摘要： A controller for a brushless direct-current motor having an upstream converter, which has a half-bridge having a pair of switching means for each phase winding of the motor, includes a measuring device or has a signal connection to a measuring device. The measuring device is associated with a half-bridge and by means of the measuring device, the induced voltage, the counterelectromotive force of a phase winding, can be detected for rotor position detection in the current-free state, for which purpose the controller, in an operating mode that causes the braking and in which the switching means cause a short circuit of the phase windings, briefly opens the switching means associated with the measuring device in order to determine a rotor motion.

摘要： A drive controller that controls a drive of a motor. The drive controller performs a collision force moderation control during a motor start time, during which a collision force in a collision between a shaft outwall with an impeller hole inwall for a positioning is moderated, by changing a power supply at a stage transition time of transiting from a position detection to a position determination. The maximum value of a first output value during a position detection time is set to be greater than a first threshold that at least causes a rotation number of the motor to yield a detectable induction voltage. A second output value during a position determination time is set to be lower than a second threshold that causes a wear or a breakage of an impeller by the collision force.

摘要： A locking device includes an integrated circuit board specially shaped to fit the locking device and to bring a sensor on the circuit board adjacent to a moving lock component. The circuit board is preferably routed to form a convex shape that matches the locking device and provides printed circuit wiring to connect one or more sensors or other components to an external wiring harness, thereby reducing point-to-point wiring within the lock. Multiple different circuits may be provided on the same circuit board, which are automatically selected by the connectors used on different corresponding wiring harnesses and/or actuators. The design reduces assembly costs and allows rapid electrification of existing mechanical locking devices with minimal modification.

摘要： Even when an overvoltage suppression circuit is not formed due to failure of an overvoltage suppression switch, overvoltage application to semiconductors and a filter capacitor is prevented. A control unit controls the overvoltage suppression circuit to short-circuit the filter capacitor when the voltage thereacross exceeds a predetermined value. Then when non-operation of the overvoltage suppression circuit is detected, the control unit opens an AC breaker and AC switch, and closes a charging switch. Thereafter, the control unit turns ON the converter element (or converter element) connecting to the filter capacitor terminal (or terminal) and a charging resistor, and turns ON converter element (or converter element) connecting to terminal (or terminal) of filter capacitor and connecting to the terminal of the transformer not connected to charging resistor.

摘要： The present disclosure relates to an intermediate circuit for an EC motor, comprising at least two similar series-connected capacitors for the connection of an electronic commutation device of an EC motor for nominal operation at a nominal voltage. In each case, a varistor is connected in parallel to each series-connected capacitor, wherein all the varistors are designed similarly. The capacitors and the varistors are dimensioned so that the threshold voltage of the varistors is less than the breakdown voltage of the respective parallel-connected capacitor, and, in the case of the failure of a capacitor or of a varistor, the sum of the threshold voltages of the remaining varistors is smaller than/equal to the nominal voltage of the intermediate circuit, and the sum of the threshold voltages of the series-connected varistors is greater than the nominal voltage of the intermediate circuit.
