The working principle of the life test bench is to simulate the actual operating conditions, load mode and service environment that the product may encounter during normal use. By applying continuous or cyclic loading, running continuously and repeatedly, it accelerates the wear, fatigue and aging process of the tested sample. During the test, relevant parameters such as performance changes, damage status and failure time are recorded and monitored in real time, so as to evaluate its service life, durability and reliability.

Testing the Service Life of Carbon Brushes

Test the service life, durability, and long-term reliability of motor carbon brushes under simulated real-world operating conditions. Through continuous and cyclic operation tests, evaluate the product’s fatigue resistance, wear resistance, and resistance to aging, and determine the product’s practical service life limit and failure modes, thereby providing a basis for product design optimization, quality control, and performance verification.
