D.C Machines

Electric machines can be broadly classified into electrostatic machines and electro-magnetic machines. The electrostatic principles do not yield practical machines for commer-cial electric power generation. The present day machines are based on the electro-magnetic principles.

Synchronous Machines

A synchronous machine is a most important type of electric machine. The generating machines found in all generating stations are synchronous machines and are commonly known as synchronous generator or alternators. Synchronous motors are well known for their constant speed operation and are widely used in industries.

DC Motor Introduction, Principle and Working

A machine which transforms the DC power into mechanical power is called as a DC motor. Its operation relies on the principle that once a current carrying conductor is placed in a very magnetic field, the conductor experiences a mechanical force.

DC motor

A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. The most common types rely on the forces produced by magnetic fields.
