Re: Calculating motor heating?

In your calculation you don't speak about cooling. 1. Cooling by the metallic mass of the motor. 2. Cooling by the speed that air-cool your hub. 3. Cooling if your motor use a fan (drone, skate,...) motors. Cooling is very important and you have to take it into account, but often it's very difficult...

Re: VESC FOC for a flywheel application....

VESC 6 seems to be reliable up to 100krpm.

Ready-to-use Trampa VESC6 is tested and reliable.

See also Stewii test here http://www.electric-skateboard.builders/t/hw6-4-based-esc-escape/37579/219

Have a Nice Day.

Re: Setting a speed (RPM) using UART

14 poles = 7 PP "Pole Pair".

571rpm x 7 PP = 3997erpm.

So that's right !

Re: DRV8302 faults with FOC

Not really.

A very good 2.2µF is better than a bad 4.7µF, the size is important, the larger the better.

See the link given above to check the parameters on the Murata Website.

Other Manufacturers have also this kind of tools.

Have a Nice Day.
