Motor control project

I have a project on designing a motor control circuit using H- Bridge. the switching devices employed can be mosfets, bJT, thyristor or IGBT. can nyone run me through which 2 possibilities are the best. the motor used is a 12v brushed motor with 6.6ohms resistance and 0.445mH inductance. the back emf is 8.6v.

How about a pic micro (16F88) generating a pwm signal, driving a H bridge, sample the back emf of the motor using one of the pic's adcs?...

H bridge comprises of two pairs of complementary mosfets in the usual configuration.

Each of them has its pros and cons. The latest motor drivers are using IGBT.

Check out this data sheet, especially the schematic at the bottom:

This product uses a 16F88 PIC processor to control either the ULN2803 Darlington array IC, the L293 half-bridge IC, or four 9Amp/24V FETs to drive DC motors. Read the specs, determine which part does the job best for your application, then copy it.
Have a nice project.
