ABSTRACT:
A canned motor providing a rotor having a rotor shaft; a can having a cylindrical wall which is closed at one end; and a stator, the cylindrical wall of the can being inserted between the rotor and the stator. To measure the rotational position and, where applicable, the number of revolutions of the rotor, the invention provides a resolver integrated in the canned motor which has a resolver rotor that rotates with the rotor and a stationary resolver stator, the cylindrical wall of the can also lying between the resolver rotor and the resolver stator. The resolver enables the rotational position of the rotor, in particular, to be precisely measured as well as the number of revolutions, and thereby enables the motor to be regulated as basically known from the field of electronically commutated DC motors.
