A motor controlling device includes an encoder to output pulse signals with a predetermined angle interval as a rotor of a motor is rotated. An energized phase of the motor is sequentially switched by detecting a rotation position of the rotor based on a value of counting the signals. An initial drive controlling portion executes an initial drive to switch the energized phase with a predetermined pattern after the device is activated so as to learn a relationship among the count value, the rotation position and the energized phase. An initial drive prohibiting portion prohibits the execution of the initial drive until a predetermined time is elapsed after the initial drive is finished.

A shift-by-wire control system includes a parking lock device that brings an output shaft of an automatic transmission device to a lock state when a range switching unit switches to the P-range. The parking lock device brings the output shaft to a lock-release state when the range switching unit switches to another shift range. An electric motor actuates the range switching unit and the parking lock device in accordance with an instruction of an operator. A manual device transmits manual operation force of the operator to the parking lock device when the electric motor stops. The manual device includes a one-way transmission unit permitting transmission of the manual operation force in a direction toward the lock state, and prohibiting transmission of the manual operation force in a direction toward the lock-release state.

A thin plate 80x forming a stator tooth 80 has two convex portions 83 on each of side faces 80b, 80c. Four convex portions 83 are a sharpened convex portion 83a of which a tip portion has a thickness thinner than a thickness of the thin plate 80x. When a bobbin 81 wound with an exciting coil 22 is press-fitted around the stator tooth 80, four lines of convex portions formed by laminating the thin plates 80x cut in an inner wall of the bobbin 81, the strength for fixing and holding the bobbin 81 can be increased in a radial, lamination and rotating directions, so that the position of the bobbin 81 assembled in a right position can be maintained.
