U3 ServoMotor Series LEADING THE INNOVATION IN HIGH DYNAMIC AND TORQUE AND POSITION CONTROL FOR AUTOMATION U3 Servomotors are available in a wide size range with 6 flange sizes and continuous torque from 3 Nm to 1500 Nm. All sizes (except the smallest size 3) are available in Air Cooled, Fan Cooled and Water Cooled version. U3 Servomotors are designed for highly dynamic control systems. Consequently, motors are designed with minimal inertia rotor to allow fastest dynamic response. Additional inertia an extra flywheel can be introduced in the same brake cavity (as an alternative to brake) to compensate...

Phase Motion Control U3 Servomotors Brushless PM AC servomotors, low inertia, high angular stiffness. Type Brushless PM AC servomotors, low inertia, high angular stiffness. Rotor Sintered, high temperature rare earth, mechanically fastened magnets (without bonding). Insulation The U3 Motor Series of high performance servo motors, produced in the new Phase Motion Control plant specialized in high performance servo motors, is based on the last generation of rare earth magnets and embodies the patented Phase surface magnet assembly technology, which endows the motors with the highest torque density...
