A general statement about service life cannot be made due to many influencing factors. We must consider the following factors:
1. Electrical loading: high current will speed up the electrical wear of the motor. Therefore, it is recommended to
select a motor with a broader Margin. We would be happy to provide some suggestions for your reference.
2. Speed: the higher the speed, the greater the mechanical wear.
3. Type of operation: extreme start/stop, repeatedly clockwise and anti-clockwise rotation will reduce service life.
4. Environmental factors: temperature, humidity, vibration and type of installation etc.
