Bowman Permanent Magnet Motor

1954 variation of the Peregrius (Perrigrinus) motor (1269).  Purportedly ran for 1 year, after which the Alcomax magnets were tested and shown to have not diminished in strength.  Replication has shown to be more difficult than thought.

  • Bowman MotorBowman Motor Open Sourcing Project - Plans posted based on a design that worked for ~3 months before it ran down due to demagnetization of the magnets.  Some speculate that a different orientation that doesn't stress the magnets as much might work better.  No one has yet been able to replicate a working device from the plans.
  • Bowman Motor (Calloway Design) Progress - latest pics compilation by Eric Vogels.  Still no independent replications, but several are close. (See Bowman index)

Eric Vogel's Bowman Magnetic Motor Instruction Site - photos, specs, parts list with sources, pics, instructions, animations, how it works, etc.  Featuring Robert Calloway's iteration of the Lee Bowman design.
This reflects well how we envision Pure Energy Systems open sourcing projects to be displayed.  Now, let's see a bunch of working devices come of this.  -- Sterling D. Allan

  • The Bowman Permanent Magnet Motor (Copy of another web page that no longer exists) - Description of motor and of inventor.
  • Peregrinus Magnetic Motor - Keelynet review, with images and diagram.
  • Bowman Permanent Magnet Motor Derived from Peregrius Motor - John Bedinini posts transcribed version of what is thought to be the first presentation of a permanent magnet motor in 1269, and describes Bowman resurrection of the device in 1954.
  • Brief mention on Bessler wheel forum - "Some free energy people who claim to have built working permanent magnet motors often claim that after a period of long duration operation the magnetic flux densities of the magnets are tested and there is no enhanced decrease as you would expect if the above were true, one famous example of this is in the case of Lee Bowman a Californian inventor who built a strange looking device that had three wheels with magnets positioned around them, (the wheels were geared to each other to synchronize their movements). This device was apparently run for a year under load! after that Mr. Bowman took all his Alcomax magnets that he had used and sent them to the manufacturers, apparently there was no decrease in the field strength."

ADVISORY: With any technology, you take a high risk to invest significant time or money unless (1) independent testing has thoroughly corroborated the technology, (2) the group involved has intellectual rights to the technology, and (3) the group has the ability to make a success of the endeavor.
All truth passes through three stages:
   First, it is ridiculed;
   Second, it is violently opposed; and
   Third, it is accepted as self-evident.

of the crowd you're a genius.
When you're two steps ahead,
