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 and a rotor. The rotor has at least one permanent magnet arranged in a d-axis magnetic path. The rotor includes a magnetic gap part located between the permanent magnet 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 through an area other than the permanent magnet. The d-axis bypass 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. |
