Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/097627
Kind Code:
A1
Abstract:
A UVW phase inverter control circuit (110) has a control function for generating inverter control signals (S1) for UVW phases, and an XYZ phase inverter control circuit (120) has a control function for generating inverter control signals (S2) for XYZ phases. The control function of the UVW phase inverter control circuit (110) is stopped during the execution of a BIST. A phase conversion unit (161) generates inverter control signals (S1#) for the UVW phases by performing phase conversion on the control signals (S2) from the XYZ phase inverter control circuit (120). When the UVW phase inverter control circuit (110) executes the BIST, a selector (171) outputs the inverter control signals (S1#) from the phase conversion unit (161) as the inverter control signals for the UVW phases and a selector (172) outputs the inverter control signals (S2) from the XYZ phase inverter control circuit (120) as the inverter control signals for the XYZ phases.
