摘要： A two-dimensional motor and a servo valve are provided. The two-dimensional motor includes a stator and a rotator arranged coaxially. The stator is enclosed in the rotor. The stator and the rotor are spaced along a radial direction of the rotor. A size of the stator along an axial direction is greater than a size of the rotor along the axial direction. The rotor is, without bearing support, directly connected to an external mechanism. The rotor is swung at a predetermined angle, such that the external mechanism can drive the rotor to move along an axial direction of the rotor relative to the stator.

摘要： An actuator includes a yoke extending about a rotation axis. A coil is wrapped about the yoke. A rotor having a direct axis and a quadrature axis is supported for rotation about a rotation axis relative to the yoke. The rotor has a reluctance along the direct axis that is different than a reluctance along the quadrature axis to rotate the rotor when current is applied to the coil.

摘要： A drive system for a high torque mechanical load includes a power supply, a controller, and a high torque electric motor. The electric motor includes a rotor that is oriented eccentrically relative to a stator. In one form, the electric motor has a crankshaft that transmit the torque to the mechanical load. In other variations, the electric motor includes at least two electric motor lobes with opposite stroke positions to provide a smoother output at higher speeds. During operation, the rotor is magnetically attracted to the energized electromagnet. With the rotor attracted to the electromagnet in the stator, the rotor contacts or comes in close proximity to the stator at a contact area. The close proximity between the rotor and stator at the contact area allows very large magnetic forces to be utilized to produce torque without increasing the size or weight of the electric motor.

摘要： A mechanism comprises a first Halbach cylinder having an inner cavity, the first Halbach cylinder magnetized to produce a first magnetic flux concentrated circumferentially inside the inner cavity. A second Halbach cylinder is concentrically received in the inner cavity of the first Halbach cylinder to concurrently form a rotational joint having a rotational axis. One of the Halbach cylinders is a rotor and the other of the Halbach cylinders is a stator, the second Halbach cylinder magnetized to produce a second magnetic flux concentrated circumferentially outwardly. An output is connected to the rotor to rotate therewith relative to the stator, the output applying a gravity load on the rotor, the gravity load being offset from the rotational axis, whereby the magnetic flux of the first Halbach cylinder and the second Halbach cylinder cooperatively produce a torque against the gravity load caused by the output.

摘要： One example device includes a rotor platform that rotates about an axis of rotation. The device also includes a ring magnet mounted to the rotor platform to provide a rotor-platform magnetic field. The device also includes a stator platform that includes a planar mounting surface. The device also includes a plurality of conductive structures disposed along the planar mounting surface. The conductive structures remain within a predetermined distance to the ring magnet in response to rotation of the rotor platform about the axis of rotation. The conductive structures are electrically coupled to define an electrically conductive path that at least partially overlaps the ring magnet. The device also includes circuitry that causes an electrical current to flow through the conductive path. The electrical current generates a stator-platform magnetic field that interacts with the rotor-platform magnetic field such that the rotor platform rotates about the axis of rotation.

摘要： A rotating body is rotatably supported on a holding section. The holding section includes a rotation detection unit, a torque-applying unit, and a brake-applying unit. The torque-applying unit includes an A-phase torque-applying coil and a B-phase torque-applying coil, and a resistance torque and a pull-in torque applied to a rotor (magnet) are caused to vary as a result of controlling supply of current to each of the coils. In addition, a braking force can be controlled by supplying current to a brake-applying coil included in the brake-applying unit.

摘要： An electromagnetic drive mechanism (10) comprises a rotor (50) configured to rotate within a stator (30). The rotor (50) and stator (30) have multiple poles (56, 36), wherein each pole comprises a radial inner portion (564, 362) and a radial outer portion (562, 364). The radial inner portions (564, 362) and radial outer portions (562, 364) of the rotor (50) and stator (30) have different heights, forming a step (566, 366) between the radial inner and outer portions of the rotor (50) and stator (30). This configuration allows for overlapping radial surfaces in addition to overlapping axial surfaces during operation of the drive mechanism (10), thereby increasing the total overlap area and thus the reluctance torque, and potentially improving response speed while allowing for a more compact device (10).
