The Avtron AV56 encoder has a tremendous record of reliability in wind applications from blade pitch to generator control. NidecAvtron is committed to always improving our products. So we’ve created an improved model which offers easier installation, greater durability and onboard diagnostics. Ever hoist an entire blade pitch motor assembly to the ground and afterwards discover the encoder is not the problem? Now you can tell at a glance if your encoder “fault” really requires an encoder change if the light is green, the encoder is working great. Eliminate over 90% of all encoder troubleshooting and swap time! Add the remote alarm contact and know before you climb the tower! The AV56 models are mechanically and electrically interchangeable, but note that you cannot mix and match rotors and stators from the two models.
