A battery pack with at least two electrochemical cells, lithium ion cells in particular, has each cell including a positive pole and a negative pole on the end face of the particular cell body, the poles of the cells being electrically connected in series and/or in parallel. A cell connector for electrically connecting the cells is provided on at least two cells, on the end face on the same side relative to their position in the battery pack, the cell connector connecting one pole of the connected cells and extending to a contact region of a circuit board; the cell bodies of the cells are positioned parallel to each other, and the end faces of the cell bodies are located in the same plane.

Battery pack and battery module and method for operating a battery module

In an electric power tool and a method for operating an electric power tool, a torque limitation of an electric motor reacts when a load moment exceeds a predetermined threshold and in which an output request is carried out by means of a switch. A supply of current to the motor is interrupted when a criterion for the reaction of the torque limitation is detected based on a speed detection of the motor.

Electric power tool and method for operating same

The invention relates to a brushless DC machine comprising a rotor and a stator that supports a winding assembly. The stator encompasses a toothed rim with tooth tips that extend radially outward as well as a return ring. The toothed rim and the return ring are embodied so as to engage into each other in a radial direction. The invention further relates to a return ring packet, a toothed rim packet, a top piece, and a method for producing a brushless DC machine.

A gaseous-discharge lamp, in particular for motor-vehicle headlamps, includes a burner vessel made of glass or the like that contains a gas. Into this burner vessel extend two main electrodes via two gas-tight electrode bushings. Between the end regions of the main electrodes arranged in the burner vessel, an arc gap is formed, along which an electric arc develops during operation. To achieve a smallest possible ignition voltage, an arrangement is provided for producing a creepage spark gap along the inner vessel wall and/or a spark gap that is shorter than the arc gap, serving as an ignition gap that is spatially separated from the arc gap.

An arrangement for protecting a control device for gas discharge lamps from overtemperature contains a control device and a DC/DC converter. Regulation of the power conveyed to the gas discharge lamp is performed. The output value of the power controller (to be considered the manipulated variable) and the input value of the power controller (to be considered the setpoint) are ascertained by way of the control device. The ratio of these two values (manipulated variable to setpoint) is determined. The value determined for that ratio can be used to limit the output power of the control device. The control device may contains a microcontroller, and the controller is provided as a program in the microcontroller and is implemented as software in order to limit the output power of the control device.

Overheating protection device for a control device in gas discharge lamps

Proposed is a gaseous-discharge lamp, in particular for motor-vehicle headlamps, comprising a burner vessel of glass or the like having at least two electrodes, the burner vessel being provided with a lamp base that includes the electrical terminals and that is insertable into a lamp base socket. Arranged in the lamp base is an electronic ballast unit that supplies the lamp with the necessary ignition and maintaining voltage. By accomodating the balast unit in the lamp base, one can achieve a small-volume gaseous-discharge lamp having short high-voltage leads i an integrated type of construction, making it possible to keep the ignition voltage to a minimum.

A discharge lamp has a base with a burner having a discharge vessel with at least two electrodes and a supply conductor extending from the base to one electrode as well as a return conductor extending from the other electrode to the base, wherein the supply conductor is surrounded in the burner by a glass tube while the return conductor extends outside the burner along it, and between the surface of the supply conductor and an inner surface of the glass tube a distance is formed by an air-filled space and retained as low as possible or preferably at least approximately zero, so that the intensity of an electrical field formed between the supply conductor and the return conductor is low and the return conductor can be guided along near the burner, which makes possible a compact construction of the discharge lamp or the use of a high ignition voltage for the discharge lamp and/or its operation at high altitudes without the danger of partial discharges in the glass tube or ark-overs outside the discharge vessel.

Electric motor drive

A device for detecting the movement of a movable component in that the position signals furnished by two position sensors are added to form a signal that is conducted through a line to an evaluation arrangement. The position ranges associated with the position sensors have an overlap region. Different discrete values are assigned to the position signals and can be evaluated easily in the evaluation arrangement.
