Utilizing the hollow axles devloped for the Advanced Passenger Train, British Rail's R&D Division has developed a three-phase induction motor which mounts inside the axle and is supplied by solid-state inverters. The aim is a relatively low power motor for use on suburban multiple-unit cars with the advantage of minimizing air gap to maximize torque and eliminate all gearing. Beyond the proposed design, due for laboratory and road tests, is an advanced motor design that would use a solid (as opposed to a cage) rotor with a diesel-alternator power source that could be controlled to maintain a high level of flux.
