CD-rom motor-test-stand


hey

I just made this teststand and thought you should see it.
The 2 multimeters are build together, the esc is connected to a homebuild servotester and as you can see the motor is put on a letterweight. I test all motors as a "pusher".
I just connect the accu I want to use in the setup, to the meter on the right, turn the button on the "nice blue" box , and now I can see Amps, Volt and thrust. My plan is to put a rpm-meter on it too.


What do you think, smart isnīt it.

I simply used some very strong dubblesided tape I had ( I don`t know if it is called that, but you know the kind of tape with glue on both sides), but you could use any kind of glue or epoxy.

sorry if my english is a "little danish", but there is a reesson

here are some closeups:

I would get a large piece of plexi glass or lexan prefered to use as a shield just in case your closely looking at the readout and the motor throws a blade.

What 'blade' did you have spinning at 87,000rpm and what motor was spinning it?

Hi Iīm back

I have now put a tachmeter on my test-stand. It gave me some problems but now it works.
I took the "eye" out of the tachmeter and placed, pointing down,it in the white plaststand you can see on the picture. Then I placed a small diodelight on the scale, pointing up, now it works great.

Now I can see A, V, rpm and thrust at the same time, what more do you need

What do you think of it? donīt you think it is a little smart

You could put a microwave next to it so you can have fresh popcorn while testing how long will the motor fly full throttle on a fresh pack of batteries
