But that thing was what, 11 kRpm per Volt, some 80 kRpm then, which means a torque of 0.2 Nm?
Difficult to translate to a 500 kW motor, isn't it?
As said. they will not need that sort of power. thats close to 2000hp pr tonne...
a 500watt brushless motor is very managable. Even more so when they go full scale and are allowed to run more poles etc.
Gearing will not be a problem. Biggest gains is to be found in electronics thats where RC cars probably is more advanced compared to their motors. And they are still developing the ESCs in race pace. More power and smaller size.
In the link Tenmantaylor provided the motor is smaller than the ESC. (Electronic Speed Controller)
Im not sure about its weight but in rc car world the motors is around 170grams and ESC is around 40grams.http://www.lrp.cc/en...regler/details/
They also said that they got issues with top speed. The ESC for RC cars go around that by altering the timing to make it rev more. its on a decline now but in the last 2-3 years there was usually allowed to have dynamic timing in most stock classes. this ended up making a 10.5T (typically 300watts now) way more powerfull than a motor without dynamic timing/boost/turbo in the ESC. one of the offsets was that some ESCs made the motors kick like a mule once the correct rpm was achieved. Later came more true dynamic timing systems to smoothen things out.. And then stock racing become blinky classes where no dynamic timing is allowed. they now only allow endbell timing who makes the motors run very hot.
Modified still allows dynamic timing. But its rarely in use. Unless they drive a tight twisty track with one big straight.
Endbell timing has been around since the beginning of RC cars.
