Guest Editorial Design and Optimisation of Electric Motors for Transport Electrification

Electric traction drives have seen increased application for road, rail, marine and aerospace transportation to provide improved performance and to reduce emissions. They generally consist of a dc power source, a power electronic converter and an electric motor. The electric motors used in such applications require high power density to achieve small size and weight, high efficiency to reduce energy consumption, high reliability to reduce maintenance and a wide constant power speed range to minimize the need for variable gearing between the motor and the wheels.
