All movies are in RealAudio format.

• Poor Man's Pulse Motor (PMPM) videos - A little bit of fun and a good way to learn how magnetic fields interact.
• 1. Clip 1 shows the rotor and bearing assembly.
  2. Clip 2 shows the position of the magnets on the rotor.
  3. Clip 3 shows the 'drive' magnet of the motor.
  4. Clip 4 shows the motor in motion and speculate on practical uses.

• Mk 1.0 videos - My first attempt at making a pulse motor.
• 1. First attempt. Notice only 4 small magnets in the disk.
  2. A better running model thanks to bigger magnets and an increase from 4 to 8 on the rim.
  3. Here is a nice smooth and quiet test that uses a coil pickup to trigger the transistor.
  4. An interesting effect I found I call Motor Music. It is really called magnetorestriction.

• Mk 4.0 videos - It is a little inconvenient to take video as my camera is attached to my computer and my shop is in the basement. So I do this with much caution while in my living room! ;-)
• 1. This clip shows the Fulcrum or: Moment of Maximum Magnetic Im-balance.

• Mk 5.1 videos - Well here is a video and explaniation of my latest motor that displayes no current draw when mechanically loaded.
• 1. Here is a link to the lowband (1 meg) video I made: Lowband
  2. Here is a link to the mediumband (2.5 megs) of the same video for those of you with better internet connections. Mediumband
  3. Larger 7 meg Widows media file. If file does not download, right click and choose "save to disk".

• Mk 5.11 videos - Video demo and explaniation of my latest motor that displayes no current draw when mechanically loaded as in Mk5.1. Yet this model has four 'secondary' coils that help charge and run from the tank cap to over 100 volts. The secondaries can be seen to dislpay the same no drain of electrical power to the system yet the recapture cap that they are wired to, stays 'charged' under load!
• 1. Here is a link to the Mediumband(2.8 megs) video. Lower bandwiths degaded the quality too much so this is the smallest size.
  2. Larger 7.6 meg Widows media file. If file does not download, right click and choose "save to disk".

Note: More to come.... stay tuned.

CAUTION: The information here is for educational purposes only. Any attempt at replication is done at full liability of the one replicating it. These motors can develop high rpm and high voltage depending on how they are designed. Build and operate at you own risk!
