The use of a remote power supply for conventional induction-type electric motors
requires that very high frequency, high power pulse-width modulated signals be transmitted
through cables over a significant distance. There are losses inherent in this transmission
process as well as problems related to the electro-magnetic interference generated by these
cables and reliability issues associated with the cables and interconnects. In addition, the
current thin lamination manufacturing method for induction motors results in geometrical
restrictions, significant losses, and significant material wastes.
The development of a modular permanent magnet machine that is constructed of
identical, individual stator poles that are each closely integrated with their own power
electronics module seeks to overcome the issues currently plaguing conventional induction-
type electric motors. Combining the stator poles of a permanent magnet motor with their
own integrated power electronics module-based drive unit within a motor housing has
several advantages including increased reliability and improved efficiencies. However, this
integrated approach is challenged by the mismatch in the thermal limits between the motor
and IPEM. This thesis describes the development of computational models of the motor, air
passages, and IPEM which are integrated in order to identify and design the most attractive
thermal management system. An experimental verification follows the model results.
