SFI Series 110W 24VDC Frameless Torque Motor 0.102Nm 38mm Frame Diameter

This SFI Series frameless inner-rotor torque motor features a 24VDC voltage, 110W rated power, 8725RPM rated speed and 0.102Nm rated torque. With a frameless inner-rotor design and no traditional housing, shaft, bearings, or end covers, the motor can be directly integrated into mechanical structures for a more compact and lightweight system. Designed for high acceleration, frequent start-stop operation, and space-constrained applications, it is ideal for robots, aerospace equipment, precision machinery, medical devices, and other high-end automation systems.
