| To Hy.{Tom Haldenby - Plant Engineer} from EFC. X7S- EFC1/T13.6.28. The Expl. Dept. may require in the near future one, or perhaps two, 3-brake-horse-power simple shunt wound D.C. motors for 100/140 volts, together with suitable starter and field and armature regulating resistances for a speed variation over a reasonable range. Would you please send out enquiries and/or obtain suitable quotations for such apparatus. EFC. | ||
