- TL;DR Summary
- can a permeable but non magnetic rotor be used in an electric motor?
Let's say, the disc has a circumference of 1m, made of steel, or copper if you like.
The stator has a north and a south pole facing the surface of the disc, let's say at the perimeter of the disc, one perpendicular to the left and one perpendicular to the right ie opposite sides of the spinning disc. The offset between north and south at the circumference is 1cm, or perhaps variable - and as close as practical without touching the surface of the disc (or, touching but frictionless perhaps).
What speed at the perimeter, where these poles are placed 1cm rotationally from each other, does the disc need to spin for the inducted field in the disc to peak just as it passes the next stator pole, and give propulsion to the disc?
