A microprocessor-based ultra-high speed brushless homopolar inductor motor drive system (HiDrive) with no gearing and using a high frequency IGBT inverter switching at 32 kHz is described and discussed in this paper. The homopolar motor features a solid steel rotor without magnets, windings, or laminations, which allows the motor to be operated at very high speed. The HiDrive system achieves 16,000 RPM, 45 Hp continuously. The drive system discussed in this paper can be used to replace conventional motors and speed increasing gear boxes in very high speed industrial applications such as centrifuges, compressors, blowers, pumps, and machine tool spindles. The HiDrive system discussed in this paper is used to drive a compressor for nuclear power application. In this paper, the detailed descriptions of the motor construction, equivalent circuit, operation and control principle are offered. The IGBT inverter drive system design and controls including motor speed sensing, load angle control, synchronization, brake control, power device switchings, and thermal issues are addressed. The simulation results various test results, and the typical application examples of the high speed drives are also presented in this paper.
