U.05 Electromagnetism

Day 09 - CAD Design Work

Yesterday you had a chance to play around a bit with TinkerCad's 3D modeling software. Today we're going to attempt to model out 3D collars that will fit around the spindle of our electric motors. We're going to borrow calipers from Mr. Bridges and take 3 measurements of the spindle:

Although the spidle is a cylinder, it has been flattened on one side. This means that there's a diameter to the round part of the spindle and a diameter to the flat side of the spindle. Measure them carefully and record your measurements to the finest degree possible. A tenth of a milimeter of error will be enough to cause problems with this project.

coil
a layered loop of conductive material (such as copper); current through this loop will produce a magnetic field
commutator
a cylinder with a break in it such that as it spins it keeps breaking the circuit for a moment to allow a reversal of current
current
in electronics, it is the movement of electrons through a circuit; this movement can be direct (flow) or alternating (vibration)
dynamo
a generator that converts movement (mechanical energy) into electricity (electrical energy)
electromagnetism
the physics invovled with the flow of electrons and their magnetic fields
generator
in engineering, a generator is any device that outputs energy in a specific form (often electricity)
magnetic field
the accumulation of force from millions of electrons aligned in the same direction, making the substance behave like an ionic element
