Ventilator having an electrical connection device

Abstract: The invention relates to a ventilator, having an electrical ventilator motor (M) and an electrical connection device (2) for connecting electrical motor lines (4) leading to the motor (M) to external electrical connecting lines (6). The connection device (2) has a terminal box (8) mounted to a device part (12) comprising electrical contact elements (10), and has an additional connection part (14), to which the motor lines (4) are connected. The terminal box (8) is releasably connected to the additional connection part (14) via electrical plug-in connections (16).

Wiring device for an electric motor

Abstract: The device (1) has contact elements (12) connected with outer terminal conductors (4) and plugged together with counter contacts (14) by placing a switch wafer (6) on a stator (2). The switch wafer comprise two various groups of contact supports (10) such that that the switch wafer is mountable with the contact elements on a first type of stator (2a) and a second type of stator for contacting the respective counter contacts of the stator. The contact elements are inserted into the contact supports of the various groups. The switch wafer is formed as an integrated plastic mold part.

Circuit arrangement for driving an electric power switch at high voltage

Abstract: The arrangement has a non-controllable semiconductor valve (9) e.g. diode, used for transmission of switching energy and desired switching condition of a power transistor on a high voltage potential, where an input signal (A) provides a switching information for a switching power semiconductor component (1). The semiconductor valve is implemented as a component with high withstand voltage for transmission of the information.

Method for controlling a firing device and firing device

Abstract: The firing equipment has means for determining a value dependent on a measured temperature produced by the equipment and also means for regulating the generated temperature by using a characteristic line representing a value range corresponding to the ideal temperature in dependence on a first parameter corresponding to the burner power. A second parameter corresponding to a ratio of air volume to quantity of burner medium in a mixture of air and burner medium to be supplied to the burner is constant in the characteristic line so that a first parameter is produced corresponding to a specific burner power. The firing equipment has a device in the region of the burner flame (13) to measure the temperature produced by the firing equipment.

Rotor and electric motor with such a rotor

Abstract: The rotor has a base body (2) comprising a cylinder-shaped peripheral wall (3) and a front-sided covering wall (4) that is connected with the peripheral wall in a longitudinal direction by using an outer wall transition section. A rotor shaft (5) is centrically connected with the covering layer and projects axially into a rotor area (6) surrounded by the peripheral wall. The base body and the rotor shaft are manufactured as a single piece from an aluminum alloy, where the rotor shaft is partially designed as a hollow shaft in an area running out from the covering wall. An independent claim is also included for an electric motor comprising a rotor and a stator.
