Product Manager – Electric Motor Design

Sumeet Singh is currently working as a Product Manager – Electric Motor Design at EMWorks Inc, Montreal. He is responsible for the product development - MotorWizard, design, and research efforts for the electric motor simulations. He received his Ph.D. degree in Electrical and Computer Engineering from Concordia University, Montreal, Canada. He has expert knowledge in 2D/ 3D design, numerical-simulation analysis, and optimization of electric motors – sizing, magnet and rotor shaping, advanced magnetic materials, electromagnetic, thermal, and stress analysis.


Torque Enhancement of Electric Motor using Asymmetrical Rotor Structure Design

The permanent magnet (PM) motor is one of the feasible solutions to the energy crisis and environmental pollution. Due to the high demands in power and torque density with overall high efficiency, the permanent magnet synchronous machine (PMSM) is mainly considered.

In this presentation, we shall discuss examples of symmetric and asymmetrical rotor structures and its concept. Then we will dive into the FEA-based simulation analysis using EMWorks electromagnetic simulation software. Finally, a comparison between the asymmetrical rotor with the conventional symmetrical rotor design for the interior PM motor will be performed under the same operating condition.
