Title:
駆動装置、流体利用装置及び空気調和機
Document Type and Number:
Japanese Patent JP6877592
Kind Code:
B2
Abstract:
A drive system (100) includes a current detection unit (4a) that detects a current flowing to a main synchronous motor (1a), and a current detection unit (4b) that detects a current flowing to a secondary synchronous motor (1b). The drive system (100) includes a magnetic pole position estimation unit (5a) that estimates the magnetic pole position of the rotor of the main synchronous motor (1a), and a magnetic pole position estimation unit (5b) that estimates the magnetic pole position of the rotor of the secondary synchronous motor (1b). The drive system (100) includes a current control unit (6) that outputs a voltage command, and a secondary torque current pulsating component extraction unit (7) that extracts a pulsating component. The drive system (100) includes a subtracter (8) that determines an angle difference, and a magnetic flux current command determination unit (9) that determines a magnetic flux current command.
