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 .

Features:

Circuit power supply obtained from AC net

Can be used in with AC networks 220 V / 50 Hz and 110

V / 60 Hz

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).
