Solar tracker actuator drive connector

The customer makes compact actuators for solar tracking systems. A POM connector transmits force between the motor reduction assembly and the adjustment mechanism under repeated mechanical loads.

Standard POM showed no obvious issue in short-term operation, but simulated long-term loading made the connection hole slightly oval and progressively increased mechanism clearance. The customer wanted more stiffness while retaining low weight and injection-molding production.

Taiyi Polymer recommended EGH502T POM with 25% glass fiber.

Ribs around the connection hole were revised to distribute load over a larger structural area instead of relying only on a thicker hole wall.

The customer reported improved hole-shape retention after repeated loading and a slower increase in mechanism clearance. More samples were then prepared for complete-system life validation.
