300 Amp Motor Controller

Question

I need help on how to hook these up to ezb https://www.r2hobbies.com/1-10-rc-car-300a-hv-brushed-motor-esc-electronic-speed-controller-2a-bec-with-fan.html i received no manual

R2D2 · Answer

It is easy, T-connector cable to the battery, the motor cables without connectors, cable and servo to ez-b, of the latter can cut the red wire because it does not need the BEC

R2D2 · Answer

The link seems not to work for me, but I assume you mean these:  And the red wire of BEC can be eliminated:

yes those are the ones that i have thank you

OK, I need to ask... What kind of motors are you driving with 300 amps? You making a self driving car? A giant killer robot? The motor on my Toyota Prius is only 351 amps. Alan

Rich · Answer

Nope it's 300A according to every web page and datasheet I can find on it. Forward Current: 300A Reverse Current: 150A BEC: 2A Max 5.6V That's one beast of a controller

R2D2 · Answer

I agree Rich, is a beast, but I doubt that the specification of 300 amps is real, do not think the cables or printed circuit hold much current, but if you hold 50 amps continuous to me and I think to most robots will simply so the best thing is the price. I use two engines and truth roomba I disconnected the fan by noise and do unnecessary power consumption

It might be a bit of over kill but better than too small. I am using it for a dagu 4wd chassis. Does anyone have manual of instruction sheet for this.

jdvann · Answer

It is going to be the chassis for my Droid on Guard (dog)

it may well be 300A but its only DC brushed and it'll be for low voltage. I thought the prius was a 3 phase DC input ESC with a working voltage of 500 or so volts. I looked into it a while back and I specced up a 750V Lipo cell to go through a siemens ESC, that was about the size of a PC tower (bigger than the motor).

A huge 300 amp controller could be for a Ducted fan jet or 1/4 scale RC aircraft. There are brushed and brushless motors that draw lots of current for short periods. I built a electric 11.1 volt avatar heli and it drew 160 amps max full throttle and it only weighted 6 pounds.

does anyone know what setup i need in in EZ-build to use this controller?

Dave Schulpius · Answer

I dont have ARC to look at right now but I think you can use a H-Bridge control. synthiam.com/Tutorials/Help.aspx?id=70

jdvann · Answer

thanks will give that a try tomorrow. off to work now

R2D2 · Answer

This controller uses a modified movement panel, as it accepts a servo signal input for control. synthiam.com/Tutorials/Hardware.aspx?id=28
