P600 Motor Control Module
The Motor Control Module operates the electric pump motor with varied speeds depending on opera-
tor commands. Pulse-width Modulation provides smooth and controlled operation with maximum
battery efficiency. The Motor Controller also converts battery voltage (48 volts DC) to the user-friendly
12 volts DC used throughout the rest of the system.
