VARIABLE MAGNETOMOTIVE FORCE ROTARY ELECTRIC MACHINE AND CONTROL DEVICE FOR VARIABLE MAGNETOMOTIVE FORCE ROTARY ELECTRIC MACHINE

摘要

A rotary electric machine includes a stator (3) and a rotor (2). The rotor (2) has at least one permanent magnet (4) arranged in a d-axis magnetic path. The rotor (2) includes a magnetic gap part (12) located between the permanent magnet (4) arranged in the d-axis magnetic path of one pole and an adjacent magnet with a different polarity, such that a d- axis magnetic flux forms a d-axis bypass passing (10, 11) through an area other than the permanent magnet (4). The d-axis bypass (10, 11) provides a magnetic resistance in a d- axis direction that is set below a magnetic resistance in a q-axis direction that is orthogonal to the d-axis resistance.
