ELECTRIC DRIVE SYSTEM FOR MOVING A BUILDING ELEMENT WITH MAGNETIC BRAKE
An electric drive system (1) for driving an actuator of a building element (2) or a building element (2) directly. The electric drive system (1) comprises an electric drive motor (4) having a housing (10) and an output shaft (5) extending from the housing (10). A ferromagnetic core (11) is operably...

| description | An electric drive system (1) for driving an actuator of a building element (2) or a building element (2) directly. The electric drive system (1) comprises an electric drive motor (4) having a housing (10) and an output shaft (5) extending from the housing (10). A ferromagnetic core (11) is operably coupled to an extension (25) of the output shaft (5) to rotate when the output shaft (5) rotates. At least one pair of permanent magnets (12, 13, 14, 15) is arranged circumferentially and substantially equally distributed around the ferromagnetic core (11). The ferromagnetic core (11) has a number of circumferentially substantially evenly distributed radially extending teeth (9). The number of teeth is equal to the number of permanent magnets (12, 13, 14, 15) in the at least one pair of permanent magnets. |
