portable 3 phase induction heaters
I would love it if someone could educate me in induction heaters.
I work with electric motors/generators, often my job is to change bearings and with large motors that can be an issue due to the couplings or even the bearings themselves being stuck, in those cases we have to heat them up with torches till they expand enough to be removed, and that can be an issue on sites with high fire risks.
So i wanted to know if anyone has experience in removing large motor couplings with an induction heater.
I would love to know if its even possible, or would the heater heat up the rotor itself enough for it to expand too much, and at what kind of power i would have to be looking at in Kw
P.s. the kind of heater im talking about is one with flexible cable that has to be wound around the coupling, also on a side note could it induce strong enough currents in the windings of the stator for it to become a problem?
