<P>PROBLEM TO BE SOLVED: To provide a motor which is controlled in a sensor-less state with winding configuration of unbalance V connection. <P>SOLUTION: The V-connection motor whose phase voltages are unbalanced since inter-terminal impedance is unbalanced detects an inter-terminal voltage, a current Iy of a Y phase, and a current Iz of a Z phase, finds an induced voltage component of winding by calculating a voltage component of a self-inductance, a voltage component of mutual inductance, and a voltage drop component due to winding resistance, and detects a rotor rotational position θre from the induced voltage component to control the voltage and current. <P>COPYRIGHT: (C)2012,JPO&INPIT |
