Abstract

A motor controller is configured to perform positioning of a rotor of a brushless motor immediately when power supply is turned on, and not after actually receiving a target value related to control for the brushless motor from a main ECU, which determines the target value. The motor controller finishes or is performing the rotor positioning, when the target value is received from the main ECU. For this reason, the motor controller can start rotation control for the brushless motor in accordance with the received target value in a short period of time.

First claim

What is claimed is:

1. A control system for a brushless motor having a rotor made of a permanent magnet set and a stator coil set of plural phase coils, the control system comprising:
a main ECU configured to determine a target value related to control for the brushless motor;
a position detection section configured to detect a rotation position of the rotor; and
a motor controller configured to perform rotor positioning processing for the rotor by supplying a current to a spe…
