How can I run a BLDC Motor without ESC?
Yes, you can. By making a rotating segmented slip ring with one complete six step cycle run by a small motor with the 3 line wires hooked to it. Go to youtube and search for mechanical commutation on bldc motor. You can’t even run a brushless DC motor without the ESC, let alone control it.
Does a brushless motor need an ESC?
First thing I learned was that there are brushed and brushless motors :). But, it worked, which was great, but in my research this morning I’ve come across all sorts references that you absolutely must use an ESC to control a brushless motor.
Can you make your own ESC?
For under $20, you can follow GreatScottLab’s great Instructable to build your own robust ESC. This project just requires an Arduino Nano, an L6234 motor driver, and a handful of common electronic components (resistors, capacitors, etc.).
Can a brushless DC be used as an ESC?
No, you can’t. A brushless DC motor is very similar to a three phase AC induction motor. You need to use a brushless DC motor controller (ESC) designed to generate the rotating field.
What happens if I connect a BLDC to a 12V battery?
So if you have a ’12V’ BLDC motor and connect it directly to a 12V battery (no ESC) not only won’t it spin (as mentioned above), but I’d expect to permanently damage the windings. Since a stationary DC motor generates no back-EMF, the full battery voltage will be continuously passed over one resistive winding, generating lots of problematic heat.
Can a brushless DC motor be connected to a 12V battery?
Also, most brushless DC motor controllers (ESC) are ‘choppers’ that limit the current sent to the motor, preventing thermal failure. So if you have a ’12V’ BLDC motor and connect it directly to a 12V battery (no ESC) not only won’t it spin (as mentioned above), but I’d expect to permanently damage the windings.
