Frequently Asked Questions:
Q. How should I store WorldWide Electric PEWWE15-36-215JP motor?
A.
- Place the motor indoors in a dry area with a consistent temperature above -20 degrees C.
- Ensure the storage area is well-ventilated, free of dust, and devoid of sunlight.
- Elevate the motor off the floor using rubber mats if possible.
- Avoid storing the motor near sources of heat or cold, such as boilers or freezers.
- Store the motor in an upright position.
Q. How often should I check the winding insulation resistance during storage?
A. Measure and record the resistance of the winding insulation every 30 days of storage.
Q. What conditions should the storage area maintain?
A. The storage area should have humidity levels below 60% and should be free of shock or vibration. Vibration should not exceed 2 mils maximum.
Q. Is there anything I should do to ensure the longevity of the bearings?
A. Yes, rotate the shaft of the motor 15 revolutions, stopping at a different position each month. This helps maintain a proper distribution of grease in the bearing cavity.
Q. How should I handle the WorldWide Electric PEWWE15-36-215JP close coupled motor to avoid injury?
A. To avoid injury, use proper material handling equipment. When removing the motor from its packaging, use caution because sharp corners may exist on surfaces such as the motor shaft, motor key and sheet metal.
Q. What precautions should I take before lifting the motor?
A. Before lifting the motor, ensure that all eyebolts are properly tightened and that the shoulders of the motor are in contact with the base.
Q. How to assess the condition of a long-stored or exposed WorldWide Electric motor?
A. To ensure the motor's integrity, it is advisable to check the insulation resistance of the stator windings using a megohmmeter.
Q. What should I do if the insulation resistance is lower than 1 megohm?
A.
If the resistance is below 1 megohm, the windings should be dried using one of the following methods:
- Bake in an oven at a temperature below 194 degrees F (90 degrees C) until the insulation resistance stabilises for at least 30 minutes. Continuously monitor the conditions during the baking process.
- With the rotor locked, apply a low voltage (approximately 10% of the motor's nameplate voltage) and gradually increase the current through the windings until the temperature, measured with a thermometer, reaches 87 degrees C (188 degrees F). It is crucial not to exceed this temperature. Maintain this temperature until the insulation resistance remains constant for a minimum of 30 minutes.
