Designed with the aim of addressing new industrial needs, has created ST low inertia motors range for DIRECT DRIVE allowing acceleration up to 20 000 rad/s. ST range is proposed in three diameters, 145, 190 and300 mm with a variety of hollow shafts up to internal diameter 75 mm, blind shafts or solid shafts. Rated torques cover a wide range between 14.6 Nm and 235 Nm in natural convection, and the peak torque covers from 55 Nm up to 1161 Nm. The motors can reach a rated speed from 200 rpm up to 1500 rpm according to the windings and allow a high regularity of rotation at low speed.Those motors...

Optionally STK armatures and rotors can be shipped mounted on a centering and positioning flange for avoiding the user to make the operation of mounting and centering the rotor inside the stator. > The armature is the source of both current losses and hysteretic and eddy current losses. It will be necessary to take it into account for integrating the motor. Here are the main elements to be taken in consideration:-Permanent torques of the motors are indicated for a copper temperature rise of 120C for armatures in contact with ambient air or integral on all their peripheral area with a metallic...

Various positioning sensor interfaces: the drives can be compatible with 4 kinds of positioning interfaces:-Resolver:The resolvers are in the best cases ( resolver RES FC6 72 32) limited to an accuracy of 1 arc minute. In most of the resolvers available on the market, accuracy is rather around several minutes.It will be necessary to check whether the desired positioning accuracy is compatible with the resolver accuracy and also the electronic resolver-to-digital circuit. On another hand, the resolvers limit the applications due to the crossing hollow shaft. The resolvers RES FC6 72 32 allow a...
