Department of Physics and Astronomy PHYS 420: Physics Demonstration. THE uncovering of the theories behind a motor. University of British Columbia Presenter: Eric Yeh. What are we doing today?. We are going to learn the basic functions, principles, and applications of an electric motor.
A rotating machine that converts electrical power (either alternating current or direct current) into mechanical power.
Is this definition very satisfying?
There are couple main principles behind a working DC Motor.
In simple terms, they are:
Cut the wire, leaving a 8 cm tail opposite the original starting point.
Wrap the two tails around the coil so that the coil is held together and the two tails extend perpendicular to the coil.
On one tail, use fine sandpaper to completely remove the insulation from the wire.
Leave about 0.5 cm of insulation on the end where the wire meets to coil. On the other tail, lay the coil down flat and lightly sand off the insulation from the top half of the wire only.
Again, leave 0.5 cm of full insulation on the end and where the wire meets the coil.The Motor that We are Building
Synchronous generators are most often used for "emergency" or "standby" power, but in many cases may be used to provide all of the power requirements of a facility.
Induction generators are most often used for "peak shaving" (providing the power needed for starting large motors, additional air conditioning load on hot days, etc.)
