High speed permanent magnet motors are with merits of high rotation speed, low volume and low weight, which lead to more and more widely application. Compare with conventional centrifugal machinery equipped with gear box, the adoption of high speed motor can lead to the direct drive of the load, higher system efficiency and higher system reliability. In this paper, a high speed permanent magnet motor with rated speed 60000r/min and rated power 30kW is designed. The rotor is supported by magnetic bearings. The loss of motor is analyzed in the design and a load test is carried out.
