Mostly Permanent Magnet Motor with minimal Input Power

[FatChance!!!]

I don't want to spoil your hopes but this design is nothing but a regular electric motor
being run sideways like a piston instead of circular movement.
As we all know, the force from an electric motor is determined by the the sum of the
input current x input voltage minus the losses (mostly I2R).
As your coil slides along the magnetic field an induced voltage is formed.
The faster the coil moves the higher the induced voltage. In your case the movement is
very slow and the induced voltage is small and so is the torque output.
The efficiency of an motor is determined by the difference of the induced voltage and
applied voltage and current. The loss is explained by I x I x R, namely I2R.
Your motor is running at No Load, therefor the input is small. Try loading it and you'll see
the input power increasing as the RPM drops like a rock.

But I have to admit it's a really cool design. Keep up the good work.

Okay I see,

it would work but one thing to consider in wattsup's design is maybe the quick launch (at desired time) may cause a braking of the wheel at that timing point???

Yes but perhaps the braking effect (i.e. the reaction for the quick launch action) could be kept acting mainly onto the shaft in the radial direction, I mean the launch should take place just after passing the 12 o'clock position, this way the braking effect on the rotation of the wheel will be at the minimum possible.  (the later you launch from the just vertical passing position the bigger the breaking effect is if the RPM is not high I think, maybe wrongly?).

The braking effect is inherently included in wattsup's design anyway, my suggestion for some improvement in lessening input power does not change this, unfortunately.

Hi I am working on a similar idea but the reverse of what you have illustrated.

I posted this on U tube and its not perfected yet. Right now I am making a reciprocating magnetic arrangement that uses two magnets on one shaft. I used one magnet in this video. Also will use two coils. I have reached speeds up to 1560 RPM with torque so far. Hope to better the speed to 3,000.  My design is powered by a 30 volt peak to peak square wave. I adjust the motor speed with variable low frequencys.

When I feel I have enough motor torque I will be finished working on it. That takes it into something that can be usefull rather than a curiosity which it is presently.

I love your design. We think in reciprocating directions.
