Telechron Rotors by Sequential Numbers Listing of Telechron Rotors by their "M" # All Telechron rotors are no longer in production from ANY source. I have many rotors rebuilt and in stock. Any rotor that is not in my stock I can rebuild even the aluminum ones. Any rebuilt Telechron "B" rotor can have any shaft you'd need. Once I open up a "B" rotor I can install any configuration of shaft or pinion. The Telechron rotors that I sell at: http://www.atmosman.com/rotor.html , are the copper and nickel rather than the aluminum that were made from the early 1970's. I don't list or sell any 50 cycle rotors. There is a great book on the subject of Telechron/G.E. clock and it's called, "Electrifying Time" by Jim Linz. Please be aware that the procedure described in the book as "New Life into Dead Rotors" is flawed. The reason is that he suggests using lacquer thinner. Lacquer thinner will slowly destroy phenolic wheels, which are employed in all Telechron rotors. The Telechron "B" rotor was in production as early as 1919 and, the "B-3" has the greatest torque followed by the "B-2". The "M" number of the rotor was Telechron's way of identifying the customer and not the rotor. It has some significance in "B" rotors but all 3.6 rpm "H's" have the same torque.

Information on the Rotor The type of rotor (B-3, B-2, H-3, etc.), TOP (This is significant because all rotors are self lubricating and the word TOP must point straight up for the self lubrication to be its most efficient.) The "M" # (M-1, M-31, M-38 etc.) The RPM's of the rotor (RPM), The current in cycles (CY), A production number Return to IndexCoil & Plate Information Information on Telechron coils is intended as a user guide because many past repair people just grabbed any coil that they could get there hands on and for longer life of the clock and rotor, you should seriously consider replacing the coil if your is not the proper wattage. If your clock is "humming" and the rotor is not at fault, then your coil could be oversized for the field. Meaning that if your coil was replaced with an oversized coil, then that will produced a hum which some cannot diagnose. The "plate" over the back of the rotor has all the information you need. This plate cover contains the following information:
All coils cost $150.00 plus the $20.00 shipping (Canada is $45.00), if that is all you order,
otherwise the same shipping package can be used if you order the
motor/rotor at the same time, so no additional shipping costs are
necessary.

Copyright © 1998-2023 by Michael P. Murray & Mike's Clock ClinicI, Mike Murray, make no claims as to the accuracy or completeness for the Telechron rotor information. But I have made every effort to make sure that the information is accurate. I was given this information many years ago and have continually updated for accuracy and completeness.
