Performance evaluation of a high-performance motor with thermoset molded internal cooling

This paper presents the development and the validation by testing of an electric motor with an internal cooling system produced by transfer molding. The performance of the motor and challenging areas are first partially simulated also in detail before being validated on the test bench. In order to be able to classify the results in the best possible way, a second motor with an electrically identical design, but with a state-of-the-art cooling sleeve, is built in order to allow direct back-to-back testing and comparison of the results.
