Homebuilt ROVs Forum

I want to use brushless motor but I don't know any thing about these motor
I want to how brushless motor work, how can I control it, it's waterproofed or need a housing,

I used before brushed motor and control it by relays and H-bridgs,Are brushless like this


thanks

There are a lot of people using brushless motors without housings, that's not to say they are waterproof but some of them still work. Some people have actually tried waterproofing them with epoxy. I think there was info on the forum somewhere but I don't remember where off the top of my head.

As for controllers you will need some type of brushless motor controller they will not work off of a relay setup. R/c speed controllers are usually the easiest way to go. Again there is info on these in other threads on this forum.
