摘要： A heat engine (10), particularly a heat pump, has a first heat exchanger (11), a compressor (12), a second heat exchanger (13), and a throttle device (14) connected by a refrigerant line (15), through which a refrigerant flows, and electronics (21, 22, 23) with power electronics for supplying power to and/or control electronics for controlling the heat engine (10). A heat transfer mechanism (24) absorb at least thermal energy emitted by the electronics (21, 22, 23) and transfer it to the refrigerant and/or, insofar as one exists, to a system medium flowing through the first or second heat exchanger.

摘要： An analog circuit arrangement (1) to variably set a voltage Uout, within defined voltage limits, has a non-inverting adder (10) with a positive input (11). A voltage divider (20), with at least a first stage (21) and a second stage (22), is connected to the positive input (11) of the adder (10). At least one stage has a parallel circuit of n resistors (R1, R2, . . . , Rn) that are each connected in series in a conduction path (L1, L2, . . . , Ln) to an overcurrent protection device (F1, F2, . . . , Fn). At least one device (30) actively changes one or more of the overcurrent protection devices (F1, F2, . . . , Fn) into a state that interrupts the respective affected conduction path (L1, L2, . . . , Ln).

摘要： A centrifugal fan (1) has a fan unit (10) with an impeller (11), a motor (12) for driving the impeller (11), and a support structure (13) for securing the fan unit (10) in the intended detachable manner to a flange plate with an intake opening (21, 22). The support structure (13) is designed to hold the fan unit (10) on the flange plate (21, 22) by itself. A plurality of air guide segments (23), that together form a downstream guide device (20), are secured to the support structure (13) and/or to the flange plate (21, 22).

摘要： A switching disk for contacting windings of a stator of an electric motor, which windings are arranged around an axis of rotation, with a printed circuit board of the electric motor, wherein the switching disk has an annular support structure circumferentially extending around the axis of rotation and multiple contact arrangements for contacting the windings with the printed circuit board, which are held by the support structure. The contact arrangements are each formed by a winding contact for contacting one of the windings, a printed circuit board contact offset therefrom in the radial direction for contacting the printed circuit board, and a coupling element extending in the radial direction and electrically connecting the winding contact to the printed circuit board contact.

摘要： A 3-strand rotating field machine with a 2p-pole stator with winding teeth (Z), formed with a winding arrangement in tooth coil technology, has three winding strands (W1, W2, W3). The winding arrangement is formed from wound coil groups (G) with coils that are multiply interleaved. The partial coils (T) of the coil groups (G) are arranged so they concentrically enclose one another from inside to outside and surround two or more winding teeth (Z). The respective coil winding numbers in the grooves (N) between the winding teeth (Z) are provided. Thus, in each case a substantially equal occupancy of each groove (N) is provided with the same effective total conductor cross section of the coils per groove cross section.

摘要： An impeller with impeller blades arranged around a rotational axis of the impeller. Integral, seamless, and notch-free transitions are formed into a disc body on at least one of their two axial sides. The disc body connects the impeller blades in the circumferential direction around the rotational axis. Covering portions, between the impeller blades, determine the flow channels of the impeller.
