Hyper9 Motor Support and Cradle - Version 1

Purchased a Stainless Steel motor cradle from NetGain Motors (part MC-H9225 for $112.50).

The pair of galvanized steel clamping bolts are 3.5" long and 1/2"-13 coarse thread (3/4" socket head).   Stainless Steel replacement bolts for $3.13 each are available from McMaster-Carr ( https://www.mcmaster.com/93190A726/ ).

DSC01366 Closer view of 1/2" bolt assembly of the cradle.  The bottom of the cradle uses a pair of steel narrow-base weld nuts, 1/2"-13 thread size  (McMaster 90594A033, 25 units for $22.27).  It is important to align the bolts correctly to engage the lower threads and not cross thread them..  The top fitting is just a thick washer that is crimped fit to the top of the cradle (no threads).

DSC01366 Bottom view of  the base of the cradle.  The metal band is 3 mm thick and 37.75 mm wide (about 1.485").  The pair of mounting holes have a diameter of 0.59" (15.0 mm) and either a  9/16" or 14 mm bolt will pass freely.  The mounting holes are 215 mm (about 8 7/16") center to center.

Air Cooled Hyper-9 Chill Plate

If one is not interested in installing a glycol/water based cooling system along with the Hyper9 controller, then an air based cooling system may be an alternative.  If properly constructed and mounted directly over the Hyper9 motor, then accompanied with a forced air fan, it may also be possible to gain some cooling for the motor at the same time.

In review, the dimensions of the Hyper9 controller are 8.25" by 6.25", and the overall length of the Hyper9HV is about 14" with a maximum width of  9".

Several sample chill plates were purchased and modified and they are shown in picture DSC01355.  All of these chill plates are extruded 6063 alloy and they are manufactured in the USA.  The sizes shown are 14" x 8.5" (top left), 14' x 7.25" (top right), 7.25" x 9" (bottom left and center left), and about 8.5" x 7" (bottom right and center right).  All of the chill plates have a fin height of 1.0" and an overall thickness of about 1.30".

DSC01358  with a paper template of the controller on top of the fins of the chill plate.  These fins run perpendicular to the long length of the controller.  The picture shows the template on the same side as the fins, but actually the controller would be on the flat opposite side.  We plan to also use a heat transfer paste between the flat surface of the controller and the flat surface of the Chill Plate (to be reported later).

DSC01362 top view of the 14' x 7.25" chill  plate with paper template of the controller in place to demonstrate the range of location that is possible.  This plate is equivalent to the 7.25" x 9" plate shown in DSC01359, but it is longer and it allows for greater variation in the placement of the controller.   


                                          

DSC01357 of  a chill plate that is 14" x 8.5".  This size can allow for a pair of controllers to be mounted on the same surface.  The fins run perpendicular to the long dimension of the controller.
