Can someone tell me the power (in hp or kW) the Budd Metroliner EMUs have done???
31 Westinghouse coaches 4x300hp ... 20 GE snack and 10 GE parlors 4x255hp
Traction motor hp is only valid at one speed, the tractive effort curves of these two motors might be very similar when compared over the whole speed range. The ratings are based on bench tests, in a real car the power supply and controls may not be able to give the motors enough current or voltage at every point up the speed curve. What matters to the customer is that the accelerating rate and top speed meets specification. The maker just chooses an economical motor and control combination that will do that.
