I've been reading a couple threads where members discuss diecast and stamped steel. Unfortunately I don't know what the difference is. Could someone please explain  |

fans motor with cast iron is almost always thick, heavy and in many cases, powerful since most cast iron fans are old.. examples of cast iron motors include any union industrials, USHA airking (from 60s. not the current), USHA prima, USHA pulsar.. i am not sure whether the earliest lagunas were stamped or cast..
stamped iron fan motors always have a very thin layer of iron, when you hit it, you will hear some clear "ting" sound.. many of them could be from a cheap brand or in other words, new.. some old fans do have a stamped iron motors but they are powerful.. some stamped iron motors can be bent if applied enough force
there are some motors i have made from aluminum whether cast or stamp, such as crompton greaves and crompton parkinson and the inner motor case of the national and KDK.. there is a rare case where the entire motor is plastic such as relite fan and a model of pak fan
edit: some stamped iron motors resemble tuna cans in cheapness
