Water Jacket Cooled Motor
The water jacket cooled WGM motors were designed to meet the
increasing demand for compact and reduced noise level machines,
where high output power versus frame size ratio is required.
Advantages:
g Low noise level;
g Suitable for variable frequency drive operation;
g Minimum thermal dissipation to the environment;
g Compact construction;
g Suitable for aggressive operating conditions.
Types of applications:
g Marine duty: main and positioning propeller, pumps, etc.;
g Cement: kilns, mills, conveyor belts, fans, vibrating equipment, etc.;
g Wind energy generation;
g Mining: crushers, mills, conveyor belts, compressors, fans, pumps, etc.;
g Pulp and paper: chippers, mixers, debarkers, refineries, etc.
g Petrochemical: pumps and compressors;
g Water and sanitation: pumps;
g Steel industry: fans, exhausters, laminators, pumps, conveyor belts, cranes, etc.;
g Sugar and alcohol industry: chippers, debarkers, mills, etc.

Construction features
The water cooling system for WGM motors is provided by
circulation of water over the frame construction and endshields.
Besides allowing an effective thermal exchange between motor
and the water, this cooling system reduces the temperature of
the hoses along the grooves and increases the output power
versus frame size ratio.
Additionally, this system maintains the thermal efficiency, even at
reduced speeds, which allows the application of this motor with
frequency drives at high speed range on severe application that
requires constant torque.
The water cooling system also minimizes the heat exchange
with the environment, cools down the bearings without requiring
independent cooling system along with keeping low noise level.
