DC motricium moderatoris in usu, in satus frequency non esse nimis altum. Quia eius celeritate est nullus cum iustus incipiens, electro torque in processus incipiens superare onus resistentia Aureus et vincere in masking inertiae rotating parte, ita DC motricium, ut assumtur maius quam cum continua operationem. At startup time, if the pulse frequency is too high, so will lead to the rotor speed to keep up with the speed of the stator rotating magnetic field, after that, each step in the rotor speed increase is not much, but still to is proportional to the stator magnetic field of pulse frequency speed rotation, the rotor and the distance between the equilibrium position is more and more big, so that the motor controller can not start properly, will damage the motor controller.
