I’m contemplating a direct drive outrunner project, and I’m wondering if some kind of clutch/mechanical overload prevention device is advisable in this system.
I’m new to the world of ESCs and BLDC Motors, but I do know that ROV thrusters (pretty similar to this application) usually include a magnetic coupler or similar device to prevent damage if something lodges in the propeller.
This provides safety to both man (hand jammed into prop) and machine (slip instead of break).
Do the current overload protections available with an ESC make this unnecessary? Or should we still be looking at using a friction clutch of some kind with systems like this?
