To answer the original question -- for a 6 pole motor, maximum reasonable motor speeds are limited to around 42,000 RPM (25khz commutation frequency.) Above that, timing will start to fade towards neutral.

And you won't want to go any faster than that anyway -- magnetic losses would be terrible at those RPMs.
