Brushed motor dyno

[integra22t]

Back in the 90s I used to have a motor dyno that I would like to find again.

From what I can remember it was about 6x9x2 in size. Two sweep needles One for amps and one for rpm. The motor sat facing into the box and was held with 3 finger screws. The motor had a magnetic cam on the shaft. One of the reasons the motors face was facing in. It had a knob to adjust rpm, and it was black with a silver face.

I've done some searches but cant find the right one, and not knowing who made it doesn't help.

thanks

Shinwa made such stuff. Can´t remember of any other.

Yes, by your description I think V10 got it- the Shinwa Motor Dresser

[integra22t]

just seen that one the other day and its nice looking but not quite the one i use to have .. one too many gauges and a little long ... but close .. why did i never take picts of my rcstuff grrrr

[GoMachV]

The only other one I can think of was the Aristocraft Motor Conditioner, it was very similar to the Shinwa though. Probably made by them

[integra22t]

The three screws, sounds very familiar but I can't recall the maker. Build your own, it's not that hard. I got one from Deiter and copied it and made several more. All components from radio crack. Basically you have one motor driving your "test" motor. The drive motor is wired for amp draw and the "test" motor is wired for voltage (rpm). You can put in a couple different resistors to "load" the motor as well. That dyno is one of the few things I wish I had kept.

thanks spru but shipping is more than the item lol

i miss mine too ASC6000 .. when i had it i wanted a diffrent one with a slave motor so i could get my tork curve .. but i did quite well with the one i had

Heads up....
There's a Shinwa on eBay, ending in just under 5 hours. Currently at $35 ($10 shipping).

Item 231283997889.

(I don't know the seller).

I'm a noob, any advantage to this type of dyno over running the motor under water?

[integra22t]

thanks for the heads up .. it whent for 75+ 35 to ship to me

the idea behing it is to test and tune brushed motors .. water is a great break in and have done it for years

Running under water will bed in the brushes faster, but that's all it does.

A Shinwa Motor Dresser will let you tune the motor, so you can see the effect of different brushes and springs, and adjusting motor timing. The numbers on the meters shouldn't be assumed as accurate, but they do give you a good comparison between different motors and different settings on a motor.

Thanks for the information. Glad you got it Integra. I know I ask a lot of noob questions, so I try to help out when I can.

[integra22t]

Sorry to redirect this thread, I found my old motor dresser in the loft, which might be the one you used to have.
