    • Provided are a brushless motor control device (3) and a brushless motor system capable of preventing impossibility of intended control of a brushless motor (4) resulting from false recognition that the brushless motor (4) is in operation in spite of stoppage of the brushless motor (4). A brushless motor control unit (302) calculates a voltage instruction, representing voltages to be applied to the brushless motor (4), according to a control instruction supplied from an upper control device (12). A position error calculation unit (306) calculates and estimates a position error between d-q-axes and dc-qc-axes as rotational coordinate axes by use of the voltage instruction outputted by the brushless motor control unit (302), current values acquired by a coordinate transformation unit (305) and revolution speed for control of the brushless motor (4). A fault detection unit (308) judges whether the brushless motor (4) is faulty or not based on the position error calculated by the position error calculation unit (306).

    • A motor control system suppresses vibration of a machine base and achieves high-speed positioning without using a special sensor but using a model control system. A first feedback section outputs a first feedback command generated based on model machine base position information and containing at least position information on the machine base. A second feedback section outputs a second feedback command containing a filtered model torque command. A differential between the sum of the first feedback command and the second feedback command obtained by a second addition section and the model torque command is calculated to give the differential to an input portion of a model torque command low-pass filter and an input portion of a torque command low-pass filter. The model control system gives a model position command to a position controller as a position command, and model machine base position information generated based on the model position command is added to a speed command input from the position controller to a speed controller.
