This invention presents a highly efficient electric motor which can be embodied in several configurations, including a standard motor, a hub motor, a linear motor, or other motor configuration. As a regenerative device, the motor may also act as a part-time or full-time electrical generator. There is provided a motor composed of a stator and a rotor. The stator has an array of coils arranged therein. The rotor has an array of magnets arranged therein. Each of the coils includes a first winding of wire wrapped around a core, and the wire has a non-circular cross-section. The wire can be a flattened wire.

One embodiment provides an electric rotary machine unit including: a first electric rotary machine having a first stator; and a second electric rotary machine having a second stator. A coil configured by plural coil segments is disposed in each of the first and second stators. The first and second stators are disposed so that connecting portions of the coil segments or joint portions of leg portions of the coil segments are positioned between the stator cores thereof. First and second feeding portions are interposed between the first and second stators in the axial direction and spaced apart from each other in the circumferential direction.

An actuator for moving a first component relative to a second component includes a first actuating mechanism secured to the first component and having a first motor, a first nut, and a first shaft secured to the first motor and the first nut such that the first nut is rotatable with the first motor. A second actuating mechanism is secured to the second component and has a second motor, a second nut, and a second shaft secured to the second motor and the second nut such that the second nut is rotatable with the second motor. A screw is threadably engaged with the first nut and the second nut such that rotation of at least one of the first motor and the second motor causes movement between the first and second nuts to move the second component relative to the first component.

Flywheel systems with multiple generator coils are provided with a rotor disk configured to rotate about a rotational axis; a plurality of magnets disposed in the rotor disk, the plurality of magnets angularly distributed around the rotational axis, and the plurality of magnets magnetically aligned such that respective magnetic north poles of each magnet of the plurality of magnets face a same direction; and a coil disposed adjacent to the rotor disk, the coil extending axially away from the rotor disk, and the coil positioned to sequentially overlap each magnet of the plurality of magnets in response to rotation of the rotor disk about the rotational axis.

Pairs of unidirectionally magnetic rotor/stator assemblies are mounted for synchronous rotation and complementary, so that one creates pulsating positive current flow and the other creates pulsating negative current flow, as the rotor and stator in each assembly are rotated with respect to each other. The pulsating positive current flow and pulsating negative current flow are combined at a desired phase angle to create alternating current, without power loss due to reversal of current flow.

A wind turbine panel is configured to distribute electricity to a load. The wind turbine panel includes a frame further comprising a first slot having a first slot first end and a first slot second end. A first alternator is located in a first alternator mount on the first slot first end. A second alternator is located in a second alternator mount on the first slot second end. A wind turbine is connected to the first alternator and the second alternator via a first alternator shaft and a second alternator shaft, respectively. The first alternator and the second alternator are electrically coupled to an electrical outlet point on the frame. Wind traveling through the frame rotates the wind turbine, impels the alternator shafts to generate electricity which is then transferred to an electrical outlet point and further to an electrical panel for use in a plurality of downstream applications.

An electrical machine includes a stator containing bearing plates and windings conducting electrical current and the rotor. The stator has windings conducting electric current embedded in a composite material and shaped into winding segments forming a ring segment of an angular span constituting a part of the full angle. The segments are inserted between the external and internal discs of the rotor. The magnetic poles are embedded and magnetised towards the axial direction of internal discs. The poles are separated from each other with a spacing made of a non-magnetic composite material of the internal and external discs structure. Each external and internal disc has an external reinforcing ring, made of a non-magnetic composite material reinforced with fibres of strength exceeding 1 GPa, formed by winding the fibres together with resin on the cylindrical surface of the discs. The external discs have a ring closing the magnetic circuit.

A gimbal and a method for winding a flexible cable on a gimbal are provided. The gimbal includes a first motor and a second motor connected with each other. The flexible cable includes a connection unit and a connection end connected with each other, and the connection end is extended from the connection unit. The gimbal winding method includes winding the connection unit on the first motor while allowing the connection end to be electrically connected with the second motor.
