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,…
This is my first attempt on a 60V to 3.3V DC/DC converter. I am using the reference diagram for TPS54060 with a few modifications. Starting at left I use a SS16 Shotky diode + a 1000uF since this is for a motor driver. You can otherwise use far less capacitance on the input. I left…
The drawing below illustrate my New, planned DRV8313 based BLDC Controller Design: This will give a small BLDC Controller capable of 8V to 60V operation with up to 2.5A on 3-Phase motors with or without Hall sensors. 8-60V operation Perfect for 12V, 24V or 48V systems. Up to 2.5A motors Sensorless or Hall Sensor driven…
I found 2 series of DC/DC converters that can handle 60-75V from TI that also is available from AliExpress showing that they have some popularity. These all cost around 1.2 USD from my sources and are decently small. These converters consist of a chip with build in MOSFET’s and PWM generator so you basically add…
This show DRV8313 used as a PWM driver on a PLC Module. This way I can get from 12 to 24 PWM channels with up to 60V @ 2A each. This gives an insane combination of 8 x BLDC Motors, 6 stepper motors, 12 DC Motors and 24 Solenoids. I need to think about this…
If you search for schematics you will notice that DRV8313 is far more popular than DRV10983. DRV10983 only support 28V, while DRV8313 support 60V, but the most important difference is that DRV10983 needs to be programmed through I2C while DRV8313 have direct PWM per half H-Bridge. The 3D model above show the DRV8301 based design…
