This essay presents the design method of applying ultrasonic levitation bearing to high-speed motor and using single supporting rotor of ultrasonic levitation high-speed motor. It adopts piezoelectric transducer, the permanent magnet synchronous motor spindle; the radiation surface of transducer and the levitation support cap of the spindle adopt the conical structure with the same taper. It ensures that the spindle is highly automatic centering when it rotates at the high speed. The test results show that the spindle runs smoothly without having contact friction noise and problems of torque fluctuation and radial vibration caused by the electromagnetic coupling, when the output power of the ultrasonic power supply is at 500w, the speed of the spindle is over 20000rpm, and the levitation clearance is more than 100nm, which is more than the sum of roughness Ra for two contact surfaces.
