    Triphase motor connection

    Hi RedSnake, This is a good answer for me. Then, what about VFD drives. In a drive you can enter both the tension and the current. Does this mean that, generally, you can supply different values of tension and different values of current as you want?? I know that opening the issue of drives...

    Triphase motor connection

    Hi che12345, 1. The standard EU LV is 230-400V (50Hz). In Spain ? It is unlikely? that you have 400-690V from the utilities, but you may have it in your own installation. It should be understood that 230-400V means that any Line to the Neutral is 230V and any Line to Line is 400V. A 400-690V...

    Triphase motor connection

    Hi edison123, If I have a Δ230-Y400, does this mean that the coils are thermal protected for 230V?? Is that right?? Then, if I connect this motor to a 230-400V electric gird in triangle, I will burn the motor!! Each coil is receiving 400V!!

    Triphase motor connection

    Hey there, I'm from Spain, so the threephasic system we have here is 230-400V and 400-690V for industrial purposes. If I have a Δ230-Y400 motor and I want to connect it to the 230-400V, I suppose that the only way is in star connection. As far as I know, the coils are prepared for 230V between...

    Cocentricity verification

    Hi Johnny, If I have understood you well, the way is to put your reference to the shaft by attaching the dial on it so your measurement will be the relative between the shaft and the bore. I expect to have Ø25, Ø35 and Ø45 on my shafts so, is there any clamping accessory directly able for these...

    Cocentricity verification

    Hi Mr. Pellin, You have completely understand my question, that's great. I like your first answer. But I don't know which type of dials exist. is there a dial able to measure bore concentricity?? Can you post some picture or redirect to somewhere?? It's difficult to find information of that...

    Cocentricity verification

    Hey there, My question is very simple. Which would be the phisical procedure to validate/measure the concentricity of a shaft into a hub like the ones of the picture: As it can be seen, I can't use the external cylindric wall of the hub because it is conical and, let's say, it has a low...

    Dynamic analisys with ANSYS

    Hello, would somebody of you explain me if I can manipulate a valve insitu in an Ansys simulation? I don't know anything about ANSYS Workbench. I would like to make a pump proof to extract the curve but virtually, and I don't know how can I do this with ANSYS. Maybe I have to preprogram the...
