PM-free magnetic-modulated dual-axis motor for automotive applications.

What is it about?

Novel PM-free magnetic-modulated dual-axis motor is proposed in this paper, and demonstrated its drive performance through the downsized prototype. The unique point of this proposed motor is that it is able to utilize wasted rotating magnetic field for inner-rotor magnetization with self-excited technique.

Why is it important?

We propose novel magnetic-modulated motor without PMs. It can achieve the cost reduction and get the variable magnetic flux function for wide adjustable speed drive characteristics.
