SPEED CONTROL CIRCUIT (FIGURE 21-11)
The ground speed of the vehicle is regulated by the input voltage supplied to the motor by the controller.
Although the motor operates on 48 volt input at both low and high speeds, the controller regulates ground
speed of the vehicle by shortening or lengthening the pulses to the motor. Shorter pulses result in lower
speeds and longer pulses result in higher speeds.
