AI Technical Summary
In high-performance hydraulic servo systems, heat buildup inside the motor can cause electronic components to burn out and motor performance to degrade, and existing technologies struggle to effectively dissipate heat.
Design a flow channel system integrated inside the valve body, including multiple fluid channels, with at least one fluid channel having a heat exchange extension section that is directly thermally coupled to the wall surface of the motor mounting well, using hydraulic oil for active heat dissipation.
It significantly improves motor operating temperature, enhances the reliability and lifespan of servo valves, improves servo valve performance stability, and features a compact structure and high integration.
