2.1.1 Application
MG motors can be used within the framework of IEC 60034.
2.2 Identification
2.2.1 Nameplate
The motor has two nameplates:
•
nameplate with electrical data (50 and 60 Hz)
•
nameplate with mechanical data (irrespective of frequency).
The nameplates are positioned on the side of the motor.
2.2.2 Type key
Both 50 and 60 Hz data are indicated on the nameplates
for three-phase motors.
Only 50 or 60 Hz data are indicated on the nameplates for
single-phase motors.
Only 60 Hz data are indicated on previous versions of MG
motors.
The type designation is stated on the nameplate.
