[0002] In modern industrial production, multi-motor coaxial drive systems are widely used in various fields such as mining, metallurgy, chemical industry, and papermaking. This drive method can provide greater power output to meet the operating requirements of heavy equipment. However, multi-motor coaxial drive systems also face the problem of power balance. Due to factors such as differences in the characteristics of each motor, load changes, and nonlinearity of the transmission system, it is often difficult to maintain consistent output power between different motors. Power imbalance can lead to problems such as motor overload, uneven heating, and shortened lifespan, seriously affecting the reliability and stability of the system. To solve the problem of multi-motor coaxial power balance, researchers have proposed various control strategies, such as master-slave control, cross-coupling control, and fuzzy control. These control strategies need to be verified and optimized using actual test equipment.
