Abstract

The rigid axle joining two train wheels is of a wide diameter with hollow interior. The axle forms the rotor of a high torque electric motor, with the stator mounted inside the axle and supported through either side of the assembly on a hollow shaft. The shaft is coupled to the wheel mountings via an epicyclic gearing for a reduction effect. The hollow tube serves as a cooling duct for the high torque motor. The motor used can be an AC caged rotor or an induction motor with an unlaminated rotor and supplied from a three phase supply. The compact, high speed motor requires no further special mounting, or long gear train coupling to the wheels.
