T.a.i.m.
The Tubular Axle Induction
Motor (Taim) 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 generated a great deal of heat in operation and dispersion and cooling proved to be very difficult. Also 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 bogie equipped with two TAIMs was fitted to 920001, a three car unit made up from the remains of PEP stock and comprising RDB 975430, 975431 and 975432. |

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 |
Any more information or pictures of Taim would be gratefully received
