Subject: [alt-beam] Re: BG Micro Motors
They are very nice motors. Good gear boxes, small size and light weight
(compared to MECI motors for sure!). They use a little more current than a MECI
motor with a light load, but the gear ration is more powerful and the balance is
nice. 2 245 chips or an H-Bridge will drive them. Also, don't use a 100 mA
voltage regulator for 3 of those motors, cause it'll BURN you!!! Wow was that
hot. I know it cant source the curent the motors want, but it was a temporary
till I got a permanent solution. Without a regulator, it literaly jumps like a
wild bull. I need to reduce the voltage going to the motors. Waiting for new
parts. Till then it'll run a few steps and I shut it off.
Seriousy, the motors are great for walkers. Good luck finding them. They costed
me $17 each,a dn at a quantity of 24, that is a hella big price tag! I also
bought all of All Electronics remaining stock. They don't expect to see any more
(the person openly sai that to a buying customer). Look out at BG Micro and All
Electronics, even if they say they don't expect more.
