Abstract

The electrical motor or generator comprises two parts one for transfer and modulation of inductive magnetic flux and the other for creating the indicative flux and carrying the inductive windings. The second part also has inductive North and South poles. The first part may also has inductive windings which may be movable or fixed. The motor can be used as a linear drive with the flux transfer part forming the elongate fixed rail and the flux induction part moving along the latter.
