Hi,
i'm designing a very low quantity and low cost device from thin sheet metal, and i need to give the flat sides some rigidity. i've seen in stamped parts a designer can bend/press ribs, small folds, or other small impressions to give the metal some third dimension for rigidity... but if im...
yup... once a day. an average user would only use this device for 3 mins (average) per day each day for the 5 year life of product.
thanks for the electrical hints towards control schemes... i wont be doing the design myself; we will contract that. i simply wanted to research relative...
aaahh... yes i should look up these electrical terms before i ask dumb questions. thanks keith and wikipedia.
so off 'topic', but to control a DC motor closed loop to 10% accuracy do i need an encoder or can it be done with back EMF?

wow skogsgurra... i wasnt expecting someone to go so far as even recommend a part number- thanks! and yes, that indeed looks well suited. now if the bosch website would just cooperate and give me a US distributor! ha
can your H-brige control solution meet the 10% speed accuracy needed?
thanks...
Good points... sorry, some things I take for granted as I am around these projects everyday. The device could most easily be compared to a kitchen blender in size and useage, however unlike the blender, noise must be kept to a minimum. Efficiency is not a concern. Annual volumes are below 100...
We are planning a benchtop laboratory product which turns a special processing device for grinding and homogenizing various tissues and plant matter. I am doing research to find the best type of motor to do the job. My experience is with direct-drive brushless motors and gearhead DC motors, but...
