Title:
ELECTRIC MOTOR AND CLOSING OR SUN PROTECTION INSTALLATION COMPRISING SUCH A MOTOR
Document Type and Number:
WIPO Patent Application WO/2012/123575
Kind Code:
A3
Abstract:
The invention relates to an electric motor comprising a rotor and a coiled stator, the rotor comprising a shaft (21) and two disks (22a) that are rotatably fixed to the shaft and provided with permanent magnets (24), a so-called outer portion (312a, 312b, 312'a, 312'b) of the stator extending from each disk axially parallel to a rotational axis of the rotor and radially beyond same, from the axis. Said stator comprises a plurality of disjointed bars (31, 31') consisting of a magnetically conductive material, certain parts (312a, 312b, 312'a, 312'b) of which form the outer portion of the stator (30). The stator also comprises a carrier structure (32) holding the bars such that they are fixed in relation to each other, said carrier structure being mounted in such a way that it can rotate on the shaft (21), axially outside the two disks (22a). The outer portion of the stator extends parallel to the rotational axis, axially outside the disks (22a) of the rotor, up to the carrier structure.
