    摘要： A load torque estimation apparatus estimates load torque of an electric motor. The apparatus includes an estimation part configured to input a controlling value for controlling the electric motor and an actually measured value of a rotational speed of the electric motor to a model and estimating load torque of the electric motor; and a derivation part configured to derive a mechanical time constant of the electric motor corresponding to the actually measured value of the rotational speed of the electric motor. The estimation part is configured to update, according to a timing of acquiring the actually measured value of the rotational speed of the electric motor, the mechanical time constant included in the model by using the mechanical time constant corresponding to the acquired actually measured value and estimate the load torque of the electric motor by using the updated model.

    摘要： A load torque estimation apparatus inputs a controlling value for controlling the electric motor and an actually measured value of a rotational speed of the electric motor to a model to estimate load torque of the electric motor; and derives a mechanical time constant of the electric motor corresponding to the load torque estimated by the estimation part. The load torque estimation apparatus updates the mechanical time constant included in the model by using the mechanical time constant corresponding to the load torque estimated at an (n−1)th control period (where n denotes an integer greater than or equal to 2) and estimates the load torque of the electric motor at an nth control period by inputting the controlling value and the actually measured value acquired at the nth control period to the model acquired through the updating.

    摘要： A motor control apparatus controls a start/stop operation of a motor and includes a counting unit that performs a count-up or count-down operation from a predetermined initial value with a lapse of time in response to receiving an operation start instruction for the motor; a signal output unit that outputs a first state signal in response to receiving the operation start instruction, and outputs a second state signal only when a result of the counting by the counting unit falls outside a predetermined range; and a drive unit that outputs an ON signal to the motor in response to receiving the first state signal from the signal output unit, and outputs an OFF signal to the motor in response to receiving the second state signal from the signal output unit.
