Abstract

This work investigates the potential for cooling a radial permanent magnet motor by means of stator lamination fins. To form the fins, certain stator laminations have a larger external diameter. The optimal number of fins, as well as fm thickness, was determined to reach the maximal heat transfer between the motor stator and the coolant. Finite element and computational fluid dynamics modelling were used to calculate the thermal performance of the motor.
