Brushless torque motor CWFL07613-08530NW48-S000

synchronous3-phase48 V

Overview
The CWFL07613-08530NW48-S000 is a φ76 mm A-series frameless torque motor kit featuring a 13 mm slim stator stack and a wide 38 mm bore ID. The large central aperture enables routing of cable bundles, pneumatic lines or optical fibres through the rotation axis without increasing outer diameter. The 16-pole 3-phase PMSM delivers 0.85 N·m rated and 2.55 N·m peak torque at 3000 RPM on 48 VDC, providing ultra-smooth low-speed torque for collaborative robot wrists, hollow-shaft rotary tables and compact medical gantries.

Key highlights

• φ76 mm stator OD with 13 mm slim stack (A-series) for axially constrained assemblies
• 0.85 N·m rated / 2.55 N·m peak torque @ 3000 RPM on 48 VDC
• 16-pole 3-phase PMSM for smooth low-speed performance
• Class F insulation (155 °C); optional Hall and temperature sensors
• Customisable stator stack, bore ID and winding with no minimum order quantity
