T.a.i.m.

The Tubular Axle Induction Motor was developed by R&DD in conjunction with GEC, in the late 70's and early 1980's.

The idea was based upon an 'inside out' induction motor with a wound stator inside an APT-E type tubular steel axle.

It appears that it depended upon extreme and virtually unobtainable engineering tolerances in the environment in which it was working. The idea was eventually abandoned.

Here is an internal R & D document about T.a.i.m. with a picture and diagram.

As part of the project a half-scale model was constructed by BR graduate engineering management trainees as part of their attendance at Loughborough University. I am indebted to John Lindsay for the following photographs

	A close up of the sectioned bearings on the model
	The model was completely sectioned to show its construction and operation.
