コンデンサモータ駆動回路ＶＣ係り、特にコンデンサモ
タ駆動中の電磁音の発生防止に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a single-phase capacitor motor drive circuit VC for an air conditioner having a number of taps for wind cutters, and in particular to the generation of electromagnetic noise while driving the capacitor motor. Regarding prevention.

なかった。In the conventional device, as described in Japanese Patent Laid-Open No. 55-118550, only one capacitor was provided because it focused only on driving a capacitor motor for a plurality of VC taps. However, no consideration was given to the breakthrough magnetic field of each tap.

。The above conventional technology does not take into account the optimum magnetic field for each tap of the capacitor motor, and the capacitor motor is usually designed so that the resistance value of the tap is minimized and the motor efficiency is maximized. For this reason, while the resistance value increases in other taps, the inserted capacitor capacity remains constant, so the distortion of the motor magnetic field increases, and the phase difference between the auxiliary winding current and the main winding current becomes large at light loads. and becomes smaller during overload, and in both cases, the reactive current value increases and pot harmonics of twice or four times the power frequency are likely to occur, so these distortion energies are generated as electromagnetic sound. There was a problem.
本発明の目的は、この電磁音の発生を防止することにあ

さくなる。A capacitor motor having a plurality of taps has a motor driving coil between the common tap and other taps, and when a voltage Vc is applied to the I side of the coil, a current flows and a magnetic field is generated. Similarly, a magnetic field is generated in the auxiliary coil section provided for driving. For condenser motors for air conditioner blowers,
Normally, the magnetic field of the tap with the minimum resistance value is close to a perfect circle, that is, the phase difference between the auxiliary winding current and the main winding current is 90°.
The capacitor capacity is often determined as well. However, in other taps, the resistance value increases and the capacitor capacity required to create a perfect circular magnetic field increases, but on the other hand, the inserted capacitor capacity is constant, so the magnetic field is distorted. This tendency becomes more pronounced as the difference between the capacitor capacity and the coil resistance increases. Therefore, by inserting a capacitor for each tap or only for the tap with the largest difference from the capacitor capacitance setting coil resistance, the magnetic field becomes a perfect circle and the electromagnetic noise generated becomes extremely small.
