Motor help

[stannyblade]

Bought a new ESC and motor (HPI Firebolt)

When I connect it all up the ESC doesn't recognise the motor (no beeping)

If I connect my old motor the ESC works fine and if I pull the trigger there is a noise from it but nothing works.

Is there a way of testing a motor to see if it works or not?

Got a son here wanting to go back out with it and moaning like mad that his useless dad cant fix it.

Thanks

Fire bolts are pretty poor motors, I've had a couple that were just pants.

As they are a sealed can, if it doesn't work it's basically knackered. You can try giving it a quick tap just in case the brushes aren't sitting on the comm properly, or stick a multi meter on the wires to see if you have continuity (if not then either the brushes of the windings are at fault), but that is about it.

You can hook a brushed motor directly to the battery pack, if it runs, it works.

 

It's not normal for an ESC to "recognise" a brushed motor by beeping, but ESCs do need to be calibrated to the radio.

A lot of brushed ESC's make a tone by 'ringing' the motor on start up. If it works on the old motor but not the new one, there's your answer.

What ESC is it?

The noise is because of the high frequency switching of the ESC, it's not intentional.

On some ESC's it is. Try it with a Tamiya ESC. Motor on it will chime, no motor and it won't make a sound.

I'm not referring to the whine on part throttle, (most do that), they beep as part of the set up menus. On the teu-101 it beeps when the ESC doesn't see a signal from the TX.
