hi im struggling to find how you work out the rpm of an universal motor. ac will do for now as thats 50hz in the uk. i have an universal motor with 2 field windings and 20ish commutator segments on the rotor.
i'd like to know what rpm it would run at 240v 50hz ac and on dc. my guess is 3000rpm ac and 10000+ maybe explode with cenrifugal force or just arc excessively if given no load dc and a high enough voltage. can any one correct me or is that about right?
the motor is 2000w from a karcher jetwash.
thanks
