Abstract
An electric motor has two exciter windings, independent of each other, on a stator, by which windings a resultant magnetic field can be produced. The motor includes a permanently magnetized rotor which has at least one pair of poles, the rotor changing its position as a function of the magnetic field, and the rotor being arranged axially on a rotor shaft. In the case of an electric motor which is of a small size and easy to manufacture, the stator is developed with several arms, and has an opening present at the center to receive the rotor. The individual arms are arranged around the opening and, there are, two pairs of opposite arms. The opposite arms are so bent towards each other so that, upon their receiving a respective exciter winding, they produce magnetic vectors which are perpendicular to each other.
