Three-phase motor
Thanks for the prompt response. I consult you because one phase was missing and the engine was running without force. When I wired from the thermal to the motor again, I had less movement than before. I try to swap phases between two of the three phases and when I give tension it makes a flash. With my little experience I thought I burned it.
The engine house technician told me that it is possible that the winding was burned by working with two phases, and that none of this would have happened if I had an own circuit breaker for the motor. Is this real?
It is like that. If the engine was running and a phase was removed, it will continue to spin but will burn. If it is stopped and you connect two phases instead of three, it will not start and if you "keep insisting" it will burn unfailingly. What they told you is true.
The last one and I don't bother you anymore. If I put a circuit breaker, do I avoid this? Are there 5 amp circuit breakers that consumes the motor? Or an engine protector I don't know.
Hello
What you are looking for is called GUARDAMOTOR
They have a dial of which the protection intensity is adjusted to the nominal motor intensity, in your case with a 4 to 6 amper motor guard you are doing well as long as the nominal intensity is within that range
