Description
Compared with its predecessor, it has higher power density, a wider speed range and lower rotor moment of inertia. The first frame size, DST3-135, has six mounting lengths. The moment of inertia is 0.057–0.161 kg·m², the standstill torque M0 is 175–755 N·m, and the maximum torque is 340–1260 N·m, these being maximum values. The housing is smooth, thin and solid, so dirt does not stick to it, the main connection is through a terminal box, and the protection rating is IP54. The shaft can be solid, hollow, with a thrust bearing for the axial forces of a screw, or with a blind hole, and bearing relubrication is available to order.
How to choose
The type code describes the frame size, length (AA…FF), protection rating IP54, cooling type (W for liquid), rated speed class (017 for 175 rpm, 035 for 350 rpm and so on up to 200 for 2000 rpm), DC link voltage 540 V, encoder type and shaft version. Feedback is provided by a resolver, Hiperface encoders (SRS50, SRM50) and EnDat 2.2 (ECN1313, EQN1325, ECN1325, EQN1337), as well as inductive ECI1319 and EQI1331 Gen3. Options include an electronic plate (E-Type plate) and safety functions. The motors run from b maXX servo converters with a 540 V DC link. For larger frame sizes, up to 560, see the DST2.
