Wind chargers from Ampair. We manufacture wind turbine systems ideal for use in remote locations, on board yachts and in scientific laboratories.
The Ampair 100 wind chargers are unrivalled when it comes to choosing wind turbines with total reliability when it comes to charging battery systems. They only output one hundred watts but can still out perform turbines that output four hundred watts of power, they can perform even when the wind isspeed is low.
It has been designed to survive in the most severe of marine environments. These wind chargers are heavy duty perfect in all weather and double sealed to help prevent corrosion. This range of turbines is often found in radio repeaters. They help to save on the cost of fuel and there is no need to run noisy generators.
The ampair wind chargers are available in white and silver. They are all designed in the same way there is no difference in them at all.
The unit of these wind chargers consists of a two part cast aluminium body, the two parts sealed by an "O" ring. Two six pole permanent magnet rotors run, with their poles in line, on a stainless steel shaft. The shaft runs in two sealed. grease-packed ball bearings with the front bearing protected by a shaft seal. Two six-pole stators are arranged with their poles staggered at 30 degrees to minimise cogging or break-out torque and so allow easy starting. The unit is assembled with one stator in the main body casting and the other in the nose piece. During assembly these are precisely aligned on the test bench to give optimum performance. A small timing mark is made at the junction of the case halves to allow accurate re-assembly.
The alternating current output of the stators is rectified by two bridge rectifiers, one per stator. The DC output of the two rectifiers is paralleled and passes to two carbon brushes mounted in brush holders located on the sides of the lower body section. The carbon brushes carry the output to two phosphorbronze slip rings mounted on the stationary pivot shaft, allowing the machine to rotate to follow the wind. To absorb any electrical noise arising from the slip-rings and brushes, a metal oxide varistor is wired across the output between rectifiers and brushes. The output is electrically isolated from the case.
