DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} From Hs{Lord Ernest Hives - Chair}/Wst. c. to Hn.{F. C. Honeyman - Retail orders} c. to E.{Mr Elliott - Chief Engineer} x6115 Hs{Lord Ernest Hives - Chair}/Wst.3/MA.14.3.33. WINDSCREEN WIPERS. As referred to in our Hs{Lord Ernest Hives - Chair}/Wst.1/MA.1.3.33., we have now obtained comparative figures of performance for the Klaxon and Lucas dual wipers, as follows:- (1) Running current under maximum load conditions :- Lucas 1.7 to 2.0 amperes. Klaxon 3.0 to 3.5 amperes. (2) Stalled current :- Lucas 3.8 amperes. Klaxon 8.0 amperes. (3) Temperature rise under maximum load conditions:- Lucas 50°C. Klaxon 95°C. The Klaxon is series wound and thus has a big variation of speed and current with torque and a high stalling current whereas the Lucas is a shunt wound machine. Hs{Lord Ernest Hives - Chair}/Wst. | ||
