Issah Ibrahim, Ph.D
Issah Ibrahim is an EMaG specialist at Maya Heat Transfer Technologies Limited. He holds a PhD in Electrical Engineering. His research interests include the development of numerical analysis tools such as the finite element method, the design and optimization of low-frequency electromagnetic devices with particular emphasis on electric motors EV applications, generators, actuators, and transformers. Plus their coupling to power electronic drives, as well as their thermal, structural, and vibro-acoustic analysis.
THE ROLE OF TEMPERATURE IN THE ELECTROMAGNETIC NOISE PERFORMANCE OF THE ELECTRIC MOTOR
Infinite element simulations, machine noise, is often evaluated under ideal motor conditions. But this may not be the case in practice. There are a lot of electro-mechanical processes that could go awry as the electric machine operates. Heating, for example, is a well-known phenomenon that influences the motor’s performance and longevity if the machine is not properly insulated. The existing coupled multiphysics simulation steps for calculating electromagnetic noise seldom account for temperature variations in the simulation process.
