DC motor assembly

  • Provides a basic understanding of the inner workings of a DC motor, driven via current passing through a conductor between two static magnetic poles. 
  • The student must correctly position the magnetic poles in the stator, wind the wire around the rotor in a uniform orientation, cope with the possibility of reversal in rotor velocity, and troubleshoot any malfunctions (short circuits, erroneous assembly etc.)
