Electric locomotives draw electrical power from the stationary resource by means of an overhead wire or 3rd rail. Some also or in its place make use of a battery. In locomotives which are run by higher-voltage alternating recent, a transformer from the locomotive converts the substantial-voltage low-present-day energy to very low-voltage higher present Utilized in the traction motors that electric power the wheels. Modern-day locomotives may use three-phase AC induction motors or immediate current motors.
Three-period motors run at a constant pace and provide regenerative braking, and so are compatible to steeply graded routes, and the first principal-line a few-stage locomotives were equipped by Brown (by then in partnership with Walter Boveri) in 1899 on the forty km Burgdorf–Thun line, Switzerland.
