Matt,
The only mechanism I can imagine that would load down the motor would be if
the electrodes somehow welded themselves together and stopped the rotor!
The main factor that would slow down an asynchronous motor would be the
dropping of mains voltage under the load of the power transformer supplying
power to the coil.  If the mains is sufficiently "unstiff", it could also
cause a synchronous motor to drop out of sync.

Rotor load is related to rpm, I think it goes up as the cube of rpm due to
frictional and turbulence effects of the air.
