The Shrike 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 Shrike has no gearing and is mounted on a single shaft direct drive, reducing the need for ongoing maintenance.
The robust but lightweight construction of the Shrike1has 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.
WTTC- Wind Turbine Charge Controller
The Wind Turbine Charge Controller (WTCC) that is used with the Shrike 1 was designed specific to compliment the efficient operation of the Shrike1. 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 DC input of the Turbine. 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 Shrike1 Wind Turbine.
The WTCC that ATR has selected as a preferred Voltage Regulator is manufactured by MLT South Africa.
