When a current carrying cunductor enters in a magnetic field , a force is produced on it.

[tex]E = \frac{{NP\phi Z}}{{60A}}[/tex]

[tex]V = E + {I_a}{R_a}[/tex]

[tex]V = E + {I_a}{R_a} + {V_b}[/tex]

[tex]V{I_a} = E{I_a} + {I_a}^2{R_a}[/tex]

[tex]{\tau _{av}} = \frac{{PZ}}{{2\pi A}}\phi {I_a}[/tex]

Electrical Machines or Devices is a general term for machines where electromagnetic forces converts into other forms of energy i.e mechanical energy, Electrical Energy, heat, light etc or vice versa.

DC motors

Direct Current Motors (DC Motors)

Motor -- a machine converts electrical energy into mechanical energy. Construction of D.C motor is similar to D.C generator. Most types produce rotary motion. Another type is Linear motor which directly produces force and motion in a straight line.
