Three-Phase General Purpose Motors
WEG Open Drip Proof (ODP) motor is a general purpose
line designed for environmentswhere dirt andmoisture are
minimal. The ODP cast iron frame is designed to provide
maximum ventilation and heat dissipation, offering low
vibration levels, high mechanical stiffness and durability.
Widely used in applications such as compressors, pumps
and chillers, the ODP motor line meets or exceeds the
efficiency levels determined by International Standards
and the minimum efficiency level programs in force
worldwide.
Inverter Rated:
1000:1 for variable torque
