Also test shadows.For instance, there's all the time two moneybags beneath the far finish of this bridge, but one (magenta) is invisible. If we've got two otherwise identical motors, one with a low Kv and one with a high Kv, then we can assume that the average magnetic discipline produced by the rotor magnets and the dimensions of the rotor itself (i.e. its radius and length) are the identical. The motor with fewer turns of wire could have a decrease induced voltage produced by the rotor magnets as they move by the tooth, giving it its high Kv rating when in comparison with the motor with extra turns.

When you sum up the current contributions from every part for the sinusoidal waveform (PMSM) and for the trapezoidal waveform (BLDC) you see the same end result; a perfect constant output present, and therefore a continuing output torque. Most low-cost passion grade motor controllers (ESC's) solely output a 'six-step a hundred and twenty degree' current waveform like that proven for the BLDC motor above.
