Motor info: 1) 12v dc 775 original motor 2) 21000 high rpm Only 1 time used for check.. I bought this motor only 3 days ago. I ran it only once within that time, it is way too powerful which is not going to be useful for any of my work. That's why I am thinking of selling it. This is not like any other motor in the market, it has double bearings in front and back meaning front and back, and a cooling fan inside. These are sold at a very high price in the market, I bought it at a high price too, but now since I have to sell it, I am giving it for less. You can take it 100% worry-free, if there is any problem, you can return it immediately. You just need to pay the delivery charge to receive it, check and inspect the product before making the payment.
