Detailed description of the invention
Accompanying drawing 1 is that a kind of mix suspending formula disk non-contact ultrasonic motor structure of providing of the utility model embodiment is concreteSchematic block diagram. Be mainly under based on mix suspending power effects such as acoustic pressure power, permanent magnetic and electromagnetic forces, utilize Piezoelectric Ceramics ExcitationThe motor revolving mode forming and the mix suspending formula disk non-contact ultrasonic motor developed. System is mainly by following componentsForm: motor stator, rotor, journal bearing stator, journal bearing rotor, cod stator, cod rotor andBearing. As seen from the figure, motor stator is made up of motor stator matrix 1 and piezoelectric ceramics 7, and motor stator matrix 1 is I shapeRound buss structure, its inner ring face is tightly placed in the outer ring face of bearing 3 convex platforms, and motor stator matrix 1 is fixed on bearing by screw 8On 3, piezoelectric ceramics 7 is along symmetrical stickup the in outside of stator round bottom face. Rotor is made up of rotor matrix 2 and rotating shaft 5, electricityMachine rotor matrix 2 is solid disc structure, and center and rotating shaft 5 fixedly mount, rotor matrix 2 and motor stator matrix 1 itBetween leave certain gap. Journal bearing stator 4 is the first permanent magnetism annulus, and the inner ring face of its outer ring face and bearing 3 convex platforms is stickyPaste, journal bearing rotor 6 is the second permanent magnetism annulus, and its inner ring face is pasted on the outer ring face of rotating shaft 5, with journal bearing stator 4 itBetween leave certain gap.
