Made a new engine. For the first time, an error was made in the air gap between the stator and the magnets. He was too big. Now the air gap is 0.5 mm.
I drove the first 200km with a new engine.
What can I say... before that, the scooter did not go :-D 100 km/h is gaining imperceptibly, even on a serious climb. Checking the maximum speed is still scary... at idle, it turns 126 km/h, I think 110 will definitely go confidently.
I started the cooling system after all! Works better than I expected! I made two laps around Yalta without stopping, for 52 km, the temperature of the windings did not rise above 44 degrees, at an air temperature of +12
I measured the acceleration 0-60 and 0-100. The first time I set the Nucular controller settings to 500 A phase and 290 A battery. It was necessary, of course, to train for a couple of weeks first, before the race... The data is not objective, since up to 70 km/h, it is not possible to squeeze out full throttle...
As a result, it turned out 0-60 km/h - 3.29s and 0-100 km/h - 6.53 s, the maximum power is 24.2 kW, While shooting several takes, the engine warmed up to 47 degrees.
