One of my main concerns about IRF7862 is that I target 15A while 17A is their range at 25 Degrees. Pulse drain is 170A and using PWM we need to take a bit care because 15A on 50% PWM duty is actually 30A in PWM peak currents. If you manage 15A with 10% PWM duty…
Just a list of my designs targeting motors with new names so I can keep them apart. Name Voltage Ampere Driver Type MC2P12V1A 12V 1A DC Motor controller. MC3P28V2A 28V 2-2.5A 3-Phase micro controller. MC3X60V3ACAN 60V 2.5-3.5A New 3-Phase, 2-Phase or 3x Solenoid driver. Previously called MC3X3ACAN. MC4X24V15A 24V 15A (21A) Stepper, 3-Phase, 2x 2-Phase…
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…
