I normally use unregulated 27V off the bridge rectifier for DC power to my BLDC motors. But I have a case where I want to drive two motors under a heavy load and I know it would stress my power supply. The blue transformer is rated at 2.6 amps (1.3 + 1.3). 6 amp bridge rectifier. Never blown one up even when I have measured 6 amps load for a few minutes of operation. So I looked at McMaster and they had a 10A din mount supply. $220. I felt like this would be overkill for the purpose. I put up two motors on the table, no load. I was putting some load by grabbing the output of the gearbox with some pliers about 3-4 times to see the current via ADC output on the LCD. No where near the load the motors will really have on it in the real world. Next thing I know the motors stop. Omron LED is off. Powered off and on. Nothing. Hour later. Nothing. What the heck. The Omron is the large black module in the gray box. S8VK-G24024. I put in a back plane and mounted the omron on the plane with an aluminum bracket. I added thermal grease on both surfaces to move some heat off the box.
