A generator comprises as a first part a stack of disc-like annular rotors 11 spaced one from the other and coaxially located upon and rotating with an elongate central member 15,28 each rotor having an inner annular portion and an outer annular portion, the outer annular portion bearing and/or comprising a magnetic annulus, one or more spacers 19,20,21 being coaxially mounted around the central member in between the inner annular portions of each rotor and abutting against them in such manner such as to brace them to remain orthogonal to the longitudinal axis of the assembly as well as providing the required spacing there between, and as a second part, a stack of annular stators 16 interposed between the rotors and mounted over the spacers but having an inner clearance diameter greater than that of the outer diameter of the spacers. The spacers may be recessed so that the stator may be enlarged to strengthen it and the magnets may radially abut the spacer. The central member may be a shaft 15 or alternatively a weight saving tube 28 |
