Disclosed is an electric motor that includes a stator with a plurality of main poles, each of which includes a coil, and a rotor rotatable about an axis and having a magnet with magnetic po?es in which N and S poles are alternating The motor further includes a first sensor group of a plurality of magnetic sensors fixed relative to the stator, and a second sensor group of a plurality of magnetic sensors fixed relative to the stator When operating the motor, the first sensor group can be selected so as to rotate the rotor in a first direction The second sensor group can be selected so as to rotate the rotor in a second direction opposite to the first direction. |
