| 摘要 |
A control apparatus for a reluctance type synchronous motor wherein slit-shaped gaps or a nonmagnetic material are included within a rotor to provide level differences of the magnetic reluctance in a rotating direction, and a permanent magnet is included at a portion of the slit-shaped gaps or the nonmagnetic material to provide magnetic polarities at a rotor surface. The control apparatus includes a q-axis current calculation unit, a d-axis current calculation unit, a speed coefficient calculation unit, a q-axis current compensation value calculation unit, and an output unit which outputs a compensated q-axis current command value in which the calculated q-axis current compensation value is added to the q-axis current command value.
