Abstract: A canned motor pump has a can separating the rotor and the fluid compartment of the pump from the stator. The stator winding is affixed to a winding carrier which is shoved over and in heat-conducting relation with the can. The casing carries the electronic circuitry for commutating the motor and this circuitry is connected with the stator winding via a plug connector on the carrier.

Abstract: A motor has a rotor rotatable about an axis, a can surrounding the rotor and having an outer surface, and a plurality of outwardly projecting stator supports fixed on the outer surface, and respective stator windings mounted directly on the stator supports. The stator supports project radially of the axis and there are at least three and at most twelve such stator supports and they are angularly equispaced about the axis.

Abstract: A cooler for the water circulation system of a combustion engine has a motor driven pump mounted directly on the cooler and connected via a flat surface with a plate provided with a three-way valve. The flat surface has an inlet and outlet connected to the plate.

Abstract: The invention relates to a latent heat storage system for use on the cooling-water circuit of a vehicle combustion engine, whereby a motor-driven rotary pump is secured either at the edge of the storage system housing or inside said housing.

Abstract: A protective device for an electrical consumer disposed in a consumer circuit. The protective device has sensor elements for detecting an operating state of the electrical consumer, and an electronic evaluation and control unit operatively connected to the sensor elements for evaluating and controlling the operating state of the electrical consumer detected by the sensor elements. The protective device further includes a protective switch responsive to the operating state of the electrical consumer for interrupting the consumer circuit. The protective switch comprises a control circuit including a bimetallic strip and a temperature-dependent resistor for deflecting the bimetallic strip for interrupting the consumer circuit, the bimetallic strip thereby defining a deflecting direction. The protective device further includes a power supply unit for supplying electrical power to the sensor elements, the evaluation and control unit and the protective switch.
