Brushless motor CW-63BLW33-40L220-02

DC3-phaseBLDC

Overview
The CW-63BLW33-40L220-02 is a 63 mm outer-rotor 3-phase brushless DC motor engineered for direct-drive, low-speed high-torque applications. Rated for 24 VDC supply and 2000 RPM, it delivers a nominal torque of 200 mN·m at 2.75 A. The outer-rotor construction increases moment of inertia and smooths torque output, making this motor suitable for direct-drive fans, cooling modules and ventilation equipment. The unit provides an 8-lead interface with direction, brake, clock and load-detection signals for system integration.
