*At 10,000 rpm, each rotation takes 6 ms. If we have 10 magnets, then we have 0.6 ms over which to control the on-off of magnets. Since we need to divide that at least by 10, and more like 100 - so we need to have about 6-60 microsecond control over the turn-on of the signal. | |||

Calculations
- At 10,000 rpm, each rotation takes 6 ms. If we have 10 magnets, then we have 0.6 ms over which to control the on-off of magnets. Since we need to divide that at least by 10, and more like 100 - so we need to have about 6-60 microsecond control over the turn-on of the signal.
