Title:
MOTOR DRIVE CONTROL DEVICE, MOTOR DRIVE DEVICE, AND ELECTRIC VEHICLE HAVING SAID MOTOR DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/065545
Kind Code:
A1
Abstract:
Provided is a motor drive control device capable of reducing the number of components, costs, and space and weight. This motor drive control device (22) is a motor drive control device for controlling motor equipment (MS) in which a plurality of systems of electrodes of the phases of a U-phase, a V-phase and a W-phase are provided in a plurality of three-phase motors (61), (62). This motor drive control device has: current sensors for detecting the currents flowing in the phases of the U-phase, V-phase, and W-phase of each system; and a motor drive control unit (19) which separately controls each system on the basis of the currents detected by the current sensors. At least one current sensor among the current sensors for detecting the currents of the three phases of each system is a contactless current sensor for commonly detecting the current of one phase in each of two systems, and the remaining phase current sensors are current sensors for performing detection separately.
