Axial Electric Motor Design

The rotor construction of a lynch motor a type of axial brushed dc motor.

Axial electric motor design.

The brushes and connections are seen in the centre the alternating permanent magnets not shown align with the segments of the rotor in which current is flowing. In practice the center of the axial gap motor is typically hollow allowing for hollow shaft designs. Many configurations are possible depending on the design goals. While the vast majority of electric motors currently in circulation are radial flux designs magnax claims the key to the high power density it s achieving is the direct drive axial flux design.

Description avid s evo axial flux electric motor is ideal for electric vehicle propulsion and other high performance drive and actuation applications such as robotics actuators and propulsion systems for electrified aircraft. At the right the concentrated windings of the magnax axial flux motor. His brushed dc motor design held the magnets stationary with a spinning armature activated by sliding brushes as the rotor. The technology is scalable from small motors i e electric vehicles to large generators i e wind turbine generators.

Avid technology has prepared this in depth look at electric motor technology used in applications from electric vehicles to robotics and aerospace. Axial flux motors are a major improvement over standard radial flux motors which leave a significant amount of copper overhanging on the ends of the coils. Embedded magnets support high. Cooling in case of radial flux machines the heat has to be transported through the stator to the outside of the machine.

The motors have zero overhang. Lightweight compact and relatively powerful the motor was ideal for electric motorcycles. The coil overhang in a traditional radial flux motor is not beneficial for its functioning left. Axial motors are typically shorter and wider than an equivalent radial motor.

His brushed dc motor design held the magnets stationary with a spinning armature activated by sliding brushes as the rotor. In radial flux motors any copper not. Furthermore thanks to the axial flux design very little copper is wasted on overhanging loops on the windings. That is 100 of the windings are active.
