发明名称 MOTOR CONTROL DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a motor control device capable of reducing a shock due to increased torques, when switching from a PWM wave voltage drive to a square-wave voltage drive is performed. <P>SOLUTION: A switching between a PWM wave voltage drive and a rectangular-wave voltage drive is determined, based on the rotational frequency Nm and torque command value &tau;r of AC motor 4. When it is determined that this is switching from a PWM wave voltage drive to a square-wave voltage, the generated voltage value V of a generator 7 is lowered. When it is determined that the generated voltage value V is not greater than a predetermined voltage threshold Vref2, switching from a PWM wave voltage drive to a square-wave is performed. <P>COPYRIGHT: (C)2006,JPO&NCIPI
