Axle Alternator

Wabtec Corp Freight Products Axle Alternator

The Bach-Simpson™ Axle Alternator is designed to translate the rotational speed of a locomotive or transit vehicle wheel and axle into an electrical signal, which represents the linear ground speed of the conveyance. The Axle Alternator is mounted on the locomotive or car truck journal box by means of an adapter and is driven by the axle through a flexible connector or pegbar. The signal produced can be used by speed-actuated devices such as locomotive speed indicators, speed recorders and transition controls.
