摘要： Sealing in rotary positive displacement machines based on trochoidal geometry that comprise a helical rotor that undergoes planetary motion within a helical stator is described. Seals can be mounted on the rotor, the stator, or both. The rotor can have a hypotrochoidal cross-section, with the corresponding stator cavity profile being the outer envelope of the rotor as it undergoes planetary motion, or the stator cavity can have an epitrochoidal cross-section with the corresponding rotor profile being the inner envelope of the trochoid as it undergoes planetary motion. In some embodiments, the geometry is offset in a manner that provides advantages with respect to sealing in the rotary machine. In multi-stage embodiments, the rotor-stator geometry remains substantially constant or varies along the axis of the rotary machine.

摘要： An electric motor for operating a small electric device is disclosed. The electric motor includes at least one first oscillatory motor component; an inductor for producing a magnetic field; and a first magnet arrangement including a first permanent magnet that generates a force for activating a rotatory oscillating movement (R) of the at least one first oscillatory motor component around a rotating axis (z). The at least one first oscillatory motor component and the first magnet arrangement are configured such that a magnetic reluctance torque acting between the first oscillatory motor component and the first permanent magnet operates as a righting moment for the rotatory oscillating movement (R).

摘要： A motor with reduced radial forces includes a first motor part made up of 2P permanent magnet poles surrounding a second motor part formed by a magnetic yoke having a number T of pole teeth and with an air gap between the first and second motor parts. The first and second motor parts are moveable relative to one another. Exciter coils are mounted on the pole teeth and the pole teeth are separated by pole gaps. For a motor with a number 2P magnet poles and a number T of pole teeth which do not have a common submultiple greater than 1, each of the pole teeth have a centrally located auxiliary slot facing the air gap thereby to reduce undesirable radial forces.
