[General] dc motor drive and control

[lovelyrain]

please am working on dc motor control and i winder if i can drive a dc motor efficiently with 5khz frequency off my pwm.

you can control the speed of a DC motor using PWM and 5KHz should be OK
however, speed is not linear vers PWM width as you have to overcome the resistance of the bearings + load etc but is OK for simple applications

for discussion of alternatives have a look at Microchip's motor control pages

thanks very much but wen i simulated the work on protus the motor was running too slow any idea on how i can trouble shoot dat

it could be because you are using a simulator
I always use real hardware myself
