HP contains a RPM value, Torque does not have to necessarily.
For an induction motor, Less poles = lower inductance, The H.S, 2 pole spindles posses very low inductance and the inductive reactance at anything lower than 100Hz gets progressively lower as the frequency decreases, hence the overheating..
