<P>PROBLEM TO BE SOLVED: To provide a motor controller generating torque just as a torque command without using a voltage detector for a voltage model flux operating unit or a temperature detector for estimating the magnet temperature of a motor; and to provide a method for correcting the induced voltage constant. <P>SOLUTION: A q-axis current control section comprises: a q-axis current proportional control section (132) generating a first q-axis voltage command; a q-axis current integration control section (133) generating a second q-axis voltage command; an induced voltage compensation section (135) generating a third q-axis voltage command by multiplying a motor speed by a second coefficient K2; q-axis voltage command generating/adding sections (134, 136) generating a q-axis voltage command by adding the first q-axis voltage command, the second q-axis voltage command, and the third q-axis voltage command; and an induced voltage constant correction section (137) generating an induced voltage measurement Kee based on the second q-axis voltage command. <P>COPYRIGHT: (C)2009,JPO&INPIT |
