A rotation angle sensor includes a sensor integrated circuit attached to an attachment member. The attachment member includes a connecting terminal protruding upward from an attachment surface and a guide protruding upward from the attachment surface and positions, together with the connecting terminal, the sensor integrated circuit at an attachment position. The sensor integrated circuit includes a lead frame on which an electronic circuit is mounted and an exterior covering the electronic circuit. The lead frame includes a lead and an extending portion located in an outer periphery of the exterior. At least one of the lead and the extending portion has an elastic structure. The sensor integrated circuit is attached to the attachment member by an elastic force of the elastic structure that biases the extending portion against the guide and that joins the lead to the connecting terminal.

A voltage command generation unit generates a voltage command value, based on a current deviation relative to a current command value. A dq-axis voltage filter generates a voltage command value subjected to a filtering process for smoothing a change of the voltage command value in a time axis direction. Then, the voltage command value subjected to the filter processing is subjected to a voltage amplitude correcting process and a dq inverse transformation coordinate converting process, so that a phase voltage command for an AC motor is generated. Thus, it is possible to prevent both an amplitude and a phase of the voltage command for the AC motor from being changed rapidly even at a time of control mode switchover.
