DSC01398 showing the Version 2 welded bracket. The steel bracket was fabricated from a piece of 12 gauge HR metal plate that was cut to 14" x 1.25". The length of each leg is 4.75" and the horizontal surface is 7.75" (the SME controller base is 6.25" x 8.25"). This bracket is version 2.

DSC01402 Closeup of the welded bracket on the top section of the cradle. Note that the maximum horizontal surface is about 7.75". The 3" OEM supplied bolts can no longer be inserted from the top and must now be inserted from the bottom along with an additional nut at the top. Alternatively, if the cradle is slightly bent outward, then the bolts can be preinstalled on the bench, and the cradle can then be gently bent back to its original configuration. (1/26/23) The nuts are 1/2"-13 and the bolts are 3.5" long.
DSC01399 showing the attached Controller mount on the body of a NetGain Hyper9 AC motor. The way that the cradle is factory designed, the line of draw for the bolts is inward toward the midline. A better design would be to have the bolts of the cradle vertical. This would allow for a maximum mounting surface and easier assembly.
DSC01493 with both welded cradles (version 2) attached. The useful distance between the mounted brackets is about 19.5 cm.
DSC01406 End view of the welded cradles and the water cooled SME controller both directly mounted to the cradle. The controller and chiller plate weight about 9.4 pounds. Vibration damping mounts of 0.625" diameter (1/4" - 20) with stud and inserts were purchased (McMaster 93945K11, $5.82 each) that are rated at 15 pounds each. The downward directed stud thread length is 1/2". The upper female threaded portion is 1/4"-20 and 0.25" deep. Zinc plated steel threaded rods (McMaster 95475A551, 2.25" length at $19.60 for 50). 7/8" long coupling nuts were used to secure the controller to the studs to allow easy socket wrench access. No mounting plate in this assembly.
The next generation mounting plate should be min. 0.25" taller to allow for air cooled fins to have adequate clearance above motor housing. The upper surface of the steel mounting surface should be min 22 mm from highest point (center of motor).

In both configurations below, a wiring harness will be needed that has tight bends. Possibly a braided strap or a flex braid or a copper buss bar or buss bar ground braid or a pair of custom mechanical lugs that are joined with a flexible 2/0 jumper.
DSC01497 with the SME controller located for power cables on the side. This 6061 plate is 0.125"x7.75"x10.375". Three plates were cut from a scrap piece 20" x 20" x 0.125" plate that was purchased for $29.01.

DSC01501 with the SME controller located for power cables at the end. This larger 6061 mounting plate (0.125" x 9" x 10.5") is wide enough that the SME controller can be rotated so that the terminals align with the motor terminals. The connections in this orientation are misaligned. The U1 controller terminal goes to W on the motor, the V1 of controller goes to V on the motor, and the W1 of the controller goes to U on the motor. This alignment results in the motor direction being reversed. A software alteration will be possible to wire in this fashion.

DSC01504 side view of the SME controller oriented for power cables at the end. In this picture, larger 1" vibration damping mounts of 1" diameter were used. (McMaster-Carr 93945K117 at $8.94 each). They are rated at 40 pounds each.
