MrNumbskull13 Posted March 5, 2014 Posted March 5, 2014 (edited) My third party 380 motor came in the mail yesterday. The motor takes in 1.25 amps I think but it will only spin for a few seconds, I think this may be due to how much power the Battery box or the IR reciever can deliver. My question is does anyone know how much power they deliver and if it is recommended to 'remove' the overload protection? My other question is; is there anything I can do to the motor to make it need less current? I noticed PF motors have 'things' on the back of them if you open them up. I'm not sure what these things are or if my motor needs them. Any help is appreciated, thanks in advance! Edited March 5, 2014 by MrNumbskull13 Quote
AndyCW Posted March 5, 2014 Posted March 5, 2014 The battery box can provide up to one amp. V2 RX can provide up to1.5 amps per channel. Removing overload on battery not a big deal. Building a relay to bypass rx not a big deal. Getting full power out of your motors priceless! I don't know the answer to your question about removing the capacitor. v/r Andy Quote

MrNumbskull13 Posted March 6, 2014 Author Posted March 6, 2014 Wow, thanks guys! The only issue is that I only have a V1 receiver, does it deliver a lower current than V2? Quote
Philo Posted March 6, 2014 Posted March 6, 2014 (edited) My other question is; is there anything I can do to the motor to make it need less current? No... except putting less load on them! I noticed PF motors have 'things' on the back of them if you open them up. I'm not sure what these things are or if my motor needs them. Any help is appreciated, thanks in advance! This device is not a capacitor, but a thermal fuse limiting current in the motor for safety reasons. Here it looks like the power to your motor will be limited by receiver or battery pack anyway! The only issue is that I only have a V1 receiver, does it deliver a lower current than V2?Yes it does! V2 is able to supply 1.5A per channel, 2A and more for short time, while V1 is rated 600mA per channel, 1A for short time. More details here. Edited March 6, 2014 by Philo Quote
MrNumbskull13 Posted March 6, 2014 Author Posted March 6, 2014 (edited) Thanks for clearing things up Philo! It seems I may need to buy a V2 receiver... Edited March 6, 2014 by MrNumbskull13 Quote
AndyCW Posted March 6, 2014 Posted March 6, 2014 Thanks for explaining what the element on the back of the motor was. I was wrong. v/r Andy Quote
