electric motor

[Donnyboat]

A mate gave me an electric motor, but know info of RPM, the only details it has on it, B&G, or maybe the G is a D, it also has NOT-401-62, in another area it has an, M, I have had it running on 240 volt, single phase, it has a half inch drive shaft, but it dont say how many RPM, and I dont have a rev counter., any info would be handy thanks, Don.
