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 at least one stationary part that has a shaft and two bearing plates disposed on the shaft at a mutual spacing, and at least one rotating part that is supported so as to rotate about a rotational axis with respect to the stationary part, and comprises a bearing bush and a sleeve enclosing the bearing bush. A bearing gap filled with bearing fluid is provided between the parts and at least one sealing gap for sealing the bearing gap that extends concentric to the rotational axis. The bearing comprises at least one fluid dynamic radial bearing and two fluid dynamic axial bearings and at least one recirculation channel that connects the two axial bearing regions to each other. According to the invention, the largest radial diameter of the recirculation channel is greater than or equal to the largest diameter of the sealing gap, and the smallest radial diameter of the recirculation channel is greater than or equal to the largest diameter of an adjacent bearing plate. Moreover, additional and effective deairing of the recirculation channel is effected by a venting device. To realize improved equilibrium of pressure in the bearing gap and improved retention of the bearing fluid, the sealing gaps can be inclined, at least in sections, at an angle α, β with respect to the rotational axis, wherein the angles may have different sizes.
