    Abstract: A disc rotor 10 has an annular sliding portion 11 and a hat portion 12 integrally provided at the inner periphery of the sliding portion 11. The sliding portion 11 has an annular braking portion 11a which is nipped between front and back friction pads 20 at the time of braking. A plurality of circular non-penetrating holes 11a2 are provided on front and back annular contact surfaces S of the braking portion 11a of the sliding portion 11 against which friction materials 21 of the corresponding brake pads 20 are pressed at the time of braking. The centers of the non-penetrating holes 11a2 are located at different positions in the rotor radial direction. The non-penetrating holes 11a2 are disposed at predetermined intervals in the rotor circumferential direction. Thus, it becomes possible to reduce the amount of wear of the friction materials 21 caused by the circular non-penetrating holes 11a2 (provided for restraining fading which occurs due to gas generated from the friction materials of the brake pads through thermal decomposition caused by friction heat at the time of braking).

    Abstract: A motor driving apparatus comprises: an AC/DC converter which converts AC voltage supplied from an AC power source into DC voltage through PWM switching control of a power switching device; and a DC/AC converter which converts the DC voltage into variable-frequency AC voltage for driving a motor in a controlled manner. The AC/DC converter includes: a control unit which generates, based on an error between the DC voltage and a DC voltage command value, a PWM signal for the PWM switching control of the power switching device; and a frequency/gain varying unit which sets the frequency of the PWM signal to be generated by the control unit and a control gain in the control unit higher than their normal levels during a period in which a load in the DC/AC converter varies.
