Newman may be simulatable in LTSpice as a legitimate motor that does not possess overunity...

And Newman himself failed to account for all energy sources in the Newman device. They left out the value which a rotating magnetic field has on the Newman Coil produced by the spinning permanent bar magnet/s in the Newman device. This spinning field consolidates its energy as an amperage dominant input while the batteries consolidates their contribution as a voltage dominant input creating a sort of dipole which is maintained by virtue of the isolation between them across the mutual inductance between the coil and the spinning bar magnet's field - not unlike an isolation transformer. Under these conditions, it is possible to achieve a negative current at the battery pack to block any drainage there...

Newman's machine produced mechanical advantage in the form of torque dominating over speed. Hence, it did not do well as an EV motor. Also, it required too much time to alter its voltage and hence alter its speed of rotation creating another hindrance to functioning as a useful EV motor.
But working off of his original design, a few modifications can render his motor into an electric generator capable of supplying amps to an EV's motor and supply varying amps to modify the EV's speed...

BTW, the National Bureau of Standards admits in their report to shorting out the Newman coil by connecting a resistive load in parallel to the Newman coil of lower resistance than the Newman coil. Thus, a current division circuit was established in which a greater percentage of current would want to travel the Bureau's test load's path of least resistance rather than travel the path of greater resistance through the Newman coil and, thus, invalidate the test as being a non-exclusive test of the Newman device.
