IL9010N, IL9010D
IC of collector electric motor controller
Microcircuit is designed for stabilization of collector electric motor rotation speed. IC`s supply
power can be obtained from alternating current line with voltage 110 V or 220 V, frequency of 50
Hz or 60 Hz through half-wave rectifier and ballast resistor.
Functions:
Microcircuit enables stabilization of electric motor speed ,
optimal triac firing (2nd and 3rd quadrants ), repetitive trigger
pulses when triac current is interrapted by motor collector,
changing of triac current at work with induced load, soft start ,
power failure detection and general circuit reset .

Integration Cap
Stabilization of electric motor rotation speed is provided by integrated positive feedback on current.
IL9010N generates triac control pulses and provides stabilization of collector motor speed without tacho
generator.
Voltage comparator ensures control of basic circuit reset. While voltage levels coincidence, signal is
generating at comparator inputs (inputs 13, 14) and shifts control circuit from «Permitted» state to the
«Prohibited» state, in a similar way, as circuit state is changing while supply voltage low level. At that, circuit
becomes insensitive to the supply voltage variation (circuit of supply voltage variation control is blocked by
the signal from comparator output).
