to calculate the weight copper
to calculate the weight copper
(OP)
Dear All,
if i have data for a motor :
number of coil ,turn/coil,pitch,AGD,CMA,stator core length,core diameter, connection,slots, wire size, is it possible for me to calculate the weight of copper for the wire from those data?by the way this is for low voltage motor
thank you,
regards,
Marten

RE: to calculate the weight copper
Total coper length is (number of coils) times (number of turns per coil) times (length of one coil.)
Total length times area (circular mils, with appropriate conversions) is volume
Volume times density is weight.

RE: to calculate the weight copper
I will add that you can always make a sample coil matching the data that you are copying and then use that single coil to determine directly the amount of copper that the complete rewind will require. In fact, the use of a 'sample coil' is a good practice since it allows you to check the fit (slot fill and end bracket clearance) of a single coil before manufacturing a complete set of coils that may not fit correctly.
RE: to calculate the weight copper
The previous proposals were correct.
But if you need an approximate value for a specific case, please, write all the data you mentioned.
I have a large collection of data for squirrel-cage motors (see excerpt attached), from which I can pull you an approximate value of the weight of copper. Of course, this value is not exact because it depends on the manufacturer, model and age of the motor ...

I understand that you have spent a lot of time and effort compiling your motor data tables. Thank you for sharing with Eng-Tips members. LPS
