Default It is a shame the photos are a little blurred.

Here are photos of the inside of the HYPERION and the Hacker motors, after the front circlip is removed, and the rotating can is removed from the stator. -As you can see, inside, these two motors are identical.</p>

a. They both have an identical 3020 (or &ldquo;3019&rdquo; stator &hellip; ). Both stators have 12 &ldquo;arms&rdquo; or &ldquo;slots&rdquo;. And both of the stators have the "white strands" on the outer surface of the stator, that has been mentined previously</p>

b. The stator is wound identically for both, and with the same copper wire.</p>

c. They have identical bearings.</p>

d. They have a very similar shaft -just that the Hyperion shaft is longer because of the longer nose of this motor.</p>

e. They have an identical diameter rotating can, both made with exactly the same thickness aluminium</p>

f. They both have 14 magnet &ldquo;poles&rdquo;, and the 20mm long magnets are identical in both motors.</p>

g. And both of the motors have CURVED MAGNETS -i.e. magnets which are curved on their interior surface.</p>

h. However, there were no blue deposits inside the Hyperion can, and there was no evidence that
the can balancing procedure has been performed.</p>


CONCLUSION: Once these two motors are taken apart, and we can see the inside of the motor -it becomes extremely obvious that the HYPERION Z3019-12T and the Hacker A30-12 L are actually the same basic motor.
And of course, this is precisely why the two motors produced the same readings on the Test Stand ...</p>


NOTE: We would never guess from the outside appearance of these two motors, that they are actually identical inside -or that they have exactly the same performance

However, even with the slight blur the Hacker windings look a mess. Just an observation.
