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).
