Brushless motor controller est adoptatus in control generis inverter, est aliud ex generali inverter. Adjust suum output frequency est non independens, sed per installed in hastili in synchronum motricium rotor situ detector imperium. Whenever the rotor turns a certain position (For example, 90 ° or 120 ° electrical Angle), the position detector to produce the corresponding signal, applied to the corresponding semiconductor components, make the corresponding phase winding electricity, torque is produced. Motricium Rotor per se rursus par vectes, semiconductor cogitationes in vices conduction week, inverter output ac mutatio secundum cycle. Ita auto-control generis inverter output frequency et gyratorium celeritatem motricium semper in sync, ibi non ex gradum. In Brushless motor controller, inverter est de transistor. Quia transistor habet facultatem ad averte, ut dum eius basis in potestate signo evanescit, et transistor et excludit per se, ita est facilius ad imperium. In magna capacitatem de Brushless DC motricium moderatoris, inverter ex composito ex thyristor. Thyristor non facultatem averte, potest removere trigger signum ut clauditur. So when current brushless motor controller need to stop, let another common electricity, how to shut off the original pilot of thyristor, the electric current is transferred to a new phase of thyristor, namely the thyristor converter between the problem is the key technique of thyristor motor controller.
