Embodiment Construction

[0029] The present invention is described in detail below by means of the accompanying drawings:

[0030] 1a, 1b and 1c show a drive device as a load according to the invention in isometric, sectional and plan views. The drive comprises an electric motor with a rotor shaft 2 which is enclosed by a housing 1 . The electronics for powering and controlling the electric motor are primarily protected by a housing part 3 which has a recess 6 in which the primary conductor with one winding is placed. The return line, ie the second primary conductor, is only passed through and not wound around the drive.

[0031] The housing part 3 comprises a core 7 with a U-shaped cross section, in which a secondary winding for supplying the electronics is accommodated. Consumers can thus be supplied contactlessly by means of inductive coupling, so that the consumers are electrically separated from the primary line. The power supply of the consumer can be disconnected quickly and easily by unwind...

Abstract

The invention relates to a consumer which comprises an electric motor and an electronic circuit supplying said electric motor with power, said consumer being inductively supplied with power. A primary conductor is encompassed by a secondary winding of the consumer. Information can be transmitted to the primary conductor by the modulation of high-frequency signals on the latter.

Description

technical field [0001] The invention relates to an electrical appliance and a system. Background technique [0002] It is known that electrical consumers in industrial installations, such as electronic devices, lighting devices, drives, machines, etc., are supplied with power from the mains, in particular with 50 or 60 Hz alternating current. For this purpose, the electrical consumers are usually plugged in and electrically connected by means of expensive plug-in connectors. Furthermore, such a device or machine has a T-piece as power tap for each drive. Such a T-piece is complex to install and is expensive, especially if it has to be used with a high degree of protection in wet or even corrosion-resistant areas. Such a T-piece is also known as a distribution box and often also includes other installation components such as an emergency shut-off switch. Such T-pieces are therefore also complex and expensive, especially in terms of installation. Contents of the invention...
