More Help Please

Marvo · Oct 9, 2014

Thanks for the assistance I've received so far in the trainee forum, much appreciated.

I have another question though and this time it's about a motor I have. On the motor is an info plate and there's a whole load of numbers and letters on it, I'd appreciate some help deciphering what the hell it all means.

Here's a list of the gibberish on the plate;

Ph ; 3
V ; 400v
FLA ; 3.55A
LRA ; 7.8A
COSφ @ FLA; 0.87
EFF2
ENCL ; TEAO IC48
Freq ; 50Hz
r·min−1 ; 1450
AMB ; 40C
Duty ; S1
HP ; 2
INS Cl ; B
Alt ; 1000m
SF ; 1.2
Mnt ; B3

Maybe the trainees can do the copy/paste thing and write explanations next to each one please.

Here's a list of the gibberish on the plate;

Ph ; 3 - Three phase motor.
V ; 400v - Voltage rating.
FLA ; 3.55A - Full load amps.
LRA ; 7.8 - Locked rotor amps.
COSφ @ FLA; 0.87 - Power factor @ full load amps.
EFF2 - Efficiency ?
ENCL ; TEAO IC48
Freq ; 50Hz - Frequency
r·min−1 ; 1450 - RPM
AMB ; 40C - Ambient temperature
Duty ; S1
HP ; 2 -.Horse power
INS Cl ; B
Alt ; 1000m
SF ; 1.2
Mnt ; B3

Not so good with this one. Hopefully i am not far off.

After wrapping up my last thread in three replies this one should be a little more difficult and may even require a bit of Googling

Very valiant attempt Simon, the efficiency is expressed as an efficiency class and in this case the motor is EFF class2. The ambient temp shows the maximum surrounding air temperature allowed. If anyone else has any suggestions please feel free to shout.
