<p><P>PROBLEM TO BE SOLVED: To provide an electric power steering driving system provided with a motor reduced in torque pulsation and a control device with excellent manufacturability. <P>SOLUTION: A stator core 112 of the motor 100 is constituted of a circular annular back core 112B and a plurality of teeth 112T made by being separated from the back core 112B and fixed on an inner peripheral side of the back core 112B. The relation of 8 pole-9 slot, 10 pole-9 slot or 10 pole-12 slot is provided between the number (the number of poles) of magnets 134 of a rotor 130 and the number of slots. The diameter of a stator coil 114 is more thanϕ1.0mm. The control device 200 is provided with a power module 210, a conductor module 230 and a control module 220. A terminal of the power module 210 and a bus bar of the conductor module 230 are connected by welding. The terminal of the power module 210 and the terminal of the control module 220 are connected by soldering. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
