子電動機の電流制御回路。Phase control is performed by inputting the speed control signal and main circuit current detection signal of a commutatorless motor driven by a forward converter that obtains AC power and converts it to DC, and an inverse converter that converts the output of the forward converter to AC. In a current control circuit for a non-commutator motor that intermittently controls the DC output current of the forward converter through a circuit, the time required for the main circuit current detection signal to rise from a control signal that intermittently controls the output of the forward converter. A setting device that generates a pulse signal having a width, and a sample-hold device that holds the main circuit current detection signal for a period of the pulse width of the output of the setting device are provided, and the sample-and-hold □ type output is obtained as a current detection value. A current control circuit for a commutatorless motor, characterized in that:
