Abstract: A pump for delivering a liquid, having an electric motor with a stator and a rotor arranged inside the stator. The electric motor is accommodated in an electric motor housing. The stator has two end faces and an outer peripheral surface and there is formed between the electric motor housing and the outer peripheral surface of the stator an outer fluid channel through which the liquid can be delivered. The stator has on at least one of its end faces a connection to the electric motor housing.

Abstract: A method for operating an electric motor that drives a displacement pump stage to deliver a liquid through a hydraulic system to supply the liquid to at least one consumer. A periodically repeating pressure fluctuation of the liquid that occurs during delivery operation is at least partially compensated by virtue of the rotational speed of the electric motor being manipulated in accordance with the periodically repeating pressure fluctuation.

Abstract: A meat grinder, having a housing, a conveying device, and at least one cutting-unit part. A meat grinder according to the invention comprises a housing, at least one conveying device for conveying material to be ground from an inlet opening to an outlet opening, and at least one cutting-unit part arranged in the housing. At least one transponder is arranged in or on the at least one cutting-unit part and at least one communication device for communicating with the transponder is arranged in or on the housing in such a way that data exchange between the communication device and the transponder is enabled.

Abstract: A bus system that has at least two lines. A bus subscriber has at least one connection element that has at least two contacts that can each be connected to one of the lines. An address allocation device can be used to ascertain an address for the bus subscriber in the bus system on the basis of a respective connection state of the contacts with respect to the lines. Also, a method allocates addresses in the bus system.
