Magnetic pole detection system and magnetic pole detection method
摘要:
A magnetic sensor array including a plurality of magnetic sensors detects a phase regarding a magnetic pole of a magnetic pole array including magnetic poles of N and S arranged alternately. A pitch identification unit detects a pitch number of the magnetic pole currently being detected by the magnetic sensor array, in the magnetic pole array.
