A New Axial Flux Permanent Magnet Synchronous Machine (»Disc Machine«)
13. februar 2008, Maribor
TECES has developed and produced prototype of Axial Flux Permanent Magnet Synchronous Machine (AFPMSM) with Ironless Stator Core and rated power of 4,5 kW (for more information about these machines click here).
Newly developed AFPMSM prototype has the following advantageous features:
- due to the nonmagnetic stator core can operate at higher efficiency than conventional machines,
- owing to its compact construction and high power density (at rated voltage) is more frequently used in different applications,
- operates without cogging torque and permeance-dependent torque ripple.
Main applications:
- small to medium power generators,
- electromechanical drives for transportation and elevators.
AFPMSMs can be divided into power categories; this prototype AFPMSM can be classified into category of small power AFPMSMs, which are usually designed as a slotless surface mounted permanent magnet machines.
The main purpose of the prototype AFPMSM production was the verification of program package for analytical calculation (calculation of back EMF, torque and magnetic field), developed by TECES particularly for this and related machines types. The verification of the characteristics confirmed a good agreement between the measurements, analytical calculations and results obtained by FEM (Ansys).
The program package for analytical calculation enables faster, more effective and simpler analysis and optimization in comparison to commercial program packages, which are an excellent supplement to analytical methods, especially when considering saturation effects and geometry details in the machine construction.
The production of the new series of multipurpose small prototype AFPMSMs is projected using the verified program package for analytical calculation. The experiences show several important advantages of AFPMSMs in comparison to conventional machines and therefore they can successfully replace them.
