ROV Thrusters

Projects Discussion and Showcase Robotics
#1

Hi. We'll be creating a ROV for our robotics class. We'll be using a 12v 2200 kv outrunner brushless motor for the thrusters. Will it be necessary to use an ESC? If yes what ESC should we use? :slight_smile: Thank you

#2

Yes use an ESC, use one that's well able to handle the load current. You haven't given much information
to go on...

#3

This are the specs of the brushless motor we'll be using.

KV: 2200rpm/V
Max Efficiency: 80%
Max Efficiency Current: 4-10A (>75%)
Current Capacity: 12A/60s

will a 20A ESC be enough for this? thank you

A 20A ESC would be appropriate.

As an aside, the Kv rating of your motors is pretty high for use as thrusters.

How about a 1000kv motor? Do you think it would be better?

Yes. As a comparison, the OpenROV uses 700Kv motors.
