Twenty seven years is a good run on a motor. Although I have one in a table saw that sees more use and is over thirty five years old and still running. I appreciate your answering the post and your input.
Huge difference between those motors.
The 120 VAC motor for your saw, is, if you wish, designed for rugged use, and lots of it.
On the other hand, the 12 VDC motor in your furnace, is designed for reasonable service, on a moderate basis.
The huge difference is also the price of saw motors, which are usually less than the furnace motors.
