Abstract: In a valve timing control apparatus configured to execute phase-control via a phase converter, a controller is configured to control a phase angle of a camshaft relative to a crankshaft during an engine stopping period to a target phase angle differing from a required phase angle suited for an engine operating condition. The controller is further configured to change the phase angle of the camshaft toward the required phase angle during a time period from a point of time when cranking starts to a point of time when detection of a rotational position of the camshaft initiates during an engine restarting period. The controller is still further configured to start feedback-control for the phase angle of the camshaft from the point of time of initiation of detection of the rotational position of the camshaft for bringing the phase angle of the camshaft closer to the required phase angle.

Abstract: An energization control circuit compares a target rotation direction of a motor and an actual rotation direction of a motor detected based on rotation detection sensors. If the compared rotation directions are in disagreement, the energization control circuit switches over an inverter control mode from 120-degree energization to 180-degree energization to extend an on-period of a high-side switching element of an inverter circuit to an advance phase side. Thus, the high-side switching element is turned on, when a low-side switching element of the same phase is in a turned-off state. A free-wheeling current is allowed to flow through the high-side switching element rather than through a free-wheeling diode of the high-side switching element.

Abstract: A sealing structure has a permanent magnet and a magnetic-flux guiding member for guiding magnetic flux of the permanent magnet to a brake shaft of a brake rotating member. The magnetic-flux guiding member surrounds an outer periphery of the brake shaft so as to form a sealing gap around the brake shaft. The sealing gap is communicated to a fluid chamber, in which magnetic viscous fluid is filled. A fluid sealing member is provided at the brake shaft at a housing outer side of the magnetic-flux guiding member to form an intermediate fluid chamber, in which an intermediate fluid made of non-magnetic liquid is filled.
