I built the following circuit to test a concept of Don Smith it is not the same as your motor as it drains the battery of any current such that it will not run anything yet it retains its voltage to a major extent.
it was designed to use the base collector as a diode rectifier to collect any reverse charge pulse from the oscillators and it has run for more than 38 days before i stopped it lighting a LED the whole time.
though it is not the same it may have some clues for someone here as a reverse action to what you are seeing so want to pass it along.
