RO-Power Torque Brushless motors are lightweight, powerful external rotor motors with high torque and efficiency. They do not require a gearbox and are suitable for a wide range of applications. All components are manufactured on modern CNC machines from high-quality materials. Precise ball bearings increase the service life and minimize vibrations. We recommend the operation of RO-Power Torque motors with ROBBE Ro-Control speed controllers.
