneto 100 comprises casing 7, and casing 7 adopts non-magnetic casting aluminium material to make through machining, and front cover 2 and rear end cover 10 are installed by bolt respectively in the rear and front end of casing 7.The internal fixation of casing 7 has stator 4, and stator 4 adopts low-loss cold rolling electric sheet to make.Motor shaft 3 is provided with rotor permanent magnet 5, the material that rotor permanent magnet 5 adopts is resistant to elevated temperatures Nd-Fe-Bo permanent magnet material, this rotor permanent magnet 5 is an overall structure, and adopt overall radial to magnetize, its outer installment has not magnetic conduction sheath 6 of high strength, and rotor permanent magnet 5 and high strength do not adopt interference fit between the magnetic conduction sheath 6.After the utility model energising, the electromagnetic torque that stator 4 produces drives rotor permanent magnet 5 and rotates.The rear and front end of motor shaft 3 is provided with floating-ring bearing 11.When motor shaft rotates, drive the floating ring rotation by the inner membrance shearing force, when inside and outside oil film action when the oil-film force of floating ring and friction torque reach balance, floating ring i.e. stable operation under fixing ring speed ratio, at this moment, motor shaft is in the work of floating ring inner suspension, and bearing is not easy wearing and tearing, and can bear the rotating speed of 120000rpm.
