Single phase, chain driven alternator project with ferrite magnets

Chris Olsen has been busy experimenting and reporting his findings on the Fieldlines board

This single phase stator for a ten magnet dual-rotor turbine is his answer to the rising cost of neodymium magnets.  As always Chris is pushing against the accepted way of doing things (3-phase, direct drive etc) so his project gives rise to some interesting discussions.

As an update to this post I offer this link to a discussion on the ‘Backshed’ forum where Chris describes his latest (2-bladed) creation and I argue the case for single stator alternators.

About hugh

I live off-grid in NW Scotland and have spent my life playing with wind turbines. I also love small hydros. Hands on renewable energy is my thing and I like to learn and to share my experiences.

    i do follow mr.chris works on his youtube and fieldlines documentation, and definitely he was./is one among the inspirers on these projects.
