Voltage Regulator:
With this self excited control system the main stator supplies power via the Automatic Voltage Regulator
(AVR) to the exciter stator.
The exciter rotor output is fed to the main rotor through a three phase full wave bridge rectifier.

This sophisticated AVR is incorporated into the Stamford Permanent Magnet Generator (PMG) control system. The PMG provides power via the AVR to the main exciter, giving a source of constant excitation power independent of generator output.
We recommend three-phase sensing for applications with greatly unbalanced or highly non-linear loads.

Shaft & Keys:
All generator rotors are dynamically balanced to better than BS6861:Part 1 Grade 2.5 for minimum vibration in operation. Two bearing generators are balanced with a half key.

Insulation / Impregnation:

The insulation system is class 'H'.

All wound components are impregnated with materials and processes designed specifically to provide the high build required for static windings and the high mechanical strength required for rotating components.
