maintain initial and end position stepper motor without energy loss Answered
In a project of automated vertically folding curtain I have the problem that whatever the position of my curtain (8 kg) is, the motor is always drawing current. Let's say the curtain stays for 8 hours in the same position, then during these 8 hours the motor is wasting lots of energy.
Is there a method/mechanical system which can be used to make sure the motor only uses energy ("works") if the position of the curtain has to change?
Thanks in advance
