Description
The Frameless Torque Motor FL-50-08 Equipped with Hall Sensor is a high-performance inner rotor torque motor designed for robotic arms, automation systems, and precision motion control. It features a large center hole, high torque density, smooth rotation, and excellent thermal stability, making it ideal for compact robotic joints and servo mechanisms.
This frameless motor adopts arc-shaped surface-mounted magnets with an eccentric air gap design, reducing cogging torque and ensuring smooth, stable motion. Its sinusoidal back EMF simplifies servo control while delivering excellent dynamic response and precision. The vacuum potting process enhances insulation and vibration resistance, extending motor lifespan even under harsh conditions.
With high-temperature-resistant neodymium magnets, professional Hall element integration, and adjustable lamination thickness, the FL-50-08 motor provides exceptional flexibility for custom robotic applications requiring compact, lightweight, and high-efficiency actuation.
