haay all
I'm trying to design a drive circuit to control a 1 hp, 24 V DC motor using PWM.
The rated current for this motor is 40 Amp.
Unfortunately, I could not find any transistors that could handle this current in my local electronic store.
I found the MJ15003 ( http://www.onsemi.com/pub_link/Collateral/MJ15003-D.PDF ) which can handle 20 Amp. So i tried to use 4 of them parallel (as in the image) ( http://imgur.com/AOugw ) . But the current passed through only one transistor and damaged it.
Anyone can suggest anything to help me with my problem
thanks
