    摘要： A semiconductor light source lighting circuit is provided with: a switching regulator that generates a drive current of a semiconductor light source using a switching element; and a control circuit that controls ON/OFF of the switching element. The control circuit is provided with: a comparator that compares the drive current and a target value; a counter that counts a digital value in a count direction determined by a comparison result of the comparator; a digital-analog converter that converts the digital value into an analog signal; and a drive circuit that controls the ON/OFF of the switching element based on the analog signal. The counter counts the digital value at a speed determined by an ON/OFF cycle of the switching element.

    摘要： A semiconductor light source lighting circuit includes a switching regulator that produces a drive current ILED with a switching element, and a control circuit that controls turning on and off of the switching element so that the magnitude of the drive current ILED approaches a target value. The control circuit includes an error comparator that compares the drive current ILED and the target value, an up/down counter that performs a counting operation, in which the control digital value is incremented or decremented based on the result of the comparison, a D/A converter that converts the control digital value into an analog duty ratio setting signal S4, and a drive circuit that controls the turning on and off of the switching element based on the signal S4. The up/down counter stops the counting operation when the switching regulator is brought into the inactive state.

    摘要： A rotor slot is asymmetrically shaped with respect to a straight line drawn from the central axis of the rotation of the rotor in a radial direction, and has a slot opening, the circumferential width of which is smaller than that of the rotor slot, at the top of the rotor slot, so that a loss generated in the rotor due to a carrier harmonic component can be reduced and the power factor can be improved, enabling a current generated in an armature winding to be suppressed and thereby improving efficiency in a rated operation.

    摘要： A sensor magnet holder is mounted on a motor shaft, and a sensor magnet is provided relative to a magnetic induction sensor on the non-moving side for obtaining a signal indicative of a rotational position of the motor shaft. The sensor magnet holder integrally forms a cylindrical portion, a flange portion of a terminal end of the cylindrical portion having a large diameter, a magnet rear end holding portion of the other terminal end of the cylindrical portion and a plurality of snap fit board portions. A shaft press fit portion is formed on an internal diameter of the flange portion. The plural snap fit board portions extend from the cylindrical portion in an axial direction of the motor shaft. A magnet front end holding portion is formed at an extending tip over an outer diameter surface of each of the snap fit board portions. Each of the flexible snap fit board portions snuggly contacts the inner flat surface of the sensor magnet while the sensor magnet is held between said magnet rear end holding portion and said magnet front end holding portion.
