Patent ID: 8228018

Claim:
A motor control system, comprising: (a) a motor unit including: (i) a motor; (ii) a resolver configured to detect a rotational angle of said motor; and (iii) a first memory configured to store first error data for detection by said resolver of the rotational angle of said motor; and (b) a controller unit configured to electrically connect with said motor unit, said controller unit including: (iv) a second memory configured to store second error data for detection by said resolver of the rotational angle of said motor; and (v) a motor controller configured to control rotation of said motor, said motor controller configured to determine an actual rotational angle of said motor in accordance with the detected rotational angle detected by said resolver and said second error data stored in said second memory, and said motor controller configured to control rotation of said motor in accordance with the determined actual rotational angle, wherein one of said motor unit and said controller unit further includes: (vi) an update section configured to update said second error data stored in said second memory with said first error data stored in said first memory in accordance with motor data stored in said first memory and motor data stored in said second memory.
