MOTOR CONTROL APPARATUS

摘要

A motor control apparatus controls a rotation of a motor based on a resolver signal that is output from a resolver and is in synchronization with a rotation angle of the motor. The motor control apparatus includes a control hardware block configured to correct the resolver signal; and a memory installed outside the control hardware block and configured to store error data of the resolver signal. The control hardware block includes an access part configured to read corresponding error data corresponding to a predetermined resolver rotation angle at which the resolver signal will be detected in the future from among the error data stored by the memory, a memory area configured to store the corresponding error data that is read by the access part, and a correction part configured to correct the detected resolver signal based on the corresponding error data stored in the data area.
