Title: 380 motor
Post by: plug on January 22, 2015, 01:02:36 pm

Howdoo, been having a mooch and come across this motor, on the label it says rs380s - 5316 dc 2.4v, is that the maximum to run it on or will it work in the normal 380 operating range 3v to 6v

regards Jack.

My guess, its probably from an electric screwdriver or portable battery operated hobby drill, designed for 'working' revs at low voltages. So probably not. Best option would be to spin it up at about 4.8v, if it sounds like it is doing a million RPM with an accompanying great big spark when you hook it up, don't put it in a Tug! Otherwise it may be okay up to about 6v.

Try it on higher voltages, if it screams, it's not happy!   ok2

  Good advice Martin! I don't think I would use it with the price of motors nowadays think fire. I had a Yorkshireman Tug that the previous owner said ran on 12volts duly tried it with a 12v 7ah and you could have water skied behind it at full throttle the thing almost wheelied. We then tried it on 6volts and bingo proper scale speed and it looked right. Its a very dark art electrics.
      Cheers,

380 motors are generally rated at 7.2v or below. The rule seems to be don't load them over 10A or there will be much smoking and shrieking, followed by melting of bearings and probably the ESC. At less than five quid for a brand-new one it's not worth the risk to life and limb!  :o
