Hi
I have removed the vacuum unit from a Eufy 11s robo vacuum cleaner. I want to repurpose the vacuum but I'm not sure how to drive the motor. I understand that brushless motors require a brushless ECS but I see that this motor has a board attached to it so I'm wondering if that is actually the control board for the motor or not. Also, the motor, as you can see in the screenshot has 4 wires coming out of it but I'm not sure which wires I'd need to connect for power, ground etc.
Alternatively, I've tried removing the motor so that I can inspect it more closely and possibly swap it out for a brushed motor but it is stuck on and I've so far been unable to remove it.
Any help with getting this motor running or at least pointing me in the right direction would be appreciate.
Alternatively, some tips on how I can remove the motor would also be helpful.
I'm not sure I understand what you mean. This is a brushless motor with four wires so I'm assuming that it is a three phase motor with perhaps a HAL sensor on it. However I don't know which wire is ground, which is the HAL sensor, if any, and finally which ones are for current.
The number of wires depends on what type of motor it is. There are millions of 3 phase motors without brushes or sensors. They are called induction motors, used in most manufacturing plants world wide,especially when getting over the 5 hp range. They have a 3 phase power source. Many of the smaller ones are powered by DC but between the DC source and the motor something converts it to three phase 'AC'.
Here is what DuckDuckGo says: "A three-phase induction motor is an electric motor that operates using three-phase power, which creates a rotating magnetic field in the stator. This magnetic field induces a current in the rotor, causing it to turn and produce mechanical energy, making these motors efficient and widely used in industrial applications."
