モータ制御装置及び空気調和機

Document Type and Number:

Japanese Patent JP6714154

Kind Code:

B2

Abstract:

A motor control device (100) includes an inverter (4) configured by a plurality of arms (4a), a smoothing means (3) supplying a direct-current voltage to the inverter (4), a shunt resistor (7_u, 7_v, 7_w) inserted between a lower-arm switching element for each phase of the inverter (4) and a negative-electrode side of the smoothing means (3), a master motor current sensor (9) outputting a voltage according to a current flowing in a first motor (51) connected in parallel to the inverter (4), and a computing unit (6) generating driving signals for a plurality of switching elements based on an output of the master motor current sensor (9) and an output corresponding to a voltage drop on the shunt resistor (7_u, 7_v, 7_w).
