A deicer for an air gap between the rotor and stator of a rotating machine having a rotor and stator combination includes a heating assembly preferably disposed in the stator adjacent the air gap to heat the air in the air gap. Heating assembly includes an electrically powered resistive heating element wound through armature slots of the stator. The disclosed device and method have principal applications in emergency-type devices like Ram Air Turbines (RAT) and other power conversion devices such as Hydraulic Motor Generators (HMG) and Electric Motor Pumps (EMP).
