Experimental Drive Performance Evaluation of High Power Density Wound Field Flux Switching Motor for Automotive Applications

Abstract

This paper presents experimental drive performances evaluation of wound field flux switching motor for hybrid vehicle drive applications. A test machine with the maximum torque of 210 Nm and the maximum power of 123 kW expected at its design stage is built. A various experimental test result is demonstrated from viewpoints of the maximum torque and the maximum power capabilities and the motor efficiency up to its base speed of 6,000 r/min. As a result, it is confirmed that the test machine promises well as a machine with very high power density more than 4.2 kW/kg at the maximum power point under water jacket cooling.
