Abstract: A first member has a magnet assembly that includes at least one permanent magnet pair, and a second member includes an electromagnetic coil. A control circuit controls the supply of power to the electromagnetic coil as well as regeneration of power from the electromagnetic coil. The permanent magnet pair generates its strongest magnetic field along a magnetic field direction on homopolar contact planes where first magnetic poles contact one another, outward from the center of the permanent magnet pair along the magnetic field direction. The electromagnetic coil is positioned such that current will flow in a direction intersecting the magnetic field direction.

Abstract: The invention relates to an electric synchronous machine. There is a need for a dual rotor electric synchronous machine which has a mechanism for adjusting the rotor relative angular displacement while the machine is running in order to reduce back emf. There is a need for such an adjusting mechanism which can carry high torque loads. An electric synchronous machine is provided with a housing, first and second shafts rotatably supported in the housing, each with a corresponding rotor fixed thereon, both having permanent magnet field poles. Each rotor is surrounded by a corresponding annular stator, and stator coils are wound through both stators. A planetary transmission is coupled between the first and second shafts and operable during rotation of the first and second shafts to adjust an angular orientation of the second shaft with respect to the first shaft.

Abstract: The aim of the invention is to provide a linear rotation drive wherein the oscillating torques are reduced to a minimum and whose rotation drive is devoid of axial forces. For this purpose, a magnet of the linear rotation drive is provided with sloped sections or a plurality of magnet sections is configured to give at least two sloped magnet arrangements which are symmetric to a line extending in the circumferential direction of the linear rotation drive. Oscillating torques can also be avoided by distributing the magnets across the circumference of the rotor or stator in an uneven manner. Favorable results can be obtained when the least common multiple of the number of grooves and the number of poles is as high as possible.
