摘要： A controller for a permanent magnet synchronous motor having a rotor using a permanent magnet is provided. The rotor rotates by a rotating magnetic field caused by a current flowing through an armature. The controller starts a deceleration control of reducing a rotational speed of the rotor when a stop command is inputted in a state where the rotor rotates at a predetermined rotational speed; and performs a fixed excitation control when the rotational speed is reduced to a set speed. The fixed excitation control includes setting a current for causing a magnetic field vector for stopping the rotor at a target position in accordance with an amount of rotation of the rotor since the deceleration control has started and passing the current through the armature.

摘要： A charge control device uses external electricity to charge a plurality of battery devices. A constant current source uses the external electricity to generate and adjust an output current amount to a constant target value. A selector selects one battery device from the plurality of battery devices and supplies output current from the constant current source to the one battery device. A measurer measures an amount of actual current flowing from the constant current source to the one battery device. An instructor monitors a measured value provided by the measurer and instructs the selector, when the measured value meets a condition for a reduction of charging current amount to be regarded as having occurred, to change a destination to which the output current of the constant current source is supplied from the one battery device to a different battery device.

摘要： The image forming device includes a reception unit, an image forming unit, a switching unit, a detection unit, and a charging unit. The switching unit switches the image forming device between a first mode in which the reception unit is not supplied a voltage from a power source, is supplied power from a secondary battery, and receives image forming requests, and a second mode in which the image forming unit is supplied the voltage and performs image forming. The detection unit detects a value of an amount of energy of the secondary battery. In the second mode, the charging unit charges the secondary battery by supplying the voltage to the secondary battery when the value is equal to or less than a threshold value, and the charging unit boosts the voltage and supplies the boosted voltage to the secondary battery when the value is greater than the threshold value.
