I have so many motor controller designs that I need to give them names, so I use MC + <driver type> + <Max Voltage> + <Max Current>. MC2P60V100A means 3-Phase, 60V (8-60V in this case) and 100A currents. The drawing below is an early draft. I decided to use DRV8301 or DRV8302. These are…
The Half H-Bridge channels are working very well. I initially had some issues with IR2101 as I do not have pull-up’s. but moving to IR2103 this one have logic to prevent short-cut. This is however a weakness, so I need to add a pull-down resistor so I know the state of the MOSFET before the…
Looking for a proper source for IRF7862 I realized that none of the sources on AliExpress have sold anything before. And checking Arrow I managed to get them cheaper from there at 0.59 USD each. I also notice that Pololu makes a H-Bridge based on these they claim deliver 15A without heat-sink. I tested 7A…
I got a new batch with IRF7862 and added them to the controller. Had 2 channels with working dodgy ones and 2 channels With New MOSFET’s. Increased the Lab PSU to 24V @ 10A as I tested one of the old “good” channels, moved to one of the new ones assuming it would be safe…
This one cost 32.- USD and is JK42BLS02 rated at 4000RPM, 24V and 10.6A in peaks. It also have Hall sensors and are perfect for testing my controller MC4X15A. This has similar dimensions to a Nema17, but mounting holes are located different. This was purchased for testing with MC4X15A as I needed a BLDC w/Hall…
A JY01 based BLDC Controller cost < 10.- USD and can deliver 500W. They support 12-36V and 15A driving the motor using either Hall Sensors or BEMF. I bought one of these for testing and are quite impressed over what they have done. The Driver area for 3 phases is twice as large as my…
These small, advanced controllers are a bit more work to route than you expect, but I managed to add two extra connectors as well. J1 – 4 pin 2.54 pitch connector with Power and CAN. 4x 2mm mounting holes. 60V to 3.3V DC/DC regulator TMS54060. Power Led. J6-Analogue or SPI connector. Status Led. DRV8313 with…
This is a 3D model of my new BLDC Controller “MC3X3ACAN”. 3X means 3 separate Half H-Bridge channels, 3A means 3 Ampere- it is actually 2.5A max with 3.5A in peaks. This design does not include current sensors, but I have Hall Sensors since this is my target and better for low speed applications. I…
This just show the routing of the TPS54060 based DC/DC. The upper picture show the actual routing, while the lower show the real PCB once I add the ground plane. I still lack a few details to connect ground to the ground-plane in cases where ground is on a blue (top) lane. In this case…
This module took me by surprise. I thought I had ordered a 5V to 5V isolation module, but realized it is a 240V AC to 5V/1A full PSU unit in a box that is 38mm x 22mm and 18mm height costing 3.6 USD or similar. I actually have a project that need something like this,…
