The Design of d-c Commutator Motors for High Performance Electric Vehicles

A study has been made of the design of d-c commutator motors for high performance drives in electric vehicles. Details are given of the power/speed characteristic which the motor must provide, and of the influence on the design of quantities such as motor speed, efficiency, winding details, and weight. An outline is given of a computer program which optimizes the motor design for electric vehicle duty, and an example is given of a 40 kW traction motor which powers an electric delivery vehicle.
