I would like to know if the BD3 interface is designed to work with water cooled eddy curent dynos (image attached) where the coil resistance is from 1 ohm to 20 ohm.

Usually this dynos work with 10A max and 300v.

Thanks

Looking for and details as to what all needs to be purchased for the conversion.

The dyno was working then abruptly the eddy brake stopped functioning.  Will we need to upgrade the speed sensor? We just purchased a new load cell.

Also, Do you support overnight shipping?

Is there a contact email and or phone number that I might contact someone directly?

Regards. 

hi

is there anyone that knows if it is possible to view the internal loss numbers in ex. curveform?

i know that it can be viewed in analyze when analyzing a run

i would like to view the numbers to see if have set it up right?

i want to ask if there is someone here that can share their experince with the loss calculation on a hubdyno.

i get very stable whp readings but the loss calculation is very different from run to run causing the engine hp to be very different from in the different runs

is there an other way that loss calculation should be done on hubdyno than on chassis dyno?

regards

im building my own hubdyno on a tight budget, im using old telma cc 300 eddy current brakes.

my question here is:

1: is there anyone here that maybe could share a dyno controller setup file, it would be nice to have a kind of start up setting, then i can change the settings to get a startup file for my own hubs.

2: i have only had one car on the hubs 

is it normal that the wheels are spinning at very different speed. i have not had the brakes activated yet

thanks

Did one of you already a hub dyno for tractors? In the end, I have build 2 separated units, where are connected to the tractors rear axle. I have 4 EC per unit, so in total 8 EC (Klam-550). And yes, the 8 eddy currents are needed, as tractor power goes up to 5000hp (Superstock Tractor Pulling).

Speed diffrerence on hub could occur, and should be controlled by controller (the two separated hub's are mechanically not connected- no synchro shaft in between).

Is there a possibility to do something as a "Master" - "Slave" configuration with the DC2 controller, to manage total 8 separate eddycurrent brakes unit (and also read 8 load cell)?

Thanx for some info's. Regards markus

Just purchased an old dimsport braked eddy dyno to help me tune crosskart buggies with motorbike engines. 

It was supposed to be working, albeit even if it wasn't accurate, but straight away the old Rotronics/Dyno Race software packed it in. So I've purchased all Perek components to upgrade it tonight. I will post some photos etc as I go, hoping it will be a straight forward upgrade.

Our old ( chassis ) dyno had a hand held potentiometer to control the roller speed and I found this a bit easier to use than trying to pick up a keyboard to change the settings while tuning .

How do I go about implementing this .

Any help would be appreciated 

Thanks
