hi My name is Afrasiab and i am new at this forum.

I am looking for a dc motor drive or DC chopper circuit which i can use to control DC voltage for a 1.1 KW motor. The motor is a separately excited DC motor. the rating for motor is 160v/9amps for armature and 190v/.74 amps for field..... I am attaching a diagram which i made on protues.....


I need to know will this circuit work and specially the rating and the component number of the MOSFET .


If any one has any other better circuit they r also welcome to help....


regards
afrasiab
