Abstract
PM motor is an important energy conversion system for the off-road hybrid electric truck. The motor should be operated and delivered rated power to meet the driving requirement of the truck. For the permanent magnet is sensitive to the temperature variation, this paper presents the thermal behavior of the PM motor based on lumped parameter method. The heat flow caused by the conduction and convection in the PM motor are discussed, a thermal network considering the thermal resistance of the main components of PM motor is built and investigated. The steady-state and transient thermal analysis of the PM motor are calculated. The simulated results are validated with experiment measurement.
