What's New At Foster

Foster's Custom Transformer Capabilities:

DC Brake / Clutch Coil

This is an example of a DC Brake / Clutch Coil that was wound as a replacement for a coil that was no longer available from the manufacturer.  The photo above shows the finished coil and the coil being wound as an inset.  

The wire inside the coil is 2 strands of 2 AWG solid copper wire.  Each strand is over 1/4" in diameter. With our in-house tooling capabilities we were able to create the tooling necessary to wind the coil quickly and at minimal expense.  The finished coil has an 8 inch center opening, 12 inch overall diameter and weighs 69 pounds. The coil is wrapped with glass tape and vacuum pressure impregnated with an epoxy resin to provide enhanced electrical insulation and to protect the coil from physical damage.
