摘要
A magnetic pole position detecting device for a synchronous motor includes: a storage unit for storing a reference magnetic pole position of the synchronous motor as a predetermined reference; a magnetic pole position detector for detecting the magnetic pole position of the synchronous motor when a predetermined condition is satisfied; and a determination unit for comparing the reference magnetic pole position stored in the storage unit with the magnetic pole position detected by the magnetic pole position detector to determine that detection of the magnetic pole position is abnormal when the difference between the two falls out of a predetermined range.
