[LB032381], Letter from Charles Batchelor to Edison Machine Works, September 23rd, 1889

Editor's Notes

"The thousand ampere machine that you have sent us I am very much disappointed with. I was under the impression that this machine would give 1,000 amperes at 10 volts at a reasonable speed, but I find that it is dangerously hot, and will only give 2 ½ volts. This is no good for us, and I would like to know whether you could not take the wire from this armature and twist it similarly to what you do on the heavy current machines of our own types, so as to do away with the enormous foucault currents generated in the wire. Please let me know immediately about this." Yours very truly, Chas. Batchelor.
