Abstract
An electric motor (100) for operating a shutter or solar protection element in a building, comprising at least two phases (10; 20, 30; 50, 60) and a magnetized rotor (16; 40; 70) common to both phases, each phase being relative to a rotor portion (41, 42; 71; 72) in the direction of the axis of the rotor and comprising two windings (14, 15), wherein each phase comprises an insulating yoke frame (13) on which the two windings are produced and which has a central portion (131) separating the windings, the central portion being provided with a first through-recess (134) able to surround a rotor portion passing through the phase.
