Abstract
An electric drive motor for an underground mining machine includes a capacitive-type detector supported within the motor housing for contact by fluid that may penetrate beyond the motor shaft seals and the like. The capacitance of the detector decreases when fluids penetrate the motor shaft seals and electrical circuitry detects such a capacitance change of the detector for indicating the presence of fluids within the motor housing to prevent damage to the motor windings. The disclosure includes several forms and arrangements of the detector for the electric motor.
