Surplus motors

[rutexus]

Gentlemen,

I plan to put .5 ohm resistors in each leg of the 1000 watt Sanyo motors. I ordered 6 1 ohm 50 watt resistors to do the job. If I had a source for .5 ohm resistors, I would have ordered them. I believe these motors need these braking resistors to be used with the R992 and R2030 drives.

I haven't received my resistors yet, and have not hooked up the 1000 watt motor yet.

I hope to get to it this week, but I will be off a couple of days this week and away from home over next week end.

retexus: if you need those resistors let me know, my local guy carries them and said he would ship too. shoot me a pm if you are looking for anything like that or are still looking for those .5 ohm resistors.

is there a part # for those resistors so we can order them online, I ordered the 400w motors, so I'll have to see if they have the brake.

Thanks

I am always interested in new sources of components so that I can help others find the parts they need.


Please share with us the info needed to contact your source of .5 ohm resistors.

i dont own the shop and they are basically a local electronics surplus yard with a buttload of ecg stuff, anyway here is the stuff you will need to know.

the name of the place is pembleton electronics, it is in ft wayne in
the phone number is 260-484-1812
ask for ross

if he says they wont ship or gives you any crap about something pm me here if you find they have something you need and they get nasty with you.

Tom, do all the different size motors need the resistors, or just the 1000W? If all, do they all need the same size resistors?

[rutexus]

Thanks, H20 for the resistor info.

I believe only the 1000 watt motors need the braking resistors.

Where are the "drives" or "encoders" necessary to run these? I would love to upgrade to something like these. I saw someone mention $200, but was that for something like a Gecko, or an encoder that goes on the motor? I would like to get the 1000W motor, but what oz/in does that equate too? I guess they can just do much higher RPM and still have torque? Thanks in advance!

I got one of my motors here up at college today. One thing I noticed was that the motor wont spin, i am assuming that the brake is on unless power is applied to it, but I also noticed that there is a slight amount of play when I try to rotate the shaft, its like 1/2 a degree at most but it is there. Is that common or is something wrong with it?
What wires are the brake wires?

let me know,
Jon

The brake is on until 24V is applied. I got the 300w without brake, and they turn smoothly. I think the play you feel is the brake.

William, the encoders are built in. You need either the Rutex R992H or R2030. www.rutex.com

I don't have a motor but the spec sheet says .33a at 24v so you should have a pair that have ~72ohms across them.
All the rest will be either very low ohm (Stator) or much higher (encoder).

Yes, I belive the brake is what I feel too. The brake is only used to slow or stop the motor and not to hold it in place right? becuase if it was to hold it in place, there wouldnt be play.

btw, the drawing I posted earlier is way off, I went by dimentions on a website and they are way off.
