4 Precautions to Take When Storing an Electric Motor

Proper storage of an electric motor is essential to ensure its longevity and performance when it’s eventually put back into operation. Whether you’re storing a motor for a short period or an extended duration, taking the right precautions can prevent issues such as moisture damage, rust, and electrical failure. Here are four precautions to take when storing an electric motor.
Keep the Motor in a Dry, Temperature-Controlled Environment
Moisture is one of the biggest threats to an electric motor during storage. Exposure to high humidity can lead to corrosion, insulation degradation, and internal damage. It’s important to store the motor in a dry environment with stable temperatures to prevent condensation from forming inside the housing.
Protect Against Dust and Contaminants
Dirt, dust, and other contaminants can accumulate on an idle electric motor and cause problems when it’s put back into use. Over time, debris can enter the ventilation openings, coat the windings, and interfere with the cooling system. To prevent this, cover the motor with a protective wrap or a breathable tarp that shields it from dust while allowing air circulation.
Maintain Proper Electrical Insulation
Over time, insulation materials can absorb moisture, leading to electrical failures when the motor is put back into service. Before storing the motor, ensure that all electrical connections are properly insulated and secured. If the motor will be stored for an extended period, testing the insulation resistance periodically can help detect any degradation before it becomes a serious issue.
Store the Motor in a Stable Position
The way a motor is positioned during storage can impact its long-term condition. It should be stored on a stable, vibration-free surface to prevent unnecessary stress on the housing and internal components. If the motor is large or heavy, it should be securely mounted on a pallet or support structure to prevent damage from movement or accidental tipping.
