Help! How to control multiple motors with a single motor driver [Copy link]

The same is true for the robotic arm, but I can't find any relevant information. Please help me.

You can take a look at the driver board of this OP, which makes an integrated offline robotic arm controller - Motor Drive Control (Motor Control) - Electronic Engineering World Forum (eeworld.com.cn)

I found a two-in-one motor driver that can also control 3 or 4 motors. Dongguan Xunkong Automation Technology Co., Ltd.

There is a typical chip TMS28379D whose internal resources are sufficient to drive four motors with one motor. The newer 28388 chip can also do this. Its essence is to make current loop, speed loop and position loop for multiple motors at the same time inside the chip, and provide multiple output ports. At present, the computing power of the chip is constantly improving, which is enough to support the workload of four motors FOC. I don't know if this is the problem of the original poster.
