    PWM dc motor speed control

    Hi FvM, input voltage, Current have little tolerance over torque for DC motors . you can't change much to get same torque in any speed. yes, if you use kind of tacho gen or encoder you can make close loop controller and watch the load(constant torque )and Keep the speed, but this can do only...

    PWM dc motor speed control

    low torque in low speed is inevitable for dc motors , if need constant torque need to use gear system with high side speed controlling.

    what is the advantage of semaphore over use of global flag

    Hi all I think this question may already arose, but didn't see a good answer. so i thought to start new thread. My problem is what is the advantage of use semaphore over global flag ? this is the situation. in my system two tasks use single RS232 out FIFO to send data. if any one task...

    introduction to magnetic ink character recognition

    thank you amitjagtap and ckshivaram, but i'm looking for more technical document. i want to know the technologi behind Magnetic ink characters like CMC7 and E-13B recognition. i now there is magnetic field and there is sensor which can identify magnetic feild variation. but i want more...

    how do i change foot print at once in orcad layout9.2

    hi i use orcad layout 9.2 for pcb work. can any one show me a way to change the existing foot print associated with particular parts at one. i mean let say i want to change the foot print of all resistors in my design at once. i don't want to change one by one. thank you

    PhD, related to electronic engineering discipline

    yup it's scholarship for mobility, yup i have to ask from them. but before i going to further i have to verify any one out there went on this path before, i mean Bs in physics Ms in applied electronics PhD in EE or similar path wasting time for non-realistic thing is not tolerable when concern...

    PhD, related to electronic engineering discipline

    i don't think they award twice for a single applicant. isn't it? :?: i got that scholarship for my masters degree.

    PhD, related to electronic engineering discipline

    thank you for your advice joydeepsarkar87. i got to know that universities in USA are more concern on the type of bachelor degree while in European university much concern on the subject which were followed thro' out our bachelor and masters studies. am i right?
