Abstract: There is provided a magnet type brushless generator capable of particularly controlling an output voltage to be uniform even in a driving operation at a variable rpm from a low-speed rotation to a high-speed rotation. The magnet type brushless generator includes a stator 20 having a plurality of stator magnetic poles around which winding wires for generating a rotation magnetic field are wound; a rotor 30 having a first field magnet 32 and a second field magnet 34 disposed coaxially with the first field magnet 32 in an opposed manner so as to be rotatable relative to the first field magnet; and a planetary gear mechanism 40 configured to control a relative rotation position of the first field magnet 32 and the second field magnet 34.

Abstract: A power separating apparatus in an automobile comprises first detecting means for generating a first electric signal having a predetermined voltage level when an engine is actuated, second detecting means for generating a second electric signal having a predetermined voltage level when a rotated device is not actuated, determining means for generating a failure signal indicating a failure of the rotated device depending upon a condition of logical product of the first electric signal and the second electric signal when the rotated device should be actuated, and means for controlling an electromagnetic clutch to separate the rotated device from the driving belt on the basis of the failure signal.
