Control of an Axial Flux Permanent Magnet Machine for very wide Constant Power Speed Range
Nowadays, there is an increase in electric power consumption within the vehicles, which is predicted to soon exceed the generation capabilities of the traditional Lundell (claw-pole) alternator. Therefore, Research is focusing on other electric machines topologies, able to provide constant power ove...

| Sumario: | Nowadays, there is an increase in electric power consumption within the vehicles, which is predicted to soon exceed the generation capabilities of the traditional Lundell (claw-pole) alternator. Therefore, Research is focusing on other electric machines topologies, able to provide constant power over a wide range of engine speed, work both as a starter and an alternator and maintain a high efficiency, while not exceeding space limitations. The present thesis reports on the Axial Flux Permanent Magnet Machine with a Novel Mechanical Flux Weakening technique. The principle of operation is explained and a closed loop control for the flux weakening regulation is proposed. As a result, it is demonstrated through simulations that 10:1 constant power speed range can be attained, and possibly extended. |
