The GOVERNATOR - How vintage DC tape recorder motors work!

The Governator isn't just in California! This video explores the mechanics of vintage battery powered DC motors that were common in the 1960's and '70's. There is a lot more going on inside the motor case than meets the eye! DC motors used in battery powered tape recorders (most commonly capstan drive reel to reel and cassette tape recorders) had to meet a very specific requirement -- that of providing a constant tape speed across the record/play head under a variety of voltage conditions. A simple DC motor (which is voltage controlled) simply was not up to the task. So the vintage tape recorder manufacturers came up with an amazing solution that uses Newton's Law! The device is called an "electro mechanical governor", and almost all vintage tape recorders that offered capstan drive had motors with a governor built in. See how they managed this complex problem by applying a little science to the task at hand and came up with an engineering solution that lasted for almost 40 years! ******** Sponsored by: Get It Done!
