ABB has expanded its SP4 motor lineup with new models featuring integrated shaft grounding, designed to provide advanced bearing protection in variable speed drive (VSD) environments. This new range aims to help customers reduce maintenance costs, extend motor life, and improve efficiency by up to 20%. The SP4 motors are built on a trusted design and offer high efficiency and superior protection in a rolled steel frame, an industry-first combination.
The new models feature a built-in shaft grounding ring that provides critical protection for motor bearings, preventing harmful electrical discharge and reducing bearing wear. This design also delivers high-efficiency performance, meeting NEMA Super Premium (IE4) standards without relying on magnets or rare-earth materials. The motors are available in 2, 4, and 6-pole designs, with models ranging from 1 to 10 HP (TEFC) and 1 to 20 HP (ODP), and are backed by a four-year warranty.
The SP4 series is ideal for industries that rely heavily on VSD-driven equipment, such as HVAC systems, water treatment plants, and manufacturing facilities. The motors are designed to meet the demands of modern industry, with applications in fans, pumps, compressors, and conveyors across various sectors. With over 300 million motor-driven systems operating worldwide, high-efficiency solutions like the SP4 range play a crucial role in lowering energy costs and reducing environmental impact.
ABB’s expansion of the SP4 motor lineup marks the fourth phase of the platform, continuing the company’s drive to offer reliable, energy-saving motor technology. The company supports the shift towards sustainability through product innovation, circular design principles, and investment in long-term solutions that promote reuse, recycling, and reduced waste. As a global technology company, ABB is committed to driving innovation and industrial transformation, with a focus on advancing electrification and automation to create a more sustainable future.
The SP4 motors eliminate the need to choose between efficiency and bearing protection, providing a cost-effective and reliable upgrade path for users. The design reduces energy losses by an average of 20% compared to traditional motors, even when operating as standalone DOL units, and achieves greater benefits when paired with VSDs. With its commitment to sustainability and innovation, ABB is well-positioned to support the growing demand for energy-efficient solutions and contribute to a more sustainable future.
