Product catalog summary

Overview: The CWFL03820-01430NW48-S000 is a compact frameless torque motor kit designed for direct integration into host machine structures. It features separate stator and rotor components, eliminating the need for motor housing, shaft coupling, and external bearings, thus enabling a space-efficient direct-drive design.

Key Highlights:

Frameless kit with separate stator and rotor for direct integration.
Smallest stator outer diameter (φ37.5 mm) in the CWFL series, suitable for compact joint designs.
Rated torque of 0.14 N·m and peak torque of 0.42 N·m at 3000 RPM on a 48 VDC supply.
8-pole, 3-phase PMSM with sinusoidal back-EMF optimized for FOC servo control.
Class F insulation (155 °C) for reliable operation in demanding environments.
Optional Hall sensor and temperature sensor available.
Customizable stator stack thickness, bore diameter, and winding with no minimum order quantity (MOQ).

NEOTON MOTOR The CWFL03820-01430NW48-S000 is a compact p37.5 mm frameless torque motor kit designed for direct integration into the host machine structure. Supplied as separate stator and rotor components, it eliminates the motor housing, shaft coupling, and external bearings — enabling the most space-efficient direct-drive design possible. The 8-pole, 3-phase PMSM winding delivers sinusoidal back-EMF optimised for FOC servo control, with a rated torque of 0.14 N-m and a peak torque of 0.42 N-m at up to 3000 RPM on a 48 VDC supply. Class F insulation (155 °C) ensures reliable operation in demanding environments including collaborative robot joints, gimbal actuators, and precision rotary tables. • Frameless kit: stator + rotor supplied separately for direct host-structure integration • ^37.5 mm stator OD — smallest in the CWFL series, ideal for compact joint designs • 0.14 N-m rated / 0.42 N-m peak torque at 3000 RPM on 48 VDC • 8-pole 3-phase PMSM with sinusoidal back-EMF for smooth FOC servo control • Class F insulation (155 °C); optional Hall sensor + temperature sensor available • Custom stator stack thickness, bore diameter, and winding available — no MOQ Rated Voltage Rated Current Peak Current (Instantaneous) Rated Output Power Rated Speed Rated Torque Peak Torque (Instantaneous) Back-EMF Constant (Ke) Torque Constant (Kt) Rotor Inertia Poles Insulation Class Weight Operating Environment Ls (Stator Stack Length)
