motor information.

motor information.

motor information.

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

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

RE: motor information.

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?

RE: motor information.

(OP)

2. SI may stand for short-intermittent duty. Also, check with ABB Rep.
