Step 1: Design the actuator you have always wanted. Step 2:
Enter the specifications You will have to manipulate the gap
height parameter to find the gap height that gives the best flux
density (least power) while not exceeding whatever spatial
limitations you might have. As you play with this, you will not
that the equations break if you choose this parameter unusually
low or high. Step 3: Machine the stator and bobbin A couple of
tips on this step. Machining a deep pocket in Iron (or soft
steel) for the stator is a pain. As a alternative, you may
machine a cylinder and a disc. Place the cylinder on a hot plate
and the disc in ice water. After the cylinder is at 500 oF and
the disc at 30 oF, slam them together using an arbor press
(exciting). The bobbin should be made out of aluminum or
plastic. Be careful while assembling the magnet and flux puck
into the stator cup. It is recommended to machine a guide for
the magnet and puck so as to avoid losing digits. Step 4: Wind
bobbin Wind the magnet wire onto the b
