| Text | #4060101 (Length: 339 characters) A train equipped with, say, two dc motors, is started with both motors connected in series to an external resistor. As the speed picks up, the resistor is shorted out. The motors are then paralleled and connected in series with another resistor. Finally, the last resistor is shorted out, as the train reaches its nominal torque and speed. |
