Explore the key features and benefits

ABB’s SP4 technology meets the NEMA Premium 4 efficiency level in a standard AC induction motor design operating across the line, independently of a variable speed drive.*

Large install base

There are more than 300 million industrial motor-driven systems in operation worldwide; and roughly 80% of motors still operate DOL (direct on line).

Lower energy costs

NEMA Super Premium® (comparable to IEC’s IE4 efficiency) can offer up to 40% lower energy loss in comparison with a NEMA standard efficient (IE2) induction motor.

Cooler running

Able to achieve cooler running operation for longer life which means longer bearing life. This translates to longer motor life and industry-leading 4-year warranty.

Inverter Duty

Suitable for inverter use per NEMA MG1 Part 31.4.4.2

Drop-in Design

Shortcut your energy savings with an easy drop-in design to your existing motor

Shaft grounding

Internally mounted shaft grounding ring provides enhanced bearing protection and peace of mind in inverter-driven applications.
