motor information.

[charrid]

I have some doubt about information that are on motor plate,

1- What means; Duty : SI.
RISE: 80 K
IP : 55
IC : 411

80K I presume is the temperature rise at rated load. Usually in degrees C, but K is equivalent to C when examining differences (rises).

IP55 is the degree of ingress protection. The first 5 means dust-protected. The second 5 means protected against water jets.

IC411 is the cooling. First 4 means frame or surface cooled. I think the first 1 means that the internal air flow is dependent on machine speed. The second 1 means the external air flow is also dependent on machine speed. In other words, I think this is totally enclosed fan cooled. Two fans... one for internal circulation and one for external.

Duty: SI - I'm not sure whether this might be inverter or intermittent?

thank you very much!but now i need more information.
what is:
4EC1

this one is a ABB motor
KL : 20682 1
a design 6309z/c3

Suggestions:
1. Contact ABB Rep. since 4EC1 may be a model, type, etc.
2. SI may stand for short-intermittent duty. Also, check with ABB Rep.
