Motor Control Circuit of VFC320
The aboved picture is the motor control circuit composed of VFC320.Tachogenerator G outputs AC current which is correspondent to motor speed.VTl circuit converts it into the narrow negative pulse and trigger frequency/voltage converter VFC320.There are operational amplifiers in VFC320 chip and they are used as the integratorof the speed control loop. When integrator receives the input control voltage of the corresponding average current of equal and opposite direction and the single trigger pulse current added to frequency/voltage converter feedback loop reaches balanced condition.DRVlO1 driver is used in motor and its maximum output current is 1.9 A and which is enough to drive the ordinary motor.
