With the introduction of oil cooling
and with the assistance of an external oil pump and a heat exchanger to cool
the oil, the continuous horsepower and torque from this motor will be higher
than our standard steel frame motor line.
This motor has been designed with the
marine industry in mind, but it can be adapted to any other mode of
transportation. The motor includes a stainless steel frame with the shaft of
the rotor being made of stainless steel too. With anodized aluminum end bells
and junction boxes, the motor can stand up to a salt environment.
The motor is the same 8" diameter as
the standard steel frame AC-3Xx2 motors but now with the use of a junction box,
the total height is a little over 11".
The motor is totally sealed which
allows for the oil to cool all the internal surfaces of the motor.
keep in mind that this new oil cooled design was made with the marine industry
in mind. On a marine vessel there is a constant flow of cool lake/ocean water
that is supplied to the heat exchanger to cool the oil effectively. If these
new systems are installed in anything other than marine, performance results
may vary based on how cool the oil is returning to the motor.
of this motor is around 195 pounds (88.45 Kg).
