摘要： A novel high torque density double stator permanent magnet electric machine is provided. An outer stator is provided which has complex teeth and optionally can have windings every tooth or every other tooth. A rotor is provided having a plurality of magnet receivers, each with a complex topology. Magnets are provided in the rotor which are tangentially magnetized with alternating polarities and a complex topology to increase torque density. An inner stator is provided having a plurality of teeth with complex topologies. Windings are provided around every tooth or every other tooth, alternatively. Air-gaps are provided between the outer stator and the rotor and between the rotor and inner stator. The air-gap between the inner stator and the rotor is smaller than the air-gap between the outer stator and the rotor. A lower current density in certain windings improves thermal response without comprising average torque.

摘要： A permanent magnet electric generator for use in downhole applications has a rotor element rotatable about an axis, extending in a radial direction generally perpendicular to the axis and one or more permanent magnets attached to the rotor for generating magnetic fields. A stator element also extends in a radial direction generally perpendicular to the axis. A shaft is connected to the rotor and rotatable about the axis, the shaft extends through the stator. The linear distance along the shaft between the rotor and stator defines a gap that is variable and resistant to debris buildup.

摘要： The invention relates to a linear motor for a sliding door, comprising a mover assembly, a stator assembly and a controller for controlling the mover assembly to move, the stator assembly is electrically connected with the controller, and comprises two or more stators; the controller is arranged between the two adjacent stators; and end parts of the stators on two sides of the controller are provided with Hall devices. The mover assembly can move on a left side and a right side of the controller, and the moving range is increased. Furthermore, the Hall devices are arranged at the end parts of the stators on the two sides of the controller, the moving range of the mover assembly to the left side and the right side can be further increased, so that the system can adapt to a wider door opening without changing the length of the stator assembly.
