In the paper we will consider the design of a 45kW motor commissioned for a small family hatchback - the Rover Metro Hermes. The motor was designed to give rated power from 3600 - 12000 Rpm at a terminal voltage of 150 VAC. The unit has been tested on a dynamometer over the full envelope of performance and methods for improving the accuracy of measurement will be discussed. The results presented show a machine with high load efficiency up to expectations. The part load efficiency is substandard and we believe is caused by high iron losses. We will review factors considered important in minimising losses and hope to present figures at the conference of a corrected machine. We will conclude the paper with some observations on control systems for Brushless DC motors.
