Product Description    

The generator is driven by its engine in the correct direction at its rated speed (RPM). DC Field current is then supplied to its field winding through the brush and slip ring arrangements. The poles produce sufficiently strong magnetic flux. Since the poles are rotating, the magnetic field is also rotating. The armature windings in the stator windings cut the flux of the rotating poles. Therefore electric power is produced in the stator winding. 

An AC generator converts mechanical form of energy into electrical form. It is a device which converts electrical energy into Mechanical energy. Both these devices consist of a coil that rotates inside the magnetic field of a magnet. AC generator is used as an alternative to electricity. It serves many purposes, which are also used in other devices like pulleys etc.

Banking on the skills of our qualified team of professionals, we are involved in offering supreme quality array of DC-AC ring generator.

Typical ring generator application:

Ring generators are used with telephone switches to provide ring signal. Following are some application circuits:


(1) Unbiased circuit

Fig.1 shows unbiased application circuits: (with 48V input voltage)

(2) Biased circuit

Fig.1 shows biased application circuits. This circuit (when input voltage is 48V and output is 75VAC) generates ring signal of -48V+75VAC. The bias can be changed as needed.
