Cooling and lubrication of the ball bearings is provided by a special FDA-approved liquid. The stator is housed in an AISI 304L stainless steel jacket attached by steel pins to the upper motor support. The cable connector is removable to ensure fast and easy maintenance operations.
The cable is ACS, WRAS and KTW certified. The motor is suitable for use with variable speed drive (30 Hz-50/60 Hz). For the single-phase version, the capacitor and the manual reset current protection are placed in the switchboard that can be supplied separately; the 4OLTW version with capacitor included inside the motor is also available. For the three-phase version, protection must be provided by the user.
