brushlesssynchronous48 V

Product summary
The CWFL08813-11030NW48-S000 is a φ88 mm A-series frameless torque motor kit that pairs a slim 13 mm stator stack with a large 41 mm bore ID, allowing cables, coolant lines, or optical paths to pass cleanly through the joint centre. The 16-pole 3-phase PMSM delivers 1.10 N·m rated / 3.30 N·m peak torque at 3000 RPM on 48 VDC with ultra-smooth low-speed torque, suitable for collaborative robot elbow and shoulder joints, hollow-shaft direct-drive rotary tables, and compact medical imaging gantries where axial compactness and central routing are required.

KEY HIGHLIGHTS
