Inertia Drive project. RFDD.

[tinman]

Well here is the start of my Inertia drive project-the RFDD engine.

The plan is to use elliptical orbits of mass(in this project,i call them satellites)to off set the reaction force associated with all actions-Reaction Force Diversion Drive (RFDD).

If successful,this will be the only video posted,until the test video's are presented. If un successful,you will see all the build progress video's along the way. The project is expected to take 3 to 4 day's,so the next video will be posted around that time.

The plan if successfull.
After i have run various test on the device,and found that it works as planed,it will be time to choose one other person to replicate the device,run and report on there test finding's. The chosen person will be given the full build video's and instructions. This person must have access to a metal lathe,and a healthy budget for the project(around $200.00 for parts).

The plan if unsuccessful.
Dont do it this way again.

Just a video on the PWM build and tune for the RFDD.

That's aa nice looking little board.  What IC does it use?

It uses the TL494 IC.
This is a sweet little unit,and having the variable frequency is very useful indeed.I have tried it with a couple of different motors now,and im quite supprised as to how much you can reduce the power draw just by changing the frequency of the pulses,while maintaining the same output torque on the motor.There is another thing i forgot to mention on the video,and that is you can remove the soft start just by removing a jumper plug. The frequency can also be made to go higher,simply by replacing one of the caps to a smaller value,or one of the resistors to a lower value. Maybe later on i will just replace that resistor with a V/R.Bellow is the circuit.

That looks like a decent design for a low side switch driver.
