The assembled Magnevation motor driver board.
Special thanks go to John R. McDaniel for sharing this idea and a photograph of the results!
The motor driver kit has two heatsinks and two fuses held in clips. When assembled, the bottom two fins on each side of both heatsinks may touch the fuse clips or be very close. This is a tight fit and could cause problems for some builders. This web page describes a modification to remedy this problem.
The modification requires some bending of the heatsink fins before installation. Bend the outer half of the bottom two fins outward from the PCB centerline. The bottom two fins will then effectively curve around C1/C2 (viewed from above) and clear the fuse clips. The photo below shows a detail of an installed heatsink with bent fins. It also shows the amount of bending required.
