50mm DC48V Direct Drive Servo Motorized Roller for High-Speed Cross-Belt Sorters | China Suppliers Factory
High-Precision Direct Drive & Feedback System
Our 50mm Servo Motorized Roller features an integrated external rotor permanent magnet brushless motor. By removing mechanical gearboxes, we’ve achieved a streamlined design that minimizes energy loss and maintenance. The standout feature is the inductive encoder (comprising a rotating module and a fixed stator). Unlike traditional Hall sensors, this high-precision chip provides ultra-accurate feedback, allowing the motor control system to monitor power density and manage start-stop cycles with extreme stability.
Engineered for Harsh Industrial Environments
Logistics hubs can be demanding. Our servo rollers are built to withstand the elements. The inductive position encoding utilizes a non-contact induction principle, making it immune to performance degradation caused by dust, moisture, or mud. This ensures 24/7 reliability for cross-belt sorting machines and induction platforms.
