摘要： An electric power steering apparatus is provided that has a controller by which no current flows in one phase among current paths of three phases for supplying electric power from a motor driving circuit to a three-phase brushless motor and currents that have an identical absolute value and that have different signs flow in the other two phases. Thus, the status at one energization angle on the driving current waveform of the three-phase brushless motor can be given continuously and relatively-high currents can simultaneously flow in opposite directions in the contacts inserted to the two phases. By flowing of such high current in the contacts, a secure conduction check can be performed and foreign matters on the surface of the contact can be fused or thermally destroyed.
