Hi all,
I've been given a project to look into for my company and basically I need to come up with a design to automatically raise and lower a magnet using a small motor.
The idea at the minute is to attach the magnet to a piece of string/wire and use a motor to wind up the string to raise the magnet. After the magnet has been raised to a set height, the motor then needs to reverse to lower the magnet. Ideally, this needs to happen continously for an 8 hour period without any user interaction other than initially turning the system on. The magnet is small so there are no significant loads involved. The magnet does not need to be raised particularly quickly but does need to have a vertical displacement around 600mm.
I thought a stepper motor was ideal for this purpose as it can be set to turn a set number of revolutions and then perform the same number of revolutions in reverse. However, I am a Mechanical Engineer and must confess I know absolutely nothing about electronics! So bearing that in mind I would like to know exactly what is required to create the set up I mentioned above.
I apologise for the extremely sketchy information but this is still in the very early design stages, and I will try and answer any questions as I go along. I would be extremely grateful for any help. Thanks very much.
