i have try the IRF series (IRF640 & 740), there are better for high speed switching in motor control.i dont know how many voltage & current of your motor control so u better check the data sheet of the power mosfet.always choose the larger voltage and current rating so that there will not easy get hot.also remember to add heat sinks.

hello

sorry for the untranslated email??? i was mis-sent to the groups...sorry....

now i want to ask

i want to control motor speed, i use atmega16, xtal 11.0592 MHz and timer1 for generate PWM....and transistor for switching.

1. which one is best timer1 configuration for motor control from OCR1???

2. which is better for switching transistor, TIP35 (BJT darlington) or IRF540 (MOSFET)????

 

please give me clue.....

regarding forwart to your reply soon
