In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.
A brushless dc motor needs several voltage levels to control its speed: 0V to stop the motor, 5V to run it at maximum speed, and some voltages between these extremes to run it slower. When you use ...
