Brushless torque motor CWFL07633-18030NW48-S000

synchronousthree-phase36 V

Product overview
The CWFL07633-18030NW48-S000 is a φ76 mm B-series frameless torque motor kit offering 1.80 N·m rated torque and 5.40 N·m peak torque at 3000 RPM on 48 VDC. This 10-pole, 3-phase PMSM with sinusoidal back-EMF is optimised for direct-drive applications such as industrial robot joints, rotary tables and large gimbals.
