Design of a Traction Motor With Tooth-Coil Windings and Embedded Magnets

Abstract

He became an Associate Professor of electrical engineering in 1993 and a Professor of electrical machines and drives in 1997 with LUT. He is currently the Head of the Department of Electrical Engineering, LUT, where he is engaged in research and development on electric motors and electric drives. His current interests include different synchronous machines and drives, induction motors and drives, and solid-rotor high-speed induction machines and drives.

Design of a traction motor with two-step gearbox for high-torque applications

“…2. Detailed information of the design process of the traction motor has been given by the authors earlier in [6], [7]. Now one can calculate the needed acceleration according to Newton's second law when the mass, gear ratio and inertia coefficients are known.…”

Optimal Design of an Axial-Flux Permanent-Magnet Motor for an Electric Vehicle Based on Driving Scenarios

“…For example, Kahourzade et al [1] discussed a comprehensive design of a 10-kW axial-flux permanent-magnet (AFPM) motor for an EV direct drive based on the power and torque requirement. Lindh et al [2] designed an interior permanent-magnet synchronous motor (PMSM) for traction application to meet the requirements of torque and speed (TN) under the constraints of voltage and current using an optimization process; however, the resulting torque and speed curve was determined by tuning the number of turns, the torque, and the current ratio. One drawback of the traditional motor design is that a close relationship does not exist between the TN curve and the motor parameters.…”
