Description
本願に開示される誘導電動装置は、交流電源から入力された電力を全波整流する全波整流回路、前記全波整流回路に接続され、全波整流された電圧値を予め定められた直流成分によってオフセットするＤＣオフセット回路、および前記ＤＣオフセット回路に接続され前記ＤＣオフセット回路の出力電圧の周波数に基づいて運転される誘導電動機を備え、前記ＤＣオフセット回路が、抵抗、前記抵抗に直列接続されたスイッチ、および前記抵抗と前記スイッチとの直列の接続体を前記誘導電動機の主巻線および補助巻線に対して並列に接続するコンデンサを有し、前記スイッチによって全波整流された前記電圧値が最大となる電気角の時点に前記抵抗を導通させ、電圧値が最大となる前記時点から所定遅れの電気角の時点において前記抵抗を前記誘導電動機の前記主巻線および前記補助巻線から断線させるようにしたことを特徴とする。 The induction motor device disclosed in the present application includes a full-wave rectifier circuit that performs full-wave rectification of power input from an AC power source, and a full-wave rectifier connected to the full-wave rectifier circuit to convert the full-wave rectified voltage value into a predetermined DC component. and an induction motor connected to the DC offset circuit and operated based on the frequency of the output voltage of the DC offset circuit , the DC offset circuit comprising a resistor connected in series with the resistor. a switch, and a capacitor that connects a series connection body of the resistor and the switch in parallel to a main winding and an auxiliary winding of the induction motor, and the voltage value full-wave rectified by the switch is The resistor is made conductive at the time of the maximum electrical angle, and the resistor is disconnected from the main winding and the auxiliary winding of the induction motor at the time of the electrical angle that is a predetermined delay from the time when the voltage value becomes the maximum. It is characterized by the following .
位相が８０付近（接続端子ｐ３‐ｐ４間の電圧の最大値付近）でスイッチング電源がオンすると、スイッチ５０がＡ側に接続され、ＤＣオフセット回路２０の抵抗２１に電流が流れる。次に位相が２１０付近でスイッチング電源がオフすると、スイッチ５０がＢ側に切り替えられ、ＤＣオフセット回路２０の抵抗２１に電流が流れなくなる。なお、主巻線３１と補助巻線３２には常に電流が流れている。つまり、スイッチ５０をこのように切り替えることによって、ＤＣオフセット回路２０の抵抗２１に流れる電流を減らすことによって、誘導電動装置６００の消費電力を抑制できる。
When the switching power supply is turned on when the phase is around 80 (near the maximum value of the voltage between the connection terminals p3 and p4 ), the switch 50 is connected to the A side, and current flows through the resistor 21 of the DC offset circuit 20. Next, when the switching power supply is turned off when the phase is around 210, the switch 50 is switched to the B side, and no current flows through the resistor 21 of the DC offset circuit 20. Note that current always flows through the main winding 31 and the auxiliary winding 32. That is, by switching the switch 50 in this manner, the current flowing through the resistor 21 of the DC offset circuit 20 can be reduced, thereby suppressing the power consumption of the induction motor device 600.
