What is an axial flux electric motor?
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 axial flux technology?
An axial flux motor places the permanent magnets on the face of the rotor, and puts the stator in front of the rotor. To balance the magnetic forces, two rotors are often used—one on either side of the stator. The flux loop starts at a magnet on the rotor and passes through the air gap between rotor and stator.
Are axial flux motors better?
In a radial flux motor, magnetic flux moves from one tooth to the stator, back to the next tooth, and then to the magnets. On the other hand, an axial flux motor has a more efficient magnetic flux path: from one magnet, through the core, to another magnet.
What is flux in motor?
Flux: The flow of current through a conductor creates a magnetic field. Flux defines the rate of flow of a property per unit area. Flux current is the rate of current flow through a given conductor cross-sectional area.
What is difference between radial and axial?
Two examples are axial loads, or thrust loads, and radial loads. Axial bearings, or thrust bearings, are designed to withstand force in the same direction as the shaft. Radial ball bearings are designed to withstand forces that are perpendicular to the direction of the shaft, or radial loads.
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. Bottom Plate Page 6 3 rotor. The alternating magnetic field from the rotor induces a voltage in the coils of the stator.
How does axial flux generator work?
What are the disadvantages of a axial flux motor?
axial flux motor disadvantages Mechanical challenges: Because of the strong magnetic forces operating between the rotor and the stator, keeping a high-tolerance uniform air gap between these two components is a challenging engineering and material problem.
What does radial and axial mean?
What does radial and axial load capacity mean? The radial force is the force acting perpendicular to the shaft axis. The axial force acts in the direction of the axis, meaning along the axis, of a body. Optimally, axial ball bearings absorb large forces that act in the direction of the shaft axis.
What is radial and axial alignment?
Radial (offset or parallel) misalignment. The centrelines of the two shafts are parallel but offset. Axial (or end float) misalignment. The two shafts are aligned but one (or both) axles are prone to in/out movement along the centreline.
