Normally a brushless motor controller requires the use of a complex system of multiple, isolated power supplies to operate the high power output transistors which drive the motor. This invention simplifies this using a single split-rail supply A-B-C comprising a low power supply A-B which powers the controllers and high power supply B-C which powers the brushless motor F. The positive connection of the high power supply is shared with the ground connection of the low power supply. This invention provides a method of powering the brushless motor and controller from the same power supply thus decreasing complexity and ultimately cost
