Sicme Motori Permanent Magnet Motors

Series SJ - Permanent magnet 3-phase synchronous motors with low inertia frames 100-280
SJ series permanent magnet synchronous motors have been developed in 4 shaft heights, with torque up to 3580Nm.
The main feature of the series is the extremely low rotor moment of inertia, so that these motors are suitable for applications where a very high dynamic response is required (for example, carton and paper cutting machines).

Frames 100-132-160-280
Torque from 43 to 2200Nm
Insulation class F
Small dimensions and very low totor inertia
Speed regulation from 0 to nominal speed at constant torque
Most common accessories available on request (pulse generator, revolver, brake, heaters, thermal detectors, etc.)

SQ series permanent magnet synchronous motors are available up to 800KNm torque
Frames 180-355, with torque up to 8350Nm, are on catalogue, while higher torques are available under specific request.
These motors have been optimized for the direct drive of operated machines, thus eliminating the gearbox.
Typical applications are extruders and paper machines..

Series ST - Permanent magnet 3-phase synchronous liquid cooled motors for low speed applications (Torque motors) – torque up to 15kNm - frames 132-355
Series ST permanent magnet synchronous motors have been designed for applications where the motor is directly connected with the load, to avoid to utilize mechanical equipments such as gearboxes, pulley-belts, etc.
The hollow shaft allows a better integration of the motors into the machine structure.
To reduce dimensions, these motors are liquid jacket cooled, in such way obtaining also a very low noise level.
Higher torque are available on request (out of catalogue)
