Motor controller wire identification. #77

Closed lebothan closed 4 years ago

lebothan commented 4 years ago

The motor controller shown in the link has on the input side a large red and back wire (presumably supply and ground) and three smaller wires ending in a plug which are not identified. They are brown red and yellow. It appears from the circuit diagram only two are used sig-esc and v-esc. Can anyone identify which these are, or how to discover? Thanks

@jcl5m1 it would be very helpful to remove the electrical tape and take pictures of all wire connections.

Johnny is recommending folks to look at the schematic. https://github.com/jcl5m1/ventilator#building

Which doesn't answer the question does it? If it did I wouldn't have the question.

Hi @lebothan , the 3 wires will correspond to ground, voltage and signal. You'll need to figure out which one responds to what with the part you have. Ground wire should be connected to ground. Leaving only 2 wires as shown in the schematic.

@steffes it is not recommended to attempt this project if the schematics cannot be understood due to the high risk factor. There are other great projects out there which may be a better fit for folks with various strengths. This project lists some options: https://gitlab.fabcloud.org/pub/project/coronavirus/tracking?fbclid=IwAR1ZptShgjzYM2ifDnxso8rJbFaIrQvOJjA--xrvk3q1Euf4KzQqErWcqLU
