Control system for motor

摘要

A control system (1) for a motor includes: a motor unit (2) including a motor (21) and a resolver (22) configured to detect a rotation angle of the motor; and controlling means (3) for determining an actual angle from the detected angle detected by the resolver using error data (24) representing an error between the detected angle of the resolver and the actual angle, and controlling rotation (31) of the motor on a basis of the determined actual angle, the controlling means being electrically connected in a replaceable state to the motor unit; wherein the motor unit includes a motor side memory (23) configured to store the error data (24) in advance, the controlling means includes a controlling side memory (35) configured to store the error data used when the actual angle is determined, and one of the motor unit and the controlling means includes capture determining and performing sections to transfer the error data from the motor side memory to the controlling side memory, e.g. upon powering up the control system.
