    Abstract: 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).

    Abstract: PROBLEM TO BE SOLVED: To provide a control device of a brushless motor which can prevent malfunction in motor drive signal generation even when a rotor tremors while the motor is stopped and noise and the like are generated.SOLUTION: A sensor signal processing circuit 14 has two of three-phase magnetic pole position detection signals HU, HV, and HW of a brushless motor 20 detected by Hall ICs 24U, 24V, and 24W as input signals. When the two input signals repeat an H and L respectively, a first output signal sigA outputs a signal which repeats the H and L in response to the repetition of the H and L, and a second output signal sigB outputs a certain level of the H or L. When a first input signal repeats the H and L but a second input signal is at a certain level of the H or L, the first and second output signals output a certain level of the H or L.
