Motor Tutorial Series
Application ID: 110261
This series of models demonstrates how to do advanced electric machine modeling with COMSOL Multiphysics® — in 2D, 2.5D, and full 3D with end effects included. It investigates the performance of a Permanent Magnet Synchronous Motor, as is often used in modern electric vehicles.
The motor has eight rotor poles with segmented magnets embedded in a V-shape configuration. Various combinations of either straight- or step-skewed rotors, together with straight or skewed stators, are investigated. The stator has 48 slots with a distributed hairpin winding. The nominal mechanical output power is about 240 kW (325 hp), with a torque of 460 N·m (340 lbf·ft), at 5000 rpm. The RMS phase current is 500 A and the line-to-line phase voltage is about 315 V. The efficiency ranges between 98.5% and 96% depending on study type and operating conditions, such as the temperature.
Due to the fast pace of electric vehicle development, these showcase models are distributed in a rolling release. New topics are added on a regular basis. They range from simpler topics, such as a standard auxiliary sweep over the electrical angle and a basic comparison between 2D and 3D, to more advanced topics, such as torque ripple analysis, electrostatic analysis, laminated core loss evaluation, vibrations, and electromagnetic heating.
