Abstract

PURPOSE:To reduce the higher harmonics of an armature current and decrease noises and vibration, by smoothly changing an applied voltage to the armature winding of the transistor motor while controlling the input current of Hall elements and the input DC voltage of an inverter to constant levels. CONSTITUTION:When the current corresponding to the inverter voltage V1 is caused to flow through the Hall elements 1-3, a voltage proportional to interlinked magnetic flux and to the inverter voltage V1 is generated as the output of the Hall elements. When the output voltage of the Hall elements is applied to a U-phase differential operational amplification circuit 10A, the potential Vu on the common collector of transistors Q3, Q4 takes a wave form Vus. If the inverter voltage V1 is as shown in (a), the output voltage Vu is saturated throughout an electric angle thetas determined by the ratio of resistances 25, 26. The electric angle thetas is controlled to be constant, the wave form remains fixed. A U-phase current Iu takes a wave form made by dividing a voltage (Vu-eu) (eu denotes an induced voltage) by a winding resistance, as shown in (b). The same thing goes as to a V-phase circuit and a W-phase circuit.
