Why choose IE4
IE4 sits one efficiency class above IE3. Lower losses mean lower running costs and less heat, which matters most on large motors that run for long hours. At 96.6% full-load efficiency, the UM4C 315L-4 is rated IE4 on the manufacturer's datasheet.
Typical applications
- Pumps and fans
- Compressors
- Conveyors and material handling
- Crushers, mixers and process machinery

Which mounting do I need?
The mounting type describes how the motor is fixed in place and how the shaft connects to your equipment. Choosing the right one ensures a direct, drop-in fit.
- B3 (Foot) - bolts down through feet on the base. The most common general-purpose mounting.
- B5 (Flange) - a large machined flange with clearance holes bolts directly to your gearbox or machine face.
- B14 (Face) - a smaller spigot/face flange with tapped holes, for lighter direct-coupled loads.
- B35 / B34 - combination mountings that provide both feet and a flange for extra support.
Still not sure? Message an engineer with your machine or existing motor's frame and we'll confirm the exact mounting for you.
