About this product

Leadshine FM1-08523 is a frameless motor component in the FM1 85-class family for integration into robot joints and other compact motion mechanisms. The manufacturer supplies the motor geometry and electrical ratings separately from the drive and joint assembly. Its current catalog gives 2.51 N·m rated torque at 3500 rpm with a 48 VDC rated supply. Current manufacturer tables disagree on selected torque constants, electrical or dimensional values; Specifications preserve the applicable source context rather than reconciling incompatible claims. Cover image: Manufacturer series image; size may vary.
