Development of Axial Flux Permanent Motors with Amorphous Cores

摘要

In electrical machines, the use of rare-earth magnets enables smaller motors to perform with higher power and efficiency. Over the past 30 years, electrical machines equipped with rare earth magnets have been used in a wide variety of industries such as automotives, home appliances, electronics, and power plants. With increasing demand for green energy products, rare earth magnets have become virtually indispensable in the industrial market. However, the limited supply of rare earth elements such as neodymium and dysprosium has made the development of alternative technologies for high efficiency motors a top priority. This research aims at increasing motor efficiency without relying on rare earth metals by using a novel motor design to decrease losses within the motor.
