Incorporating Marathon’s patented Max Guard insulation system, Blue Max motors can operate with any carrier frequency and any cable length. Suitable for use with open- or closed-loop inverters, a shaft-mounted encoder option is available for the latter. These industrial motors feature a wide constant torque and/or constant power speed range and are performance-matched to most makes of inverter.
A robust cast-iron construction makes these motors suitable for arduous duties in, for instance, chemical plants, paper mills, manufacturing, construction and other demanding environments.
Features of the Blue Max range include: Class H insulation, constant torque from zero to base speed and constant power to 150% base speed and choice of terminal box mounting position.
Foot- and face-mounting options are available, while the shaft bearings are double-shielded.
The continuous duty rating is 40°C ambient, while temperature rise on blower-cooled motors is to Class B. The Blue Max specification includes Class F N/C thermostats (one per phase). The power range is 40-100hp.
Blue Max meets NEMA MG1-1998 and similar requirements for energy efficiency and environmental protection. The range is UL recognised, CSA certified and CE Mark.
