Periodic Maintenance/ Insulation History The only accurate way to evaluate the condition of the winding insulation is to maintain a history of the insulation readings.
U.S. ELECTRICAL MOTORS INSTALLATION AND MAINTENANCE ( C ) Insulation resistance readings must not drop below the value indicated by the following formula: Rm = Kv + 1 Rm = minimum insulation, in megoh.
U.S. ELECTRICAL MOTORS INSTALLATION AND MAINTENANCE IV. INSTALLATION LOCATION When selecting a location for the motor and driven unit, keep the following items in mind: 1. The location should be clean, dry, well ventilated, properly drained, and provide accessibility for inspection, lubrication, and maintenance.
