What is an axial flux alternator?
A permanent magnet alternator generates power by passing magnets past a group of coils of wire. The magnetic field that surrounds a magnet is call it’s flux. Axial Flux simply means the lines of magnetic flux that past through the coils of wire, travel along the “axis” of the turning motion.
What is meant by axial flux?
An axial flux motor (also known as an axial gap motor, or pancake motor) is a geometry of electric motor construction where the gap between the rotor and stator, and therefore the direction of magnetic flux between the two, is aligned parallel with the axis of rotation, rather than radially as with the concentric …
What is an axial flux generator?
In an axial flux generator, also known as a pancake generator, the rotor is a flat disk of magnets which rotates on a shaft above a flat ring of stator coils.
Is axial flux an AC motor?
The magnets on the rotor of an axial flux motor, like all forms of AC synchronous electric motors, are attracted to the spinning field generated by a surrounding ring of independent electromagnets in the stator.
Who manufactures axial flux motors?
YASA’s axial-flux design has efficiency at its core, offering efficiencies greater than 96% and an innovation roadmap to even greater efficiencies.
What are axial flux motors used for?
Axial flux motor is ideal for high torque density and space-constrained applications. Most people assume that high power density is only determined by fast speed, and they ignore the impact of torque density.
What is dual rotor axial flux generator (drafg)?
Dual Rotor Axial Flux Generator (DRAFG) is a permanent magnet axial flux generator commonly used for low-speed power generation using wind power. This generator can generate useful amount of voltage even under very low revolutions per minute (RPM).
What are the characteristics of wind and water turbine alternators?
Main characteristics of wind and water turbines alternators Rated power from 200 W up to 95 kW depending on size and rated speeds. Rated speeds from 80 RPM up to 1500 RPM. Six overall diameters from 145 mm up to 795 mm. Internal diameter from 56 mm up to 630 mm. Various available voltages up to 500 Vac.
What type of stator do I need for axial flux?
Most axial flux wind turbines use a three phase stator for more efficient generation. Since this is a single rotor design (stators on Otherpower are usually made for dual rotors) we will only be generating half the stated voltage. So, for this project I wanted 12 volts and had to buy a 24 volt stator.
What is an axial flux magnet?
The axial flux (disc shape) permanent magnet machine is an attractive alternative to radial flux (cylindrical shape) machines in wind turbine applications. The axial flux configuration is amenable to the low-speed, high-torque operation of a direct drive wind energy system.
