What is the average lifespan of an electric motor?
1 Answers
The typical lifespan of an electric motor is around 15 years. Under normal conditions, the service life of an electric motor can reach 10 to 20 years; however, if the vehicle operates in sandy areas for extended periods, replacement may be required after 5-6 years. Most engines on the road today are designed with a service life exceeding 200,000-300,000 kilometers, but commercial vehicles with regular maintenance and virtually unlimited budget considerations can surpass 500,000 kilometers. The lifespan of an electric motor is determined by the following factors: The prerequisite is a qualified, standard-compliant motor meeting specifications such as power rating, temperature rise, efficiency, and insulation class. Under these conditions, the influencing factors include: overload, ambient temperature, grid voltage, and installation precision (due to incorrect installation causing radial and axial loads when actual operation requires tangential load). Here are maintenance measures for automotive generators: Monitor bearing wear; if insufficient lubrication is detected, add a few drops of oil through the oil cup opening. If the brush contact surface is uneven, smooth it with fine sandpaper. Replace components when spring elasticity is inadequate or brushes are excessively worn. The generator's dust seal ring should remain securely in place and should not be removed.
