I doubt the claim that printing a coil on PCB is cheaper than winding wire coils. At any rate you have to print the design on PCB , etch it join those double side PCBS. It cannot be cheaper.
- iamleppert 8y agoYou can build a coil winding jig to automate the winding process too..
- pankajdoharey 8y agoYup absolutely, plus the amount of conductor you can use is limited on a PCB. It is cool but not cheaper.
- metaphor 8y agoWhen IEEE claims cheaper, they certainly don't mean in terms of Joe basement hobbyist complementing his next Arduino weekend hack. At production scale--starting in the low 100s by rough estimate--and presuming motor specs satisfy application requirements, cost per unit would quickly approach rock bottom.
- leoedin 8y agoPCBs are super cheap. If you design one which is of a common type - 2 or 4 layer, FR4, 1.6mm etc, the price per unit is very low. There's lots of Chinese board houses now that will produce 100x100mm boards for 50c a board if you buy 10! That's $5 including postage to have a double sided PCB made. 4 layer is slightly more expensive at lower quantities, but once you get more than a few hundred made you're looking at under $1 a board. If you want to make a product cheaply, doing it in a way that makes use of the electronics production process is a really good way to start. Compared to implementing your own mechanical designs and manufacturing process it's really, really easy and cheap.
