An electronically controlled electric motor has, as position sensors ( ), coils ( ) which are arranged in a stator ( ) and opposite permanent magnets ( ) of a rotor ( ). The coils ( ) are produced integrally with connecting leads ( ). This allows the electric motor to be used in an environment with solvents. Furthermore, the electric motor is of a particularly inexpensive design.
