  • Inverter unit
    Patent number: 8604732
    Abstract: The two-phase modulation control inverter unit includes a plurality of switching devices, a shunt resistor and a controller. The switching devices drive a three-phase motor. The shunt resistor is connected between a direct-current power supply and the switching devices. The controller reads a voltage applied to the shunt resistor in a read cycle, computes command voltages based on the read voltage, and uses the command voltages and carrier signals to compute three control signals. The read cycle corresponds to two or more signal cycles of each carrier signal. Each control signal has a pulse for each signal cycle of the corresponding carrier signal. The controller integrates a plurality of pulses of each control signal in the read cycle into one or more pulses. The controller reads a voltage applied to the shunt resistor at the time of outputting of the integrated one or more pulses in the next read cycle.

  • Stroke sensor and rotation angle sensor
    Patent number: 8368391
    Abstract: A stroke sensor has two magnets, which are magnetized in a cross-section direction and are displaced in a longitudinal direction, and two magnetism sensitive sections arranged parallel to the longitudinal direction. The magnets have circular-arc-shaped swelling end edges respectively and are magnetized such that the swelling end edges have opposite polarities. Thus, a distribution of a magnetic flux density on an arrangement axis substantially coincides with a sine curve. The magnetic flux having such the distribution is displaced in the longitudinal direction together with the magnets. The magnetism sensitive sections are arranged on the arrangement axis to be distant from each other by a distance of one fourth of a cycle of the sine curve. Thus, the stroke sensor that is not affected by temperature and that has high sensing accuracy can be provided.
