Details

These motors are available in aluminum in frames 56-160 in three phase, single phase, double speed and for inverter duty versions.
One of the unique features of these motors is the modularity and versatility of the assemblies (B3, B5, B14, B34,B35 ). Both feet B3 and flanges B5 and B14 can be removed without opening the motor, enabling an easy change of mounting arrangements. The terminal box can be located on all the motor sides and the cable entry / exit can be turned by 360°.

The motors are built according to European standards: EN 60079-0; EN 60079-1; EN 60079-7; EN 60079-31.
