Abstract
A direct current (DC) motor for operation in an external magnetic field may include a rotor which is rotatable about a rotation axis and has at least two windings, at least four continuous rotary transmitters, wherein two rotary transmitters are associated with each of the windings and are configured to supply the associated winding with direct current, an angle sensor which is configured to determine the angular position of the rotor, and a controller configured to control the current feed to at least one of the windings dependent upon the angular position of the rotor. The motor is oriented relative to an external magnetic field during operation so that the rotation axis extends transversely to the external magnetic field.
