To reduce labor for enabling anti-theft function.SOLUTION: This motor control device has: a first control part which controls a motor; a second control part which controls the first control part; and a start-up auxiliary part which detects that the motor is rotated by an external force in the state that electric power is not supplied to the second control part, and starts electric power supply to the second control part. The second control part attempts user authentication or waits for performance of the user authentication when electric power supply is started by the start-up auxiliary part or user instruction, and causes the first control part to perform at least either predetermined drive limit or predetermined brake when the user authentication fails or when the user authentication is not performed within a prescribed time after start-up.SELECTED DRAWING: Figure 4 【課題】盗難防止機能を有効化させる手間を削減する。【解決手段】本発明のモータ制御装置は、モータを制御する第１の制御部と、第１の制御部を制御する第２の制御部と、第２の制御部に対して電力供給がなされていない状態でモータが外力によって回転したことを検出して第２の制御部への電力供給を開始させる起動補助部とを有する。そして、この第２の制御部は、起動補助部又はユーザ指示によって電力供給が開始されるとユーザ認証を試み又は当該ユーザ認証の実施を待機し、当該ユーザ認証が失敗した場合又は起動後所定時間内に当該ユーザ認証が行われない場合には、第１の制御部に、予め定められた駆動制限と予め定められた制動との少なくともいずれかを行わせるものである。【選択図】図４
