M Line motors are manufactured in different configurations in reference to cooling methods and degree of protection. As a result, a motor configuration can be defined in such a way to better meet operating and environment conditions.
Motor supplied in frame sizes IEC 280 to 450 (NEMA 4400 to 8000) are manufactured in cast iron frames.
Those motors manufactured in frame sizes IEC 500 (NEMA 8800) and larger have their frames built in welded steel plates.
Main advantages in using WEG M Line motors include:
- High efficiency
- Degree of Protection IP23 (WP-I), IP(W)24 (WP-II) or IP(W)55 / IP(W)56 / IP(W)65
- Reduced noise level
- Low and easy maintenance
- Can be built to meet API 541 standards
- Squirrel cage rotor
Slip ring (wound rotor)
- Bearings
Oil lubricated sleeve bearings
Grease or oil lubricated ball or roller bearings
- Interchangeability with existing motors.
