dc motor drive using IGBT 220v 6 amps with interface facility display rpm
 

Dear jayarajankb
Hi
What do you want to do accurately ? design a DC motor controller with IGBT and PWM method ? if yes , do you want that the rotation polarity of your motor can change ?

dear Goldsmith sorry being late.
not require to change rotation of polarity.
basically I am, electronics service tech .now my service field is treadmill repair. I am fed up being non availability of specific components and related software for display unit of treadmill.So I want to try simple method for the same.
thanks for your kind attention on this thread.
thanks a lot..............................jayarajankb
 

Again Hi
Do you need any feed back from RPM ?
If yes , no problem , but if no , your circuit will be pretty simple .

Goldsmith
 

dear GOLDSMITH
feedback is a must................................................................in this tread and also in the life.
thanks jayarajankb
 

Well . you should design it with a microcontroller and with some ways to feed back :
1- tako generator
2- encoder and rotary encoder methods .
3- opto counter .
4- .... etc .
At first you'll need a simple PWM that it's duty cycle can change from zero up to 100 percent ( approximately ) . this you'll be able to change the speed as you want .
And about feed back loop , the feed back , response will have effect on duty cycle . to stabilize the RPM.
Good luck
Goldsmith
 
do suggest a microcontroller for the purpose
