Asynchronous motors are used in many agricultural industries. Agricultural production is a production with high humidity. As noted above, one of the main reasons for the failure of electric motors in agricultural installations during prolonged downtime is the insulation breakdown due to its dampness. Moistening the winding insulation will degrade the dielectric performance of the insulation. If the electric motor is often switched on and the total operating time per day is at least 4 - 6 hours in rooms with high humidity but without ammonia vapors, then dangerous waterlogging of the windings does not occur. Preheating the windings for an electric motor with a power of 3 kW, to maintain the state of the insulation resistance at a level safe for switching on, can be provided with a power of 12 W.
