Patent ID: 8339088

Claim:
A motor arrangement ( 1 ) comprising: a motor ( 4 ), on which a transmitter device ( 6 ) is arranged; a regulating device ( 2 ) which is spatially separated from the motor, in communication with the motor ( 4 ) via at least one motor line ( 10 ), and controlling the movement of the motor, and a plurality of sensor devices ( 8 , 14 , 16 ) which are arranged on the motor ( 4 ) and each directly connected to the transmitter device ( 6 ) via a respective sensor connection line ( 9 , 11 , 13 ), for detecting at least one physical property of the motor, and emitting a signal characterizing said physical property and transmitting the signal directly to the transmitter device ( 6 ), wherein the transmitter device ( 6 ) is connected to the regulating device ( 2 ), and transmits an output signal representative of the physical property to the regulating device ( 2 ); wherein the motor line comprises: an exterior shielding ( 32 ); at least three power lines ( 34 , 36 , 38 ) extending within said exterior shielding, which are surrounded by an electrically insulating sheathing ( 35 , 37 , 39 ); a ground line ( 40 ) extending within the exterior shielding ( 32 ), and a control line ( 42 ) extending within the exterior shielding ( 32 ), the control line containing-two control wires ( 44 , 46 ) arranged therein, the control wires ( 44 , 46 ) being-surrounded by a second shielding ( 45 ); wherein the second shielding ( 45 ) and the exterior shielding ( 32 ) are insulated against each other, and wherein an electric contact device ( 49 ) is arranged on the second shielding ( 45 ) on at least one end of the motor line, which communicates with the second electric shielding in an electrically conducting manner.
