Note of the motor long time out

For a long time (three months) out of the Brushed Dc motor, use the insulation resistance should be measured before. Measured with 500V megger motor winding and winding, winding and insulation resistance and shell, if the resistance is lower than 0.5MΩ, they should get rid of the water before turning wet, dry concrete external drying method, drying method and the current both joint drying.

External drying: the use of external heat source for drying, commonly used measures are:

(1) blowing hot air: use install heater blower (hair dryer available agricultural small electric motors for blowing hot air in order to achieve the purpose of drying;

(2) bulb baking: in a closed box, the use of several 200-watt light bulb for about baking, can be baked in the surrounding, but also the agricultural motor apart, place the lamp in the stator hole for baking. Baking heat can be applied thermal infrared lamps or infrared control. Special Note: The baking temperature is not overheating, should be controlled at 125 ℃ or less. Current drying: the impedance of the motor according to farm size and power of the motor phase windings in series or parallel (single-phase motors can be of agricultural primary and secondary windings of the Electric Motor properly connected), then access a variable resistor to adjust the current to rated current value of about 60% power to dry.
