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.

What is axial flux permanent magnet generator?

In this study, axial flux coreless permanent magnet synchronous generator (PMSG) is designed as double stators and three rotors and its electromagnetic and structural characteristics are analyzed. Furthermore, this PMSG does not need a gear system due to its design structure.

What is axial magnetic 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 …

Are axial flux motors better?

Produce lots of torque. An axial flux motor also has a higher power density, developing 30-40% more torque than a similar-sized radial motor, and has better cooling.

Are axial flux motors AC or DC?

Axial flux motors were studied by British inventor and EV enthusiast Cedric Lynch as early as 1979. His brushed DC motor design held the magnets stationary with a spinning armature activated by sliding brushes as the rotor. Lightweight, compact, and relatively powerful, the motor was ideal for electric motorcycles.

Is an axial flux motor AC or DC?

Answer: axial flux motors are AC machines.

How efficient are axial flux motors?

Axial flux motors can also be highly efficient, with efficiencies typically over 96%. That comes from the shorter, one-dimensional flux path, which is comparable to or better than the very best 2D radial flux motors on the market.

What is axial 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. The other type of magnetic flux in an alternator is called RADIAL FLUX and it occurs when the flux occurs “around” the magnet.

What is axial flux motor?

The axial flux motors have flux that runs parallel to the output shaft – along the axis of the shaft, thus, “axial”. A radial flux motor has it’s flux running in and out from the center of the shaft – on the radius – thus, “radial”.

What is an axial flux alternator?

The axial flux alternator (sometimes called a generator), is the heart to many diy wind turbine projects. While a small permanent magnet, D.C. motor, such as the Ametek 30, makes for a very quick and simple project assembly, these motors are becoming very difficult to find and quite expensive.

How does a permanent magnetic generator work?

In a permanent magnet generator, the magnetic field of the rotor is produced by permanent magnets. Other types of generator use electromagnets to produce a magnetic field in a rotor winding. The direct current in the rotor field winding is fed through a slip-ring assembly or provided by a brushless exciter on the same shaft.
