I’m afraid we don’t know much about these, hence the very cheap price.

We have found they are USA manufactured by MET motors.

We have found a drawing of the dimensions which is in the photos, dimensions are in inches as it’s USA manufactured.

We don’t know RPM, Horsepower or any other specs, but, they have been tested and working and seem a nice powerful motor.

We have 2 types available, but they were all removed from the same machinery, so we presume the specs are the same between them, the only difference we can see is the silver version has removable brushes whereas the black version doesn’t. Please use the send seller a message to state which version you’d prefer (black or silver) or we will send either.

We have many of these available.
