"Gareth Magennis"

Some Studiomaster Powered Mixers used to adopt this method - the fan would
sit there shaking like a ****eting dog, often making various squeeks,
before finally getting going.
It was driven by a TIP32.


** A great many power amplifiers have the same kind of circuit.

BLDC fans start reliably when the applied DC voltage is about 33% of
ated - no matter how slowly the voltage rises.

IOW there is no need for a kick start.
