Thermal Analysis Of A Segmented Rotor Switched Reluctance Motor Used As The Belt-Driven Starter/Generator For Hybrid Electric Vehicles
JOURNAL OF LOW POWER ELECTRONICS(2016)
Abstract
This paper proposes a novel 16/10 segmented rotor switched reluctancemotor (SSRM) used as belt-driven starter/generators (BSGs) for hybrid electric vehicles. Thermal analysis is an important step to design the motor, since overheated windings and cores could lead to the deterioration of insulation and failure of the motor. Finite element analysis (FEA) tools, including ANSOFT and ANSYS Work-bench have been used to calculate the core loss and simulate the steady-state-thermal distribution in three working conditions, i.e., peak power condition, rated power condition and maximum speed condition. Furthermore, to more exactly simulate the thermal distribution, heat source, equivalent thermal conductivity factor of stator windings and convection coefficient in each surface of the motor are considered. Finite-element analysis results are presented at various working conditions.
