The Osprey uses the latest technology of a permanent magnet generator (PMG) that replaces conventional brush and wound coil generators, which are high maintenance. The PMG uses rare earth magnet generated magnetic fields to produce electricity at lower revolutions and far higher output. The Osprey has no gearing and is mounted on a single shaft direct drive, reducing the need for ongoing maintenance.
From an ecological respective the Osprey GR-1 appears as a solid object to Birds so they simply fly around it unlike with the horizontal turbines were Birds tend to fly through the propeller and get hurt or killed.
The robust but lightweight construction of the Osprey GR-1has been designed for maximum strength and virtually eliminates the significant risk of high speed blade shear and subsequent balance destruction associated with traditional HAWT designs, an occurrence mostly associated with rare wind carried debris or Bird strikes. WTCC- Wind Turbine Charge Controller.The Wind Turbine Charge Controller (WTCC) that is used with the Osprey GR-1 was designed specific to compliment the efficient operation of the Osprey GR-1. The Controller will optimise the charge rate versus Turbine output. In simplified terms it will act like a “Clutch” on a motor car and it senses the rpm/Voltage and output of the turbine respectively, managing the load without slowing the turbine below efficiency level and thus optimising the charge into the Battery system. It regulates the AC input of the Turbine and rectifies the output into DC. The unique feature of the WTCC is that once the Batteries are fully charged there is no load dump required due to the design of the Osprey GR-1 Wind Turbine.The WTCC that ATR has selected as a preferred Voltage Regulator is manufactured by MLT Drives South Africa.
