Title: Inductance measuring method of pm motor
Inventor: YAMAMOTO YASUHIRO
IPC: H02P27/06
Filed: 2008-03-24
Abstract: <P>PROBLEM TO BE SOLVED: To solve the following problem: it is difficult to measure inductance due to initial set value in measuring a current response, and adjusting and converging a gain, in a system for driving a synchronous machine using a permanent magnet with an inverse transform circuit.  <P>SOLUTION: Each voltage command when supplying DC currents having high and low levels to a current control portion is respectively stored. Motor winding resistance is calculated by subtracting a difference in DC value between the two levels and a difference in voltage value between the two levels of the DC currents. Then the voltage value based on the larger current level of DC currents is rapidly changed to the voltage value based on the smaller current level of the DC currents, and the time when the current change reaches a predetermined value of a current step width at two levels is measured. The measurement value of winding resistance is subtracted from the measurement time to calculate d-axis inductance.  <P>COPYRIGHT: (C)2010,JPO&INPIT
