Those are permanent magnet DC motors. The armature (the part that spins) generates a magnetic field that interacts with the permanent magnets and causes it to spin. The relationship of the brushes to the magnets sets the 'timing'. People that have raced remote control cars know all about this. On ...

I had an instructor back in the day (too long ago) that liked to argue with himself about electron flow versus 'hole flow'. He was an interesting guy.

I'm not sure something like this could sustain itself for any longer than just the motor on the battery alone. You lose energy due to friction, the ...

I'm not sure I'm following what you are doing. I was thinking you were going to use a generator turned by some sort of mechanical means to generate voltage to run a DC motor.

The rotating field of a generator produces AC, if you rectify it you can get something near DC with it, and even closer to DC if you filter it, usually by putting a large capacitor on it. Be careful if you mess around with any sort of home made generator as collapsing magnetic fields can produce ...

If you are rectifying the output of the generator and feeding it to the motor, you should get more voltage and the motor should go faster as the generator goes faster, assuming the motor is a DC motor. You would have pretty ugly DC but it should get the job done.

I work on industrial controls for a living and I've done quite a bit of PLC and DCS programming. As a side project for a friend of a friend, I used Flowstone and a Labjack U3-HV with the relay board in an effort to automate a small readi-mix concrete factory. The basic operation is to put the ...

I wrote a Flowstone program to communicate with a cheap Koyo Click PLC using RS-232 MODBUS RTU and it works fine. Let me know if you still need some help.

Flowstone runs the schematic as soon as you open it. Sometimes this can cause a little trouble because some strange things can happen as you draw your schematics and everything isn't connected. I have a labjack u3-hv and it works great with flowstone. You do have to click on the three triggers to ...

I found some ruby code online. Seems to work. Try out the attached module.
