Pitched Style Roof ·Vertical Axis Wind Turbine with sails that can receive wind forces from any direction. Including up and down winds. ·Magnetically Levitated – reducing friction, noise, vibration and energy loss. ·Axial Flux Alternator – Allows it to generate large amounts of electricity at low rotational speeds. ·Roof Mounted – Does not require a tower, allows the wind turbine to take advantage of air-compression velocity increases from roof effect. ·Programmable Variable Coil Resistance – allows the increase of magnetic resistance as the wind speed increases. This reduces the cut-in wind speed required for electricity generation. Overcoming Challenges of the Conventional VAWT concept: ·The ‘conventional’ VAWT has bearings to change oMVAWT uses magnet levitation, which does not need regular maintenance. ·MVAWT starts at low wind speeds oVariable resistance coils - controls Drag. ·MVAWT accepts wind from multiple directions oSail design accepts all winds even from above. ·The ‘conventional’ VAWT suffers torque ripple effect. o MVAWT has no drive train to torque. ·The ‘conventional’ VAWT suffers wear and tear from vibration oThe MVAWT is magnetically levitated, so there is no vibration.
There are five main aspects that affect the output of our wind turbine: ·Wind Speed – Site wind characteristics. ·Roof Effect - The shape of the roof can increase or decrease the performance ·Coil Output – Number of coils ·Sail Size – surface area and configuration of the sails ·Inverter – the maximum amount of electricity is limited by the size of the inverter. 10 KW - Model MW-2200
