The Hammond A-100 Organ, History, How it Works, Maintenance, Operation and Features.

This video gives the story of why the Hammond Organ was created, how it works internally (generates notes with tone wheels), how to add oil annually, and how to use the drawbars, keyboards and other features of the organ, demonstrated by Tyler of Boss Organ, in Somerville, Massachusetts. Although I use the word "electromagnet" in the description of how it works, what you see is actually a permanent magnet (the rod) with a coil of wire mounted at one end. When a tooth of a tone wheel comes close to the tip of the magnet, the magnetic field is strengthened slightly, which induces a tiny current in the coil. When the tooth passes by and the tip of the magnet then faces a gap between the teeth on the tone wheel, the magnetic field is reduced, which induces a current in the coil in the opposite direction.
