Abstract
A winding lead-acid battery comprises a group of electrode plates formed by winding the ones with strip separators 22 inserted between strip thin-plate positive electrode plates 21 and strip thin-plate negative electrode plates 20 and soaked in an electrolyte, and is used as a power source of the electric power steering system. In a motor, plate-shaped conductors are used for a wire connection ring 116 that electrically connects a cable 162, and leads multiple-phase AC power to a stator coil 114 to the stator coil 114. The motor is used as an electric steering motor. To provide a highly efficient, highly reliable electric power steering device.
