Esc overheating

[Isaac Peel]

Hi all,
I have a hobbywing V2.1 120A Esc which is overheating and doing so it is overheating my batteries and motor which then makes my motor freeze up. I have changed my motor today but it heats up that motor as well.
HELP PLEASE!

The Ezrun system does tend to over heat A LOT,so what you have to do is add a fan to the esc and motor (it looks awful,but with Ezrun you have to do that) and try a different pinion. ( less speed=less waste product=waste product=HEAT)

If your lipos are over heating then stop using the system completely, that's dangerous.

Thanks.

Yeah but I dont think a fan would do much good because even just turning it on and throttling it for a second it heats up, smokes and the engine cuts out.

SMOKES!?!?!??!?

Broken esc mate, thats a goner.

[Isaac Peel]

Yes but sometimes it is the motor smoking not the esc even if we put the new one in we just bought today.

[Nas]

Ouch,in that case return it to the shop you bought it from.

Thanks.

Have you got access to a multimeter? Disconnect the motor and the batteries and then measure the resistance between the battery + connection and each motor wire and the battery - and each motor wire. If any of them show up as a short or low resistance then you have blown the FETs in the speedo and that's why it's heating up
