Windturbine Rotor speed guard


It is a single PICAXE 18M2 micro controller based application that measures the rotorspeed of a small wind turbine.

Above the constructive maximum allowed speed, the DC generator is used to slow down the rotor speed. The breaking action is based on the technique that shorts the rotor of the DC generator.

An AXE133 LCD is used to display RPM, wind velocity and status .
