[SARADR]

Hi, I have a problem. I can't understand how, from the catalog I can trace to the exact, or possibly qualitative curve of the driving feature of a three-phase asynchronous electric motor. Could you explain it to me?

In fact, if the catalogue does not show curves, and it is almost always so, you can't get what you ask, the catalogue only shows a power to a certain speed of turns.

Hi.
try to visit the manufacturer's website. are usually published.

for example the builder marelli has them:

Hello Saradr, I see you haven't introduced yet, I invite you to do it as soon as possible and read qui e Who..

hello saradr, each electric motor has its application curve and varies strongly with the type of construction technology/principle of operation (continuous current, alternating current, vector, squirrel cage, asynchronous, synchronous etc).

for three-phase alternating current engines there is the beautiful catalog of engines related to bonfiglioli, where it indicates the power/n turn curve with which you can obtain the performance of the engine you take in the catalog.

always for this category it is possible to build some true similar curves to make reasoning the quite good choices of the motors and you can build a excel sheet or more simply using the box you parameterize all the data taking into consideration the "max run" that makes change all the characteristics of the motor
