WEG supplies permanent magnet motor to Klabin

Industrial motor manufacturer, WEG has supplied a permanent magnet motor to Klabin, the largest producer and exporter of packaging paper in Brazil. Aiming at ensuring better results for its production process, Klabin purchased a 125 HP WEG W22 Magnet motor in October 2019 to replace the DC drive of its lime furnace.

The lime furnace burns the lime mud generated in the pulp production process and turns it into lime, used in the production of white liquor, which in turn is used for cooking wood in the digester and for making pulp. As this machinery requires attention from the maintenance teams, DC motors are not usually the preferred option due to the high inertia of the load at the start and during operation.

However, the change was carried out successfully and the motor has obtained excellent performance rates.

Continuously investing in innovation, WEG's philosophy is to develop high performance products and efficient systems to offer suitable solutions to its customers. The high efficiency W22 Magnet motors have permanent magnets, thus ensuring advantages such as robustness, high performance and higher power density per frame.

Driven by WEG’s CFW11 frequency inverter, the motors provide constant torque and a wide speed range. They even operate at low speeds with efficiency levels above induction motors, without requiring forced ventilation. The W22 Magnet motor is ideal to drive paper machines, replace DC drives and solve applications where speed variation is required.

Energy efficiency cases like this, which promote the replacement of DC motors with high efficiency permanent magnet motors, prove that the return on investment makes good business sense - both in terms of financial and energy savings.

For Klabin, this acquisition enabled greater productivity due to the increase in the machine availability and the equipment energy efficiency. According to analysis made since the motor acquisition in October 2019, there has also been a reduction in energy consumption, exceeding the project expectations.

WEG is widely recognised for its energy efficiency solutions for various industrial applications. The company offers the market several combinations of high-performance products, bringing innovative technology to industrial processes worldwide and building solid relationships with large companies such as Klabin.
