How to maintain and service permanent magnet direct drive motors?

2024-07-16

The importance of permanent magnet direct drive motor maintenance and care is to ensure the stable and efficient operation of the motor and extend its service life. Through regular cleaning, inspection, lubrication, and testing, potential problems can be discovered and solved in time to prevent failures. At the same time, proper maintenance and care can also optimize motor performance, improve operating efficiency, and reduce energy consumption and maintenance costs. Therefore, it is very important to carry out scientific and standardized maintenance and care of permanent magnet direct drive motors. The following are some key steps and precautions:

01 Cleaning and Dust Removal

Regularly clean the permanent magnet direct drive motor to remove dust, sludge, and other debris. Use a soft brush and a clean rag to clean, and avoid using electrical appliances such as hair dryers that may generate more dust. If the operating environment is dusty, it is recommended to clean it every day.

02 Inspection and Tightening

Frequently check whether the motor terminals and screws are loose or burned to ensure that the connection is firm. At the same time, check whether the displacement is within the specified range. If it exceeds the range, it should be adjusted in time.

03 Lubrication and Oil Change

The permanent magnet direct drive motor operation requires lubrication, and oil should be added regularly to ensure the normal operation of the motor. When refueling, choose the appropriate lubricant and avoid overdoing it. For bearings, they should be cleaned with kerosene and replaced with new oil regularly, generally once every six months, and the amount of oil should account for 1/2~1/3 of the oil chamber when changing the oil.

04 Insulation and Electrical Performance Test

Measure the insulation resistance of the motor regularly, especially in a humid environment. The insulation capacity of the insulating material varies depending on the degree of dryness, so it is very important to keep the motor winding dry. At the same time, the electrical performance test and load test of the motor is carried out regularly to check whether the motor is operating normally.

05 Recording and monitoring

Record the entire process from operation to maintenance, including the operator, usage time, motor temperature, voltage and current, and other parameters, as well as inspection and cleaning conditions. This helps to better understand the use of the motor and detect abnormal conditions in time.

06 Avoid harsh environments

Try to avoid permanent magnet direct drive motors working in humid or high-temperature environments to reduce the possibility of motor damage.

In summary, the maintenance and care of permanent magnet direct drive motors require comprehensive consideration of cleaning, inspection, lubrication, insulation, recording, and avoiding harsh environments. By regularly performing these steps and precautions, long-term stable operation and good performance of the motor can be ensured.
