Cliffs Notes

Cleveland company known for steel is making high frequency motors


Cleveland-Cliffs Inc., one of the largest flat-rolled steel producers in North America, is introducing a new product line of non-oriented electrical steels for high frequency motors and generators in the North American market, the company announced Tuesday.


The new line is called "MOTOR-MAX"—all caps is still trending— and will include High Frequency Non-Oriented Electrical Steels (HF NOES) brand of electrical steels, which are designed for high speed motors, electric vehicle (EV) traction motors, aircraft generators and other rotating equipment, Cliffs said, while adding that the company's capabilities and history should position it well for the expected EV wave:


"The drive towards vehicle electrification has transformed the automotive market with the adoption of electric vehicles (EVs). As demand for electrical steels increase for EV traction motors, Cleveland-Cliffs is at the forefront of this market as the only producer of automotive-quality electrical steels in North America."


Founded in 1847 as a mine operator, Cliffs says it also is the largest manufacturer of iron ore pellets in North America. Headquartered in Cleveland, Ohio, Cleveland-Cliffs employs approximately 27,000 people across its operations in the United States and Canada.


The MOTOR-MAX High Frequency electrical steels will aim to improve the overall efficiency and performance of the motor, while also hoping to play a role in the charging station infrastructure with its grain-oriented electrical steels.


The company maintains control over the entire production cycle, using U.S.-sourced materials, incorporating recycling and other environmentally friendly sustainable practices. Cleveland-Cliffs’ technique to produce electrical steels, like MOTOR-MAX HF NOES, results in lower greenhouse gas emissions than other steel mills utilizing carbon-intensive energy sources and production methods, according to an accompanying press release.
