| 86134 By/RD. From Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.4/MA.20.11.33. NEW 4.75" BENTLEY MOTOR. With the use of a thicker carcase on the Bentley starter motor we gain about 8 lb inches extra torque with a current of 300 amperes which represents an increase of approx. 6½%. This rather suggests, after consideration, that a slightly thicker carcase would be an advantage. Other improvements would be a longer brush to reduce contact drop and brush losses, and possibly "Lohys" poles. Hs{Lord Ernest Hives - Chair}/Wst. | ||
