Each of the wheels on this thing is pretty equivalent to a VCO that
can make at least a sawtooth wave (and you can easily generate a
square/PWM wave from that). Each motor's speed goes up and down to
make the wheel make different pitches. It's basically a VCO for an
analog synth.

Hammond uses a bunch of tonewheels that are all fixed speed and each
outputs a sine wave only. Different sounds are made by mixing together
up to 10 or so harmonically-related sine waves for a note. The
relative levels of these waves make for the timbre. It's kinda-sorta
similar, but has a lot of differences. The motor thing is for
subtractive synthesis (generate a bright waveform and then filter out
some stuff) whereas a Hammond is additive synthesis (add up a bunch of
sine waves to make the tone you want).
