There are motors out there that will operate in sensored or sensorless mode depending on the mode the controller uses. Aren't sensorless systems more efficient in racing conditions?

urmmm. i didnt think sensorless was legal for racing? well.. at least here in Australia anyway.... ??

I think sensorless controllers are legal for racing. Look at the Tekin R1/R1Pro. Most people use the sensored to avoid the start up problems some sensoless controllers have with slotted motors. The motor is the one that ROAR seems to have a problem with as they must be Wey wound and I think a few sensorless motors are Delta wound. A sensorless controller will control any kind of brushless motor. I used my MM to run a Novak HV4.5 motor. All you be doing is not connecting the sensor plug. A sensorless controller uses BEMF to sense where the rotor is and a sensored uses hall sensors. The Trinity N80 for example is a similar designed motor as a sensored Novak, but the N80 is sensorless and I used my HW controller with it. Sensorless techology has come a long way. Some sensorless controllers now have amazing start up and can compete in racing I think.

maybe it was the motor im thinking of...

Scientifically you're probably right. But the perception right now is sensorless=entry level/cheaper products. And being that is that way, they're going to have a tough time selling by far the highest priced ESC out there with the way people look at sensorless.

I'm not disagreeing with you. I was just pointing out that sensorless has lesser performing, lower quality stigma attached to it in touring. I know very well that 1/8 scale is all sensorless, so it obviously works well.

Did you notice at what alarming speed Tekin does update there controller, There is a lot of room for improvement. BTW Xerun startup sensored but does run sensorless once launched.

Before you guys get too fancy, the KO brushless speedo is sensored only and doesn't have sensorless mode. This is what the fellow KO collegue told me in Thailand...

Please fill us in on more info when you get them. Thank you. |
Hey, I'm the LRP and not the KO technician... :D
Sorry, don't have further details that are not already mentioned. |

Yes, I'm aware you are LRP. Could you ask your fellow KO collegue for more info? With the good success of controllers that can use sensored or sensorless, it would be good to know if KO will go that way. I checked all the pictures I have of the KO controller and I couldn't see any sensor port. Could it be under the where the motor/battery wires are located?
No final release date for the ESC but scheduled for later this summer. |
