Abstract
This paper presents a performance evaluation for a 250 kW – 20,000 min−1 high-speed permanent magnet (PM) motor for high-speed applications such as industrial blowers and compressors. The utilization of a high-speed motor for a direct drive system can contribute to making the system size more compact when compared to a geared system. However, this could cause the motor loss density to be high due to the high output power density in the high-speed motor. At this time, we evaluated the electrical characteristics and efficiency of the prototype 250 kW – 20,000 min−1 high-speed PM motor and measured the temperature increase by carrying out a heat run test. Furthermore, loss separation was performed to improve the efficiency and design accuracy.
