Title:
負荷駆動装置、空気調和機及び負荷駆動装置の運転方法
Document Type and Number:
Japanese Patent JP7170858
Kind Code:
B2
Abstract:
A load driving apparatus includes first and second motors (41, 42) that drive a plurality of loads on a one-to-one basis, and an inverter (4) that applies a common voltage to the first and second motors (41, 42). The first motor (41) is vector-controlled by a control unit (10). The second motor (42) is driven by the common voltage. The ratio of the winding resistance value of the second motor (42) to the winding resistance value of the first motor (41) as a reference motor is 2.4 or more.
