Title:
MOTOR DRIVING CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019062623
Kind Code:
A
Abstract:
To provide a motor driving control device in which the number of components can be reduced, and the cost reduction and space and weight reduction can be achieved.SOLUTION: A motor driving control device 22 controls motor equipment Ms provided with a plurality of electrode systems of three phases including a U phase, a V phase, and a W phase, across multiple three-phase motors 6and 6. The motor driving control device includes current sensors that detect currents flowing through the U phase, the V phase, and the W phase of each of the systems, and a motor driving control unit 19 that controls the systems separately by using the currents detected by the current sensors. Among the current sensors that detect currents of the three phases of each of the systems, at least one current sensor is a non-contact current sensor that detects currents of one phase of two systems together, while the current sensors of the other phases are current sensors that detect currents separately.SELECTED DRAWING: Figure 3
