Multiphysics Modelling of Electric Motors

Session 2C - Multiphysics Modelling of Electric Motors

Dr Tao Yang

Development efforts to meet the demand for electric motors and generators have increased exponentially with the transition to electric vehicle production. Modelling and simulation is an integral part of the R&D process in the field, enabling engineers to address design considerations such as the:

• Demand for electric motors to deliver high torque across a broad speed range

• Limited availability of essential minerals

• Aim to minimise heating and noise generation

COMSOL Multiphysics® offers extensive capabilities for modelling, simulating and optimising radial and axial flux machines using different principles of operation, such as permanent magnet, switched reluctance and induction machines. COMSOL’s unique ability to handle nonlinear magnetic effects in combination with temperature-dependent properties and heat transfer has made it the preferred product for creating high-fidelity multiphysics models.

In this session, we will demonstrate the COMSOL® software's capabilities for analysing rotating electrical machines such as motors. We will show how the software treats nonlinear magnetic effects such as hysteresis as well as temperature-dependent properties.
