    • Permanent magnet housing spaces 3b and spaces 3c for flux barrier are formed within a rotor 3. A minimum value of a distance from a portion on a boundary face of the permanent magnet housing space in a rotor surface side which portion corresponds to an edge section of a permanent magnet 4 in its width direction to boundary faces of the both spaces in a rotation shaft side of the rotor 3 is determined to be greater than a distance of the permanent magnet housing space 3b in the thickness direction at an edge section of the permanent magnet 4 in its width direction, so that initial performance is maintained by preventing demagnetization of the permanent magnet due to a negative magnetic field from occurring. Thus a decrease in the cost of a brushless DC motor is realized by decreasing the volume of the permanent magnet.

    • A phase locked loop (PLL) circuit automatically corrects the offset of the analog (especially active type) loop filter to improve the stability and precision of the locked clock or frequency signals. In addition to the general PLL circuit configuration having active type loop filter (30), the PLL circuit also has a frequency comparing circuit (42), a DAC controller (44) and a DAC (digital-to-analog converter) (46). In an offset measurement mode, the outputs of phase error detecting circuit (12, 14) and frequency error detecting circuit (18, 20) are cut, respectively, to establish locking in offset measurement locked loop (42, 44, 45, 30, 40). In this case, offset correction code (EDs) are identified and held. In normal mode, DAC controller (44) has offset correction code (ED) input to DAC (46), and DAC (46) sends offset correction signal (EAs) to loop filter (30).
