MOTOR DRIVING APPARATUS

摘要

A motor driving apparatus includes a boosting section, a drive voltage output section, a detecting section, a storage section and a determining section. The boosting section generates a post-boosting voltage by boosting an input voltage. The drive voltage output section generates a drive voltage to drive a motor using the post-boosting voltage. The detecting section detects a value of the input voltage or a variation width relative to a reference value of the input voltage as variation power source variation information when there is power source variation. The storage section stores target value association information associating the power source variation information and a boosting target value of the post-boosting voltage. The determining section determines the boosting target value based on the power source variation information and target value association information. The target value association information is determined based on a range of operations of the drive voltage output section.
