I am currently building a hobby-weight (5.44kg) robot. The weapon will be a vertical spinning disk at the front. It will probably be a commercial one from the hardware store or I could maybe get one made.
I have 2 cordless drill motors to drive my wheels so I should be ok there, but I am still lost where it comes to what motor I should get for my weapon. I am now inclined to think it should be brush-less although I am still open to other opinions.
Can anyone please recommend a good motor (in-line brush-less) or brushed motor that will give me the speed and strength I need for the weapon?
