How do losses compare between Series motors and SepEx motors?
Losses in the field are a function of the square of the current (I2R). Typical losses in a Series motor field might be 0.020 ohms x 400 amps squared = 3200 watts. Typical losses in a SepEx motor field might be 0.32 ohms x 50 amps squared = 800 watts. Similarly we can expect less losses in a SepEx controller compared to a Series controller.
