I´m looking for a less noisy alternative to using servos for a project and I was thinking of using musclewires (Flexinol / nitinol wire) as an replacement. I havnt worked with musclewires before and wonder if this is possible or if they are very slow (I know they are driven by heat so slow...
Thanks for the answers. I did some research and did this calculation:
circumference of the spool: diameter of the screw * PI :: 1 * 3,14 = 3,14
Length of wire: Number of turns * circumference :: 500 * 3,14 = 1570 cm
The resistance of the wire / cm (ohm): 0,00032
Total resistance of the wire...
Im making an electromagnet that will be more or less permanently turned on so I need to avoid heating problems. I have studied this a bit and came to the conclusion that:
the lower the gauge (AWG) (the thicker the wire) and the more turns around the core => the greater current it can handle and...
