Embodiment Construction
[0031] One embodiment of the motor control device will be described below. First, an outline of an electric power steering device equipped with a motor control device according to the present embodiment will be described.
[0032] Such as figure 1 As shown, the electric power steering system 1 includes a steering mechanism 4 that steers the steering wheels 3 based on the driver's operation of the steering wheel 2 , and an assist mechanism 5 that assists the driver's steering operation.
[0033] The steering mechanism 4 includes a steering shaft 40 connected to the steering wheel 2 , and a rack shaft 42 connected to the lower end of the steering shaft 40 via a rack-and-pinion mechanism 41 . In the steering mechanism 4 , when the steering shaft 40 rotates as the driver operates the steering wheel 2 , the rotational motion is converted into an axial reciprocating linear motion of the rack shaft 42 via the rack and pinion mechanism 41 . The axial reciprocating linear motion of t...
