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.
Why are axial flux motors better?
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. In a radial flux motor, magnetic flux moves from one tooth to the stator, back to the next tooth, and then to the magnets.
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 are the advantages of axial flux machines over conventional alternators?
In case of Magnax axial flux machines, the cooling is excellent because the windings are directly in contact with the exterior aluminium outside casing. And Aluminium conducts heat very well. As a result, the windings of Magnax axial flux machines stay cool while the resistance of the copper remains low.
How do pancake motors work?
A pancake motor consists of a printed armature (rotor) between two permanent magnet stators. This construction results in an axial air gap, with magnetic flux that also runs axially, along the length of the motor. … The direction of the force is perpendicular to both the magnetic field and the current.
How do you make an electric motor more powerful?
We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.
How do motors work?
Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current. … Electric Motors have an array of applications.
What is a electric motor called?
An electric motor is an electrical machine that converts electrical energy into mechanical energy. … An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.
What is axial flux permanent magnet generator?
Furthermore, axial flux permanent magnet generator with coreless stator is considered as machines having high power density for energy-generating systems . Rotor is used in the both sides of the stator in traditional machines. … Moreover, reducing the number of the rotor discs used, the machine has been made lighter.
Who invented brushless motor?
Advancements in solid state technology in the early 1960s resulted in the invention of the first brushless DC (BLDC) motor in 1962, what T.G. Wilson and P.H. Trickey called a “DC machine with solid state commutation.” The key element of the brushless motor is that it requires no physical commutator, making it the most …
What is the difference between a motor and an engine?
“People use both interchangeably, but the difference is that motors run on electricity and engines run on combustion. The engine converts various forms of fuels into mechanical force, while the motor transforms electrical energy into mechanical energy.”
What is a pancake motor?
Pancake motors or printed armature motors and servodisc motors as they are also known, are employed for various industrial applications wherever rapid stop-start, zero cogging, low inductance, precise electronic motor control, a low thermal time constant or just a slim, axially flat packaging profile is needed.
What is a pancake BLDC motor?
Printed Motor Works offer two distinct brushless pancake DC motor families: the XR Series using an external rotor and the IR Series using an internal rotor. All our compact brushless DC motors can be tailored to meet your exact specification.
What is servo motor and how it works?
A servo motor is an electromechanical device that produces torque and velocity based on the supplied current and voltage. A servo motor works as part of a closed loop system providing torque and velocity as commanded from a servo controller utilizing a feedback device to close the loop.
