Brushless torque motor CWFL08834-26030NW48-S000

synchronous3-phase48 V

Product Overview
The CWFL08834-26030NW48-S000 is a φ88 mm B-series frameless torque motor kit delivering 2.60 N·m rated torque and 7.80 N·m peak torque at 3000 RPM on 48 VDC. The 10-pole 3-phase PMSM design provides high torque output for direct-drive applications such as industrial robot base joints, heavy-duty rotary tables, and large-format gimbal systems.

Key Highlights

• φ88 mm stator OD, 34 mm stack (B-series) for high torque output
• 2.60 N·m rated / 7.80 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 minimum order
