I don't know much about permanent magnet alternators, but am surprised at the very un- "sine" like shape of the output waveform, on a single phase motorbike type I'm working on. It's very "peaky", with first gently sloping excursions but that then become steep spikes, like nothing in the text books. Is this normal, or am I doing something silly with the CRO? By comparison, a 240V-18V transformer I tried has the classic sinewave shape.
