As an essential power source in industrial production, the proper storage of electric motors has a direct impact on their service life and performance. Improper storage can easily lead to issues such as insulation moisture, rust, bearing damage, or mechanical deformation. Therefore, before the motor is put into operation, it must be stored and maintained in strict accordance with standard procedures.
The motor should be stored indoors in a dry, well-ventilated area, free from corrosive gases. Avoid direct sunlight or proximity to heat sources to prevent deformation or aging of the motor housing and internal components.
The relative humidity should be kept below 70%.
The ambient temperature should be maintained between 5°C and 40°C.
In humid environments, the motor should be placed on a raised platform to avoid moisture intrusion from the floor.
Vibration and Moisture Protection: Place the motor horizontally and securely on a vibration-absorbing pad or wooden pallet to prevent deformation.
Rust Prevention: Apply anti-rust oil to exposed shafts and cover them with anti-rust paper. For long-term storage, check the anti-rust layer periodically to ensure it remains intact.
Ventilation Space: When multiple motors are stored together, keep adequate spacing between them for air circulation and to prevent mechanical compression or moisture accumulation.
If the motor is stored for more than three months, check whether the bearings are flexible and the rotor can rotate freely.
Every 1–2 months, manually rotate the motor shaft several times to prevent bearing grease aging or corrosion of rolling parts.
Inspect the housing, rust-proof coating, terminal box, and sealing components regularly. If any abnormality is found, take corrective measures immediately.
During handling, avoid impact, tilting, or vibration. The motor should always be lifted from the base, never by the fan cover or lead wires. If the motor has a protective cover, it must remain intact during transportation and storage.
Before operating a motor that has been stored for a long period, conduct a comprehensive inspection:
Check that the insulation resistance is within the safe range;
Verify that the bearings and rotor rotate smoothly;
Ensure the terminal connections are firm and corrosion-free;
Confirm that the exterior is free from rust, moisture, or unusual odors.
Proper storage is the foundation of reliable motor performance. Shandong Fuxing Motor Co., Ltd. provides high-quality three-phase asynchronous motors with excellent efficiency, durability, and stability — ensuring reliable operation for your industrial equipment.
