A control apparatus for a rotary electric machine includes: operating unit for operating a DC-AC conversion circuit including a switching element so as to control a controlled variable of the rotary electric machine, the switching element selectively connects positive and negative terminals of a DC power source to respective terminals of the rotary electric machine and conduction period setting unit, in response to a rotational speed of the rotary electric machine, for setting a conduction period during which the respective terminals of the rotary electric machine, and the positive and negative terminals of the DC power source are allowed to be electrically connected therebetween via the switching element. The conduction period setting unit set the conduction period as a manipulated variable so as to reduce electromagnetic force distortion at a frequency corresponding to a resonant frequency of the rotary electric machine.

Control apparatus reducing noise coming from rotary electric machine

A linking device has a connecting member for connecting a first rotation member and a second rotation member. The connecting member is connected to the first rotation member at a first connecting point and to the second rotation member at a second connecting point. The connecting member includes a thermal deformation absorbing part between the first connecting point and the second connecting point, and is adapted to absorb a change of distance between the first connecting point and the second connecting point due to thermal deformation.
