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 bought a Cobra drain snake from Lowes and the motor locked up. I need a replacement. The specs on the Cobra snake motor is; single speed 1/3 HP - 1725 RPM - 115V - 5.7A - 60HZ - 1/2" DIA shaft. Shaft length is shorter but nothing will be in front of this one. It also has a switch and housing screwed and wired on the side for FWD/REV.

Answers

Answer: 
The Dayton 6K778 is a fan motor, it does not have the switch on it. The motor that you have was custom made for Cobra and we will have to order it direct from them. That motor was custom wound to work with that reversing switch.
Please call Grainger at 1-800-GRAINGER and we will be happy to help you find the right motor.

The 6K778 motor does not have enough Horse Power to run the 1AHB1. Grainger item # 7AR60 will be a full package with the proper motor, belt, pulleys and will include the 1AHB1.

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

Answer: 
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

1 Person needs an answerI have this question too

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.

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.
