Patent ID: 8461736

Claim:
An electric motor for operating a window covering element in a building, comprising at least two phases and a magnetized rotor common to both phases, each phase being relative to a rotor portion in the direction of a rotor axis and comprising two windings, wherein each phase comprises an insulating yoke frame on which the two windings are produced and which has a central portion separating the windings, the central portion being provided with a first through-recess able to surround a rotor portion passing through the phase, wherein each phase comprises a magnetic circuit consisting essentially of: a first module and a second module arranged facing one another on the yoke frame, each module being in the form of an E with three branches, the central branch of a module forming a stator pole and a diameter of the rotor being less than a length of the central branch, wherein each module is formed by alternate laminations and wherein single air gap remains between modules once they have been assembled, the laminations being interleaved in two areas of overlap of the lateral branches of the two modules.
