Ultract II
Brushless Servo Motors
for Industrial Motion Control

High Response AC Servo Motors designed to meet the demanding performance and reliability requirements of the motion control industry

Ultract TW

     The Ultract II series of brushless servo motors was conceived and designed as an advanced and homogeneous range of high performance servo actuators, in line with the evolving demands of the automation industry, and particularly suited for direct drive applications.
     The Ultract II servomotors reach the highest torque to size and power to size ratios in the industry. They are designed for sinusoidal control and embody, as standard feedback device, a 6 track sinusoidal optical encoder, custom designed for motor operation, with independent bearings and high temperature rating (120°C), which offer an absolute resolution of 8 million points/rev thus affording the best motion uniformity even at the lowest speed or multiturns encoders with serial interface and electronic nameplate. With this features, the limits of mechanical transmissions are overcome and a vast range of applications can be transferred to direct drive technology.
     The Ultract motors range from the Size 2 miniature servos, starting at 0.2 Nm, which fit in a 55 mm square frame, for micropositioning, small components handling, DC and stepper motor replacement, to the Size 13 large motors, which reach to 450 Nm and 60 kW, intended for direct, distributed drive of continuous process lines, in view of the progressive elimination of long transmission shafts. Standard windings are available for many speeds and for 220/240 and 380/460 Vac for all sizes up to 7. Sizes 10 and 13 windings are for 380/440 Vac.
