IE4-PM Synchronous Geared Motors for Explosion Hazardous Areas | Bauer Gear Motor

The S series of permanent magnet synchronous motors (PMSM) from Bauer Gear Motor GmbH now offers variable-speed motors in efficiency class IE4 for use in explosion hazardous areas. This is the highest energy efficiency that can be achieved with the current state of motor technology. Total flexibility in mounting options allow unparalleled integration possibilities.

Generously dimensioned ball or roller bearings,case hardened forged and ground gears,and internally and externally reinforced gearboxes ensure a long,low maintenance service life. A hardened wear sleeve and spray ring at the rotor seal allow for reduced sump capacity,reliable lubrication and many years of leak free performance.

Superior protection of IP65 acc. to IEC 529 assures you that the all geared motors are dust tight and hose proof,and can be used outdoors or in wet and dusty environments without the use of additional enclosures. Full rated output is available at the output shaft of the unit.
