Default Re: Vintage 1/4 horsepower induction motor

Today I attached a temporary mains lead to the carbon brush holders and cautiously powered the motor up from a Variac. Works a treat! The centrifugal starting switch operates correctly and the rotor spins up freely, albeit a tad noisily but it probably needs to be stripped down and serviced properly. No-load running current is around 2.25 amperes at 220 volts.

I attach some pictures which I hope will aid identification. The terminal block is damaged and the electrical wiring is purely for test purposes.
