Overview

PERMANENT MAGNET GENERATOR
PMG-LT for Lighting Towers

The system consists of a three-phase permanent magnet generator, complete with its proper lamp starters, supplying the lamps of a ligthing tower.
Lamps are gas-discharge lamps, and they belong to HID (High Intensity Discharge) family; they are metal halide lamps series HPI, conteining high pressure mercury and a mixture of metal halides.

The generator has been realized with a three phase permanent magnet (Nd-Fe-B) machine in order to obtain a high power density and reduced volumes.
The stator's winding is inside, while the rotor runs outside.

Technical Features

Differently from a standard alternator, the output voltage is supplied at a higher frequency, making possible a series of advantages, both mechanical and electrical:

At the same output power, the PMG-LT alternator is more compact, with smaller overall dimensions, even concerning the lamp starters.

Efficiency is close to 90% (usually, with a standard alternator, it is about 78-80%).

The needed input power is lower, so it can be coupled with a smaller size prime motor, reducing prime motor’s fuel consumption.

Possibility to couple it to an inverter (only for PMG-LTI), in order to have also available a single-phase output voltage, with a ±1% voltage accuracy, regardless of cosφ.
