Oscillating sine wave LC tank magnet motor.

Rules for the operation of synchronous motors:

"The second method of starting a synchronous motor is to attach an external starting motor (pony motor) to it and bring the synchronous machine to near about its rated speed (but not exactly equal to it, as the synchronization process may fail to indicate the point of closure of the main switch connecting the synchronous machine to the supply system) with the ponymotor. Then the output of the synchronous machine can be synchronised or paralleled with it's power supply system as a generator".

A DPDT would be needed. We run it up with the turntable motors, switch them to the neutral position, then turn the A.C on and power with synchronous A.C.  Flop the generators on to a closed dimmer switch "Then the output of the synchronous machine can be synchronized or paralleled with it's power supply system as a generator".


This is by no means an original idea. Parts adaptaion, innovation, not invention. Two dimmer rheostats might be needed so the power is phased in synchronized and paralleled. Turn down the wall current with one dimmer and at the same time feed increased generator output into the power coil with the other. The generator dimmer turns up to full on, while the wall current dimmer turns down to nearly off.

Look at the perfectly round bundle of 1/4" diameter by 1/2" long diametric tubes. The natural alignment is N.S.N.S. etc. Six or eight of these magnets glued to flat ends of bottle caps would glue just right to the turntable rotor magnet and hold together by natural attraction.

The 1/4" by 1" cylinder is one of our most popular sizes due to its great versatility. The D4X0DIA-N52 is a little different in that it is diametrically magnetized, which means the curved sides will attract instead of the flat ends. And since it's Grade N52, you know it's as strong as can be!

What effect would doubling the magnet strength, by doubling the length of the cylinder magnet and then doubling the diameter of the thick gauge A.C. power coil have on motor performance? Would there be any increased input cost to run a rotor and coil twice as large and powerful with synchronous A.C. frequency?

We can see the natural dlametric magnet  A.C. rotor shape again in the picture  above.

We get to sort through a junkbox full of old plastic bottle caps to complete the motor.

Those bottle caps triggered a flashback to an acid bummer from the "Old Filmore".

On further consideration I realize the need to connect the rotor bearings together with one solid piece of pipe just the right size, then drill holes and press axial polarized cylinders where they would glue fit and link in the center around a tiny steel ball bearing.
