摘要: The canned motor in accordance with the invention comprises 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.

摘要: The invention relates to a fluid dynamic bearing system that comprises a bearing sleeve having a bearing bore and a shaft that is rotatably supported in the bearing bore by means of a fluid dynamic radial bearing. An annular first bearing plate connected to the shaft is provided that, together with a first end face of the bearing sleeve, forms a first fluid dynamic axial bearing, means of producing an axial counterforce to the first axial bearing being available. According to the invention, the axial counterforce is applied by means of a combination of a mechanical spring element and a second fluid dynamic axial bearing. Since the spring force of a preloaded spring does not change significantly over small distances, compensation for tolerances is made possible without the bearing system losing its axial stiffness or being subjected to too much stress.
