   DC MOTER basic information  DC MOTOR :A  DC motor  is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy.  Dcmoter image  PRINCIPLE: A current carrying conductor placed perpendicular to magnetic field experiences a force.                                                                         "Or" It is based on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a mechanical force whose direction is given by Fleming's Left-hand rule.                     CONSTRUCTION:1.1 Yoke a) Functions : It serves the purpose of outermost cover of the d.c. machine. So that the insulating materials get protected from harmful atmospheric elements like moisture, dust and various gases like SO2, acidic fumes etc.It provides mechanical support to the poles.It forms a part of the magnetic circuit. It provides a
