Asymmetrical Reluctance Machine
- 總結
- Researchers at Purdue University have developed a reluctance machine with an asymmetrical rotor pattern called asymmetrical reluctance machine (ARM). This new design has been optimized to improve the torque density significantly in one direction by sacrificing torque density in the reverse. As opposed to some symmetrical designs, such as the induction motor (IM) and permanent magnet synchronous motor (PMSM), the ARM can produce the same high torque densities without significant safety and cost concerns. Low manufacturing costs can be achieved because rare earth magnets are not needed. This development can prove to be useful in many applications, including the household appliances, automotive, and electronics industries.

- *Background
- Reluctance motors are a type of electric machine that induce a magnetic field on a ferromagnetic rotor in order to generate torque. Such motors have a simple design and low manufacturing costs and are easy to control. Currently, the rotors of a typical reluctance machine are designed to utilize their symmetrical shape; however, they cannot produce sufficient torque density necessary for some applications.
