摘要： A centrifugal apparatus includes a rotor having a marker for generating an index signal, a motor for rotating the rotor, first and second detectors for detecting the index signal with rotation of the rotor to generate first and second detection signals, an input terminal for receiving supply power, a drive circuit for generating a drive signal from the supply power according to the first detection signal, and first and second switch circuits for controlling the supply of the drive signal to the motor. First and second judging portions are used to detect whether the first and second detection signals are respectfully generated within a given condition. The first judging portion operates the first switch circuit to stop the drive signal from being supplied to the motor when the first detection signal is not generated within the given condition, while said second judging portion operates the second switch circuit to stop the drive signal from being supplied to the motor when the second detection signal is not generated within the given condition. The first and second detectors, judging portions, and switch circuits, respectively, independently operate to provide double feedback loops, so that an overspeed or the like is prevented.

摘要： Even when a transient decrease has arisen in a battery voltage VBAT of a battery pack at startup of a motor that drives a flywheel, a power terminal Vcc and a reset terminal RES (or an input terminal IN of a reset IC) of a microcomputer are replenished with a normal voltage by the voltage accumulated by a capacitor of the backup power circuit, and hence a controller can maintain normal operation without involvement of faulty operation. As a result, even the battery pack whose battery has a smaller amount of remaining energy can be effectively utilized as the power source of an electric driving machine.
