Design of torque-dense induction motors for automotive drive applications

Abstract

This paper addresses the design of an induction motor for electric vehicle applications. The motor is required to give very high transient torque during accelerations will being efficient under steady state operation. The paper discussed the required torque-speed envelope and develops a design which is suitable. The analysis techniques includes the use of a spreadsheet design package, a finite element analysis package and a thermal analysis package. The results illustrate the use of highly saturated induction motors and high torque-dense design.

Performance Evaluation of an Induction Motor Drive for Traction Application

“…The Induction Motor (IM) represents one of the most interesting alternatives for electric traction, as widely discussed in literature and implemented in remarkable actual solutions [1]- [7]. In particular, one of the most appreciated features of this machine is its ability to work at high speeds.…”
