Re: ASRG - Performance Testing

Obtaining the 40 hr total run time through multiple start-stop cycles would
probably be even better than just a 40 hrs continuous run, because during
the time the motor is accelerating up to maximum speed the rotor and hub are
subjected to some additional side loads that are not present one the system
is at operating speed.
Adding multiple start/stop cycles would be more closely simulate the
real-life operating conditions of a rotary gap.
Yours will be a very interesting test, because if your hub is really made
from polyethylene, it will have the lowest coefficient of friction, lowest
tensile strength, worst creep characteristics, etc of any of the commonly
available plastic materials
Please let us know the progress of your testing.
