Abstract
A fuel supply device is composed of a rotary pump, a brush-less motor having a stator and a rotor connected to the rotary pump and a circuit unit for supplying drive current to the brush-less motor. The circuit unit has a plurality of one-chip IC units on which a plurality of switching transistors and a circuit for detecting position of the rotor are integrally formed. The stator has a plurality of phase coils each of which is connected to one of the switching transistors of each of the one-chip IC units to be supplied with divided portion of the drive current from one of the switching transistors. Each of the phase coils is divided to a plurality of parallel coils having the same phase and each of the parallel coils is connected to one of the switching transistors.
