How to Wire a Slip Ring to a Wind Turbine PMG


In the video above, Jeff demonstrates how to hook up a slip ring to our Freedom and Freedom II PMG, though you can use the same method for nearly any wind turbine PMA or PMG on the market.

Below, we’ll break it down below to make it easy to follow:

Connecting the Slip Ring to the Mounting Bracket

One end of the slip ring will be fixed and the opposite end will rotate.  The rotating base is the bottom end of the slip ring and will connect to the wind turbine rectifier(s).  Be sure that it faces downward to prevent rain from entering the housing.

Slip Ring to Wind Turbine Direction

Feed the wires from the slip ring through the top piece of the mounting bracket and secure with self tapping screws.

How to wire the slip ring to our 2000 Watt Freedom II PMG:

Separate three of the six leads from the top of the slip ring (we use this one) and secure with electrical tape.  Repeat this process with the same three colored leads extending from the bottom.  This important step will keep you from shorting out the PMA or PMG.  

Slip Ring Leads

  • Each set of leads from the top of the slip ring will connect with separate leads from each wire harness that extend from the Freedom II PMG.

  • Three leads from the bottom will connect with one three phase rectifier (you will use two three phase rectifiers, included when you order a Freedom II PMG).

Use SJOOW cable with your Freedom II PMG

Wiring method for 1600 Watt Freedom PMGs:

Separate the top three leads from the slip ring, these will connect directly to the wire harness from the Freedom PMG.  Connect any color lead to the wires extending from the PMG.

Slip rings are not required with our wind turbine generators but some people prefer to use them.  In that case, we want to help our customers understand how they should be connected to the wind turbine components to prevent damage from the unit.  If you have any questions, please don’t hesitate to contact us.
