INVERTER CIRCUIT FOR BIPOLAR-STARTING AND UNIPOLAR-RUNNING METHOD TO DRIVE A BRUSHLESS DC MOTOR

摘要

The present invention is more than a starting torque for starting and improved high-speed driving of the conventional brush-less DC motor, - relates to a new inverter for effectively implementing a single-phase drive method. ; When starting the use Sang - Gu gogidong Act to obtain a torque, and to use the single-phase driving method in order to obtain a high-speed driving at the same time it is necessary to control the current unexpected reflux caused by the single-phase counter-electromotive force when driving. ; Thus, using the new drive control is possible over the reflux current activation through the reflux current control can be obtained to improve the performance of the brush-less DC motor which meets the purpose of starting a single-phase method. ; Brie Siris DC motor, start over - single-phase drive method, a reflux current inverter
