Make a Heatsink for Stepper-Servo Motor Drives

While organizing the electronics for a CNC conversion, plates are made to hold functional units that can be moved along DIN rails. One of these is a plate to hold all the drives for the stepper-servo motors (Leadshine ES-D508 Easy Servo drives). A plate that also serves as a heatsink is designed, machined, and tested. Lessons learned are discussed and testing is done using thermography.
