Restoration ESC question
« on: March 04, 2018, 06:21:15 pm »

so i have a Tug im saving from the Scrapheap...
its the Caldercraft 1/25 Alte Liebe Kit, it already has a motor that im told is 12v
but i dont know what motor is is, or its power requirements so i figure id throw the question to you fine fellows

its nearly 100mm long ( although it does have a gearbox on the end of it ) and 50mm wide
im either going to be running 9.6v or 12v depending on availability of batteries

i was just looking into getting the Electronics sorted and the ESC rating came up, and im out of my depth ( if you will parden the pun )

this ESC was recommended by a friend in the RC car market, although even he said he didnt know really what to suggest

Looks like a Hectoperm. They are often marked with the voltage, doesn't appear visible in this case. There are 6v and 12v versions of this motor, not much help there. If you are running through the geared output, the current drain shouldn't be too high, less than 10amps any day of the week. So a 20amp controller should be more than suitable. Overkill is no crime in this sort of situation though!

Have a look at this

P80s Condor 20/2' Autoset Computer Speed Controller For 7-12 Pole Motors ACTion Electronics
If something does go wrong with it there would be more chance to get it fixed.

The Turnigy speed controller would be no use to you, it's for a brushless motor and you have a brushed one. The way to tell is a brushed esc has two motor wires and a brushless one has three.

OK Lilgoth, yes it's a Hectoperm motor, I'm 90% sure that's the 12 volt version. In this set up it will be drawing between 3 and 4 amps assuming a sensible propelor is fitted, I.e less than 80 mm.
  It's a 5 pole motor, so a standard ESC  will be perfect, not a brush less type, not a 7 pole plus type.
  Most people have a favourite brand and some are rude about any type they don't use themselves, but mtronics viper 15, electronise and Action are all very good.
 I recommend the Viper 15 because it is reliable and completely waterproof.
  Other opinions about brands are equally valid.

I should have added that the Hectoperm is a top quality and highly regarded motor. It may be old but it is very good so take care of it.

I Echo Chas, £40 - £50 and new if they are still available nearly 3 times that.  On direct drive it will handle a prop of similar diameter as motor.  They run forever.
