Rated 4.7 out of 5 by 3reviewers.
Rated 5 out of 5 by I installed this motor in a large Air Master air circulator fan, and it has performed tirelessly even during temps that exceed 100F. It starts quickly and runs quietly. I believe the motor was a great value for this level of performance. July 18, 2012

I have an old (ca:1984) belt drive fan that has burned out and needs to be replaced. The part number on the motor is S55JXDLE and is 1/3 HP 1725 RPM SF10. What is the equivalent motor today?

Answers

Answer: 
This motor is not designed to be throttled down due to it's design. We do have motors in our system that are designed to operate at two speeds. Please look at our 5ELK7 as it can operate at 1,725 RPM (1/3HP) and 1,140 RPM (1/11HP).

This motor has an auto thermo reset; therefore there is not a reset button on it. When it cools down it will reset itself automatically.

1 Person needs an answerI have this question too

Answers

Answer: 
No, because both motors are designed to operate at the same speed which impacts the blower and air speed. Some try to upgrade to a motor to the next higher RPM of 3,450. This is usually disasterous because that would require a motor 5 times in HP that would never fit into the original space allowed for the motor. It is best to save time and money and upgrade the whole unit. If you need help on that, give our HVAC Team of specialists a call at 1-800-Grainger.

Answers

Answer: 
No, since both motors have the same RPM, there will be no measurable air flow increase. Some try to do this with the next higher speed motor at 3,450 RPM. That will usually prove disastrous because the horsepower would have to increase 5 times to prevent the motor from overheating and normally that large of a motor would not fit the space allowed by the original design.

There is a start switch in our 6K778. This motor has been in our system for over 10 years with different revisions using different components. It would be best to give us a call with the specific revision letter (right after the 6K778) off of your motor to identify the correct replacement part. 1 800 Grainger

Answer: 
No, split phase and capacitor start motors can not be speed controlled due to the dual start and run windings and the switching device that operates them. There are other options so give our Technical Product Support Team a call for some other options. 1-800-Grainger
