Abstract :
The paper comprehensively describes the design process of a 60 kW, 9000 rpm, totally enclosed, water cooled PM synchronous machine. PM machine technology is a rival choice for higher-speed applications ruled normally by traditional or solid-rotor induction machines. PM technology offers several advantages on higher-speed applications compared to IM solutions - a high torque density, small size and high efficiency. The complexity of the rotor and the poor temperature tolerance of the magnets are the main disadvantages of the rotor type.
