Document Type and Number:
WIPO Patent Application WO/2016/143534
Kind Code:
A1
Abstract:
A drive control unit, which is configured with redundant motor drive control systems so that a motor having two winding groups can be controlled for each winding group to be individually driven, has: an inverter substrate on which are formed a first inverter circuit for driving each winding of the first winding group, and a second inverter circuit for driving each winding of the second winding group; a control substrate (20) on which are formed a first control circuit (20A) including a microcomputer for controlling the first inverter circuit, and a second control circuit (20B) including a microcomputer for controlling the second inverter circuit; and a housing inside which the inverter substrate and the control substrate (20) are arranged side-by-side. The first control circuit (20A) is situated on the front surface side of the control substrate (20), and the second control circuit (20B) is situated on the back surface side.
