Problem Diagnosis:

First of all, I carried out a visual inspection according to the operation manual and did not find any obvious damage or blockage by foreign objects. Then, I used measuring tools to check the voltage and current of the motor and found that the current was slightly unstable. Therefore, I decided to disassemble the motor for further inspection.

Detailed Description of the Maintenance Process:

Power-off and Safety Measures:

At the beginning, I ensured that the motor and related equipment were completely powered off. To ensure safety, I put on insulating gloves and goggles, and at the same time, I set up warning signs near the motor to prevent anyone from accidentally touching or turning on the power supply. After cutting off the power, I used a voltage tester to check and make sure there was no residual voltage, thus ensuring my safety and the safety of the maintenance process.

Disassembling the Motor:

Then, referring to the operation manual of the YE2 high-efficiency energy-saving motor from Simo, I started to disassemble the motor. First, I used appropriate tools to slowly loosen and remove the fixing screws of the casing. When removing the fan cover and the fan, I was particularly careful to prevent any part from being damaged. To facilitate the subsequent reassembly, I marked each disassembled part and placed them in order to ensure that each step could be reversed.

Inspecting the Bearings and the Rotor:

After disassembling the motor, I first inspected the rotor and confirmed that there was no obvious physical damage or deformation. Subsequently, my attention turned to the bearings. By carefully observing and rotating the bearings to check their smooth running, I found that the bearings had slight sticking and uneven rotation, which were obvious signs of bearing wear. This wear was very likely the cause of the decrease in the motor's efficiency.

Replacing the Bearings:

After determining that the bearings needed to be replaced, I ordered new bearings according to the model and requirements of the YE2 motor. After receiving the new bearings, I first ensured that they were exactly the same as the original bearings in specifications. Before replacing the bearings, I cleaned the bearing seats and related parts with a cleaner, and then gently installed the new bearings in place. Throughout the process, I ensured that special tools were used to avoid damaging the bearings or the motor.

Cleaning and Lubrication:

After replacing the bearings, I thoroughly cleaned the inside of the motor, especially the rotor and stator parts, using a dust-free cloth and a special cleaner. After cleaning, I checked whether the internal cables and connections were firm and undamaged. After completing these tasks, I lubricated the new bearings, using the lubricating oil recommended for such high-efficiency motors to ensure the good performance and service life of the bearings during operation. During the lubrication process, I ensured that the lubricating oil was evenly distributed and avoided excessive lubrication, because excessive lubricating oil would lead to accumulation and overheating problems.

Throughout the maintenance process, I operated strictly in accordance with the manufacturer's instructions and industry best practices to ensure that the performance of the motor could be fully restored. This maintenance also reminded us of the importance of regular maintenance. Through this meticulous maintenance and repair, the YE2 high-efficiency energy-saving motor from Simo has restored its excellent performance and once again serves our production line efficiently.

This maintenance and repair process reminds us that even high-efficiency energy-saving motors need regular inspection and maintenance. By replacing the worn bearings in a timely manner and carrying out thorough internal cleaning and lubrication, we have successfully restored the efficient operation of the motor. This not only ensures the stable operation of the equipment but also extends the service life of the motor. As a maintenance personnel, I believe that regular inspection and maintenance are the keys to ensuring the long-term and efficient operation of the motor.
