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 a coreless generator?
Coreless PMAFG is a generator that is enabled to turn on energy at low speeds. The chosen model was Double Rotor – Single Stator (12 Slots 8 Poles) using Infolytica Magnet software. Finite Element Method (FEM) was employed to analyze the phenomena of the magnetic flux.
How does an axial flux motor work?
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.
What is radial flux generator?
Radial Flux Motor Most Permanent Magnet Motors and Generators, used today, are radial flux machines. We talk about radial flux because in this type of machine, the magnetic field, or flux, runs radially with respect to the direction of the rotor shaft.
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.
What is axial machine?
Abstract: Axial-field electrical machines offer an alternative to the conventional machines. In the axial-field machine, the airgap flux is axial in direction and the active current carrying conductors are radially positioned.
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 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.
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.
What is difference between radial and axial?
Axial is the direction along the long axis of the wood, radial is the direction along a radius of the circular trunk cross-section, and tangential is the direction that is at right angles to the radial direction.
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.
What is radial flux permanent magnet generator?
This research presents methods to reduce cogging torque in dual-stator radial flux permanent magnet generator (DS-RFPMG). It is a radial generator which has two stators located on the inner and outer sides of the rotor. DS-RFPMG has a simple manufacturing, however its design method is complex.
What does a stator do in a generator?
In an electric motor, the stator provides a magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current. In fluid powered devices, the stator guides the flow of fluid to or from the rotating part of the system.
How do you calculate the flux of a DC motor?
EMF equation and Torque equation of a DC machine
- Average emf generated per conductor is given by dΦ/dt (Volts) … eq. …
- Flux cut by one conductor in one revolution = dΦ = PΦ …. (Weber),
- Number of revolutions per second (speed in RPS) = N/60.
- Therefore, time for one revolution = dt = 60/N (Seconds)
- From eq.
What is synchronous motor?
A synchronous motor is one in which the rotor normally rotates at the same speed as the revolving field in the machine. The stator is similar to that of an induction machine consisting of a cylindrical iron frame with windings, usually three-phase, located in slots around the inner periphery.
What is the difference between axial and radial capacitors?
Axial: There are leads coming out either end of the cap. Typically mounted parallel to the board. Radial: Both leads come out of one end. Typically mounted vertical to the board.
What are the advantages of axial flux machines over conventional alternator?
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.
Is a car motor the same as 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 are 3 types of motor controls?
There are four basic motor controller and drive types: AC, DC, servo, and stepper, each having an input power type modified to the desired output function to match with an application.
What is flux with example?
Flux is a chemical purifying agent, flowing agent or cleaning agent. Most commonly, it is used in metal joining and metallurgy. Some examples of flux include: Ammonium chloride. Zinc chloride.
What is saliency ratio?
saliency ratio = Ld / L The d-axis is when the rotor is aligned with the poles. It is also the orientation with highest inductance. The q-axis is when the rotor is aligned with the gaps. It has the lowest inductance. It can be shown that reluctance motors work best when you maximize the saliency ratio.
Are AC or DC motors more powerful?
AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.
What are the 6 parts of an electric motor?

Which motor is best for electric Car?
Brushless DC Motors BLDC motors have traction characteristics like high starting torque, high efficiency around 95-98%, etc. BLDC motors are suitable for high power density design approach. The BLDC motors are the most preferred motors for the electric vehicle application due to its traction characteristics.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
