  • Patent number: 10917027
    Abstract: Method for transferring a transport unit of a long stator linear motor at a transfer position from a first transport section to a second transport section. On each side of the transport unit, excitation magnets are arranged to interact with driving coils, and on both sides of the transport unit, excitation-magnetic lateral forces are acting on the transport unit by an interaction of the excitation magnets with ferromagnetic components of the guide structure. Method includes supplying on at least one side of the transport unit a stator current n a driving coil to generate a lateral force-forming electromagnetic force that acts on the transport unit, so that a resulting lateral force, as a sum of the acting excitation-magnetic lateral force and of the lateral force-forming electromagnetic force, on each side of the transport unit is different to produce a steering effect on the transport unit at the transfer position.

  • Patent number: 10892664
    Abstract: An electrical machine has a variable reluctance rotor, and a stator formed as an annular array of stator segments. The reluctance of the rotor-to-stator magnetic flux path varies with rotor position whereby the stator segments are magnetically energizable to rotate the rotor. The stator segments are arranged in the array such that, when energized to rotate the rotor, they produce an unbalanced force on the rotor. The machine further has a compensator including one or more balancing segments which are configured to be magnetically energizable to produce a balancing force on the rotor which balances the unbalanced force. The reluctance of the rotor-to-compensator magnetic flux path is substantially invariant with rotor position.

  • Patent number: 10879757
    Abstract: Disclosed is an electronic motor with two bearings. The motor is structured so that, when loaded, the majority of the load (e.g., a radial load) is borne by one of the bearings. The bearing that bears a greater load may be larger and, thus, better suited for a heavy load. In some embodiments, the larger bearing may include rolling elements that have respective radii larger than respective radii of rolling elements of the other bearing by a ratio of at least 1.5 (150%). In some embodiments, the larger bearing may have an outer race with a radius that is greater than a radius of the outer race of the smaller bearing by a ratio of at least 1.5. In some embodiments, the motors may include a third bearing between the two bearings. The third bearing may reduce vibration in the motor.
