Synchronous torque motor CWFL10441-40030NW48-S000

three-phase48 Vpermanent magnet

Product Overview
The CWFL10441-40030NW48-S000 is a φ104 mm B-series frameless torque motor kit delivering 4.00 N·m rated torque and 12.00 N·m peak torque at 3000 RPM on 48 VDC. The 10-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

• φ104 mm stator OD, 41 mm stack (B-series) for very high torque output
• 4.00 N·m rated / 12.00 N·m peak torque at 3000 RPM on 48 VDC
• 10-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
