I agree with Jared, the motor in the link you sent looks like it has sealed
bearings. if it has a squeal it is likely a bearing is going out. Take a
temp reading when it starts to squeal, chances are it is above the design
spec not listed in the link. This motor is totally open fan cooled, it uses
the surrounding air to remove the heat to keep it cool. Find a way to vent
cooler air to keep the temp down if you want to extend the life of the motor
and bearings. . Totally open motors are designed to run in a very clean
Larger more rugged design motors TEFC (totally enclosed fan cooled) usually
have grease ports.
