ELECTRIC DRIVE AND METHOD FOR CONTROLLING IT |
摘要 |
<p>An electric drive (1) comprises: a permanent magnet brushless motor (2), a motor (2) power supply bridge (3), a circuit for controlling the power supply bridge (3) according to rotor position and phase currents (Is); the drive (1) comprises a circuit (6) for detecting the zero crossings of the induced counter electromotive force (Es) in the stator windings to determine the position of the rotor and a circuit (25) for indirectly detecting the amplitudes of the phase currents (Is).</p> |
