Title:
MAGNETIC POLE POSITION DETECTION DEVICE FOR SYNCHRONOUS MACHINE
Document Type and Number:
WIPO Patent Application WO/2011/162011
Kind Code:
A1
Abstract:
Disclosed is a magnetic pole position detection device which is for a synchronous machine and which can obtain a desired accuracy of magnetic pole position detection regardless of fluctuations in the DC voltage of a DC voltage source. In order that a desired accuracy of magnetic pole position detection can be obtained regardless of fluctuations in the DC voltage of a DC voltage source (5), a calculation means (2a) alters a pulse suspension width (tn) and a pulse width (tp) by means of a pulse width determination unit (22a) and according to a detected DC voltage value (Vdc), and controls such that a sampling timing is fixed to the pulse width (tp) termination point of each voltage vector, regardless of the detected DC voltage value (Vdc).
