Synchronous torque motor CWFL05215-04030NW48-S000

brushless3-phase48 V

Overview
The CWFL05215-04030NW48-S000 is a φ52 mm frameless torque motor kit with a 15 mm stator stack, delivering 0.40 N·m rated torque and 1.20 N·m peak torque at 3000 RPM on 48 VDC. The 16-pole 3-phase PMSM topology provides exceptionally smooth low-speed torque, suitable for precision rotary tables, medical imaging gantries, and semiconductor wafer handling.

KEY HIGHLIGHTS
