## What is axial flux technology?

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 …

## How does an axial flux motor work?

Axial flux electric motors feature magnets that are positioned in planes parallel to the coils, allowing them to generate magnetic flux across a smaller rotational volume, resulting in a decrease in the moment of inertia and overall mass of the rotor.

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?

Answer: axial flux motors are AC machines. Acc. powerelectronics..com: “… Figure 3 shows a Magnax 275-mm AFPM motor.

### 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.

How does an axial flux generator work?

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.

#### Who invented the axial flux motor?

It can be divided into two types: axial flux motor and radial flux motor, according to the direction of the magnetic field. The world’s first motor, invented by Michael Faraday in 1821, belongs to the axial flux type.

#### What is the difference between axial flux and radial flux?

The difference as their names imply is that in axial flux the magnetic flux direction is parallel to the machine rotation axis whereas in radial flux machines, the magnetic flux direction is radial.

Electrical machines can be classified into two categories – radial and axial flux machines. The difference as their names imply is that in axial flux the magnetic flux direction is parallel to the machine rotation axis whereas in radial flux machines, the magnetic flux direction is radial.

## How do axial compressors work?

An axial-flow compressor compresses its working fluid by first accelerating the fluid and then diffusing it to obtain a pressure increase. The fluid is accelerated by a row of rotating airfoils or blades (the rotor) and diffused by a row of stationary blades (the stator).

What is axial flux motor?

Axial flux technology There are two principal topologies of axial flux motor – dual-rotor singlestator, sometimes called torus-style machines, and single-rotor dual-stator. Most permanent magnet motors these days work with a radial flux topology.

### What is a dual-rotor axial flux machine?

In a dual-rotor axial flux topology, the flux loop starts at the first magnet, passes axially through a stator tooth, and immediately arrives at the second magnet. That means the flux path is much shorter compared to that in radial flux machines, allowing the motor to be smaller for the same power, and have a higher power density and efficiency.

### What is radial flux distribution in an electric motor?

Typically the electric motors are designed and constructed in order to use the radial flux distribution, of an axial where rotor and stator have a small radial air gap between them – Figure 1.

What is the difference between axial-flux and radial motors?

This aspect of axial-flux motor design typically delivers a 30% torque density advantage over a conventional radial motor. However, the YASA motor topology also removes the stator yoke, which reduces the stator iron mass by up to 80%.
