hi i am doing project on to control no of machines that is switching control only. i wnt to control some motors to run at some time and some motors at some other time. can any body tell soft ware for this projct i am using 89c51 ic

Hi, I do realy need some think about the application of power electronics in elevator drives. thank you very much

it was ok but i still need the full circuit of the controlling unit

Please help me. I'm producing bolt, nut and fastener..I would like to design an Auto-checker machine, this auto-checker will cope with any replacement of mold within available distance of sensor or other change of environment through active tracking because the microcomputer IC operates with automatic set up so that it can grasp all machine conditions after its establishment and be suitable for machine fluidity(play) and sensor distance. Speed : one stroke 1200 times/min. two stroke 600 tyimes/min Available distance of sensor: 0.2-3.5mm after the replacement of mold with this available scope, any sensor distance does not need to readjustment. Dismantling capacity: 2/1000mm..

Thanks

I have an unusual question related to health problems and electromagnetic fields....due to fibromyalgia I have become very sensitive to emf. If I use a dialup connection for the internet, I do better than if I used a high speed dsl modem. Can you explain why that might happen? Does it makes the computer operate faster? Would a fiber optic connection be different than dsl? Many thanks!

may i use this circuit on 80 vdc
