An asynchronous linear machine (ALIM) has been designed as a booster to support the traction motors of electric locomotives under wet weather conditions, when the mechanical force of the wheel-rail contact is reduced. The booster shall provide additional accelerating and braking forces and an attractive force between wheel and rail. Fed by an inverter, which is mounted on the loco, the braking, accelerating and attractive forces are generated independently of train speed, being only determined by voltage and slip. Nevertheless, several draw backs are foreseen with the ALIM. Due to the restricted space small winding overhangs have to be chosen, which is difficult with three-phase windings. The low conductivity of the rail and the rather large air gap of 6.5 mm yield a huge amount of magnetising current and a rather low force production. Analytical and numerical calculations are presented in the paper and conclusions are drawn.
