摘要：

An axial field permanent-magnet brushless dc motor that utilizes tape-wound amorphous iron and an air-gap winding is proposed. Simplified waveforms and performance equations for this type of machine are presented. The machine equations and waveforms are verified with a proof-of-concept machine. No-load iron losses are compared with manufacturers data, and full-load iron losses are also presented. Output torque for rectangular and trapezoidal current waveforms are measured and compared. Machine designs from a computer program that demonstrate the possible benefits of this type of machine are presented. It is suggested that this type of machine could be considerably more efficient than induction machines and, additionally, cost competitive when a variable-speed drive is already a system requirement.
