Brushed motor dyno to brushless conversion
Hi all
I have a Trinity monster horsepower motor dyno for brushed motors from eons ago (been out of the game for a while). Is it possible to convert these for use with brushless motors? Main problem is the 3 phases input on brushless motors compared to positive/negative input on brushed motors.
Thanks for your help

The Orca BMD Brushless Motor Driver is designed specifically to convert brushed dynos to brushless.

All you need is a cheap brushless ESC (I use a HobbyWing Just Stock) with no timing. A spare receiver and a transmitter radio. Set both the radio and the ESC to get to max power as fast as possible when the throttle is pulled. I run the receiver off an external battery pack. Then its a matter of hooking the ESC + & - terminals to the power leads from the dyno that used to be solder to the brushed motor. Hook the ESC to the brushless motor just like you would if the motor were installed in your car. Then its a matter of starting the dyno and pulling the throttle on the radio at the same time.

Really depends on how fast you can get from zero to full throttle by turning that knob. I can pull the trigger on my radio pretty fast, plus I can put exponential to get to more throttle faster too with my radio. Between the ESC and the radio the main objective is to get to full throttle as fast a possible to make the dyno think it's testing a brushed motor.

Who said you can't teach old dogs new tricks? Well this old dog learned something new, holding the throttle at 100% then running the dyno works on the Fantom dyno too. The motor makes a horrible cogging noise until you click on the run the motor button, but it works. For me, I happened to have all the spare parts I used laying around my workshop, so it was a no cost solution.

Is the ORCA BMD still available?
