GENERATORS
Battery Charging
- two x 250mm 36 pole 3 phase permanent magnet 48 volt generators connected to a custom built controller incorporating a braking/load dump.
Grid Connect
- 1 x 300mm axial flux 3 phase 48 volt generator using neodymium magnets connected to a custom built controller incorporating a braking/load dump.
TOWER
- 65x65x5mm angle iron lattice tower 8 metres tall with a 2.5 x 2.5 metre footprint. The design for this tower has been approved and certified by Bullock & Partners consulting engineers.
To understand the concept of extracting energy from the wind, it should be noted that the energy available from the wind rises in proportion to the cube of the wind speed. This means that during a light wind the turbine makes only a small amount of power, however as the wind speed increases, the power output increases considerably, so if the wind speed doubles it will produce 8 times more power.
The traditional 3 blade horizontal axis wind turbine is a lift design and as such the tips of the blades go faster than the speed of the wind and therefore whistle. The turbinator is a vertical axis wind turbine and is a drag design and spins much slower and is completely silent. This design creates a lot of torque so the generators are driven at 5 times the speed of the blades.
The standard tower is constructed from 65x65x5 mm angle iron 1500mm square at the top and 2500 square at the bottom and 8 metres tall.
This tower has been designed in conjunction with a consulting engineer and has been certified and a copy of the calculations are available to assist in obtaining council approval.
