SX460 AVR - STANDARD
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
