11. The motor controller controls the desired motor power. 12. BEVs use electric motors and motor controllers instead of internal combustion engines ( ICEs ) for propulsion. 13. It can be found in most power supplies, DC to DC converters, and low voltage motor controllers . 14. Designed by Gulton Industries the motor controller automatically began battery charging when the brake pedal was applied. 15. The motor returns an 88 % efficiency, with the motor controller consuming 2 % of the power. 16. An automatic motor controller may also include limit switches or other devices to protect the driven machinery. 17. Surface components include the motor controller ( often a variable speed controller ), surface cables and transformers. 18. The propulsion systems were significant upgrades featuring camshaft driven motor controllers that offered both higher and smoother acceleration. 19. Streetcars were slow, noisy, and clumsy to operate using the motor controller " stand " of the time. 20. Typically, incurred losses are around 25 percent, depending on the efficiency of the motor and the motor controller .
