| titleOfInvention | A phase estimator for synchronous reluctance motors. |
| abstract | PROBLEM TO BE SOLVED: To provide a phase estimating apparatus for sensorless vector control of a synchronous reluctance motor, and in particular, to provide a phase estimating apparatus which does not generate a phase error in principle. [Solution] First, the 2 × 2 stable filter 10a-1 showing a phase displacement of π / 2 [rad] at a frequency corresponding to the electric speed of the electric motor filters a differential value of a mirror magnetic flux having a mirror relationship with the stator current. After that, the phase estimating apparatus 10a is configured so as to extract and determine the rotor phase from the processed signal by the phase determiner 10-a2 using the mirror phase characteristic, thereby solving the problem.
