A few questions about brushless motors (and motor scaling)
Hi all !
I am currently working on a new robot that will involve tracks. The electronic prototype is under progress and I start thinking about the mechanic part and many questions keep popping into my head, maybe you can enlighten me ;)
- First of all, I keep reading how great brushless motors are. Does it make sense to use that kind of motor with a tracks/wheels robot ?
- When I choose a standard DC motor, finding one with a fine gear reduction that suits my needs (torque, speed) is not too difficult. Same with servos. When it comes to brushless motors, I get lost ! I can't find anything about reduction :( It is not an issue when it is about moving something light (like a propeller), but for a wheels/tracks robot, it becomes a prbl. Any idea, or am I missing something ? :)
- Last question, more generally, about motor scaling. How do you choose the best motor for your project ? For instance, you know the approximate weight of your robot, the maximum speed you want it to reach and the number of wheels/tracks. How do you determine which motor is required ? Do you apply some physics or just choose a motor with the highest torque ?
Sorry, quite a lot of questions ;)
Thx for reading !
