of electrical-mechanical equivalence. 1.3 ALTERNATED CIRCUITS (AC) As it will be shown later, alternators operate with both alternating (ac) and direct-current (dc) electric power. The dc can be considered a particular case of the general ac, with frequency equal to zero. The frequency of an alternated circuit is measured by the number of times the

## Dc Machines

Electric Machines General • When a machine is converting electrical energy into mechanical form, it is operating in the MOTORING mode • When a machine converts mechanical energy into electrical form, it is operating in the GENERATING mode • Mechanically, all machines consist of two main parts: STATOR and ROTOR. • The stator is the stationary (non-rotating) part of a machine.

Determination of machine parameters, basic protections, maintenance, and

## Dc Machine

A DC machine is an electromechanical energy alteration device. The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor.

## Lecture 6: Synchronous Machines

Construction of synchronous machines Two common approaches are used to supply a DC current to the field circuits on the rotating rotor: 1. Supply the DC power from an external DC source to the rotor by means of slip rings and brushes; 2. Supply the DC power from a special DC power source mounted directly on the shaft of the machine.
