Motor Controller Pictures

We received our motor controllers sometime around August 2020. Once we got access to the bay, I opened the box and took it apart to inspect before doing anything else.

There were some pretty interesting things I found.

 

Above: Standard box, comes with a CAN cable, and a motor controller interface board (pink bags) - I didn’t look in to those too closely, but it basically gives access to the CAN bus and maybe a few other things. Also includes a CAN-Ethernet adapter.

Above: The 8 threaded holes are for the heatsink mounting, the rest of the dots visible are studs that hold the board in place. The studs in the middle are for the FETs.

The top cover is pretty thin, so will not do much in the way of cooling.

The bottom and sides are much thicker (maybe around 4mm) and give some great heat spreading for the MOSFETs. All the studs have a Nylon Locknut on them, but interestingly for the ones on the board the threads do not seem to get to the nylon part of the insert. Might not be a bad idea to check the torque and maybe add a secondary locking mechanism for these (Electrical / kapton tape around it, or add threadlock or something).
