Title:
MOTOR DRIVE CONTROL DEVICE, MOTOR CONTROL CIRCUIT, AND MOTOR DRIVE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/243389
Kind Code:
A1
Abstract:
This motor drive control device measures the performance affecting parameters of a motor while taking the currents of two-phase coils, although having a simple circuit configuration. A control circuit unit (4) of a motor drive control device (1) performs control calculation processing of a motor (20) in a half-cycle of each of continuous two PWM cycles and obtains, in the remaining two half-cycles in which the control calculation processing in the continuous two PWM cycles is not performed, a first current detection result and a second current detection result that are the currents of the two-phase coils of three-phase coils obtained from a current detection circuit (2c) and a performance affecting parameter detection result obtained from a performance affecting parameter detection unit.
