Water-cooled servo motor U3 series

brushlessAC480 V

High dynamic water cooled servomotors S1 torque from 13,1 Nm up to 1540 Nm The ULTRACT 3 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. 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 for poor mechanical linkages between the motor and the load. The standard shaft is for the same reason round and ready for clamping with conical hubs (recommended to avoid backlash). If a key is required (and the corresponding reduced servo performance is accepted) it can be supplied as an option. All shafts are balanced so that simple rotating parts (e.g. pulleys, gears) need not to be balanced. All motors can be equipped with a PM safety brake. The brakes are all rare earth permanent magnet type. This new high power density brake operates without brake pads. As a consequence, the problem of pollution of the motor cavity when the brake is operated incorrectly is avoided. Type Brushless PM AC servomotors, low inertia, high angular stiffness. Rotor Sintered, high temperature rare earth, mechanically fastened magnets (without bonding). Insulation Motor: Class F according to DIN 0530.
