Synchronous torque motor CWFL series

3-phase48 Vpermanent magnet

Overview
The CWFL13226-35030NW48-S000 is the largest model in the CWFL series — a φ132 mm frameless torque motor kit delivering 3.50 N·m rated torque and 10.50 N·m peak torque at 3000 RPM on 48 VDC. The 16-pole 3-phase PMSM design provides very high torque output for demanding direct-drive applications including industrial robot base joints, heavy-duty rotary tables, and large underwater thrusters.

Key Highlights

• φ132 mm stator OD — largest in the CWFL series for maximum torque
• 3.50 N·m rated / 10.50 N·m peak torque at 3000 RPM on 48 VDC
• 16-pole 3-phase PMSM with sinusoidal back-EMF for smooth FOC control
• Class F insulation (155 °C); optional Hall sensor + temperature sensor
• Custom stator stack, bore ID, and winding — no MOQ
