Here we have an open DC motor with permanent magnet for the field.
An old armature from a faulty hedge trimmer was used
As it was for a school project The following topics had to be covered.
Chemical energy -- We used a lead acid battery
Kinetic energie -- We got the armature rotating
Noise -- We got audio from the speaker
Heating -- We got some heating in the armature, and commutator bars
Light -- We made a special LED driven via coil
Magnetic -- We established that the armature won't rotate without the magnet underneath.
Note ! We put a 56 ohm resistor in series with the speaker to protect the speaker from a 12 Volts burn out.
