Characteristics of the range


Proposed in three diameters, 145 ,190 and 300 mm with a large variety of position feedback: resolvers, encoders and a variety of shafts: hollow, blind or solid shaft. Rated torques cover a wide range between 14.8 Nm and 235 N.m, in natural convection, and the peak torque covers from 55 Nm to 1161 Nm. The motors can reach a rated speed up to 1500 rpm. These motors present an outstanding compacity with a continuous torque-to-weight up to 3.7 Nm/Kg and a peak torque-to-weight up to 18 Nm/Kg. Two windings are proposed as a standard: 500 and 1500 rpm for 145ST or 500 and 1000 rpm for 190ST and 200 and 800 rpm for 300ST. But the winding can easily be adapted to match your optimum drive rating.
