ABB’s new stainless steel encapsulated motor is ideal for washdown applications

2016-11-16 - New IEC stainless steel encapsulated (SSE) motor is targeted at washdown applications in the food and beverage industry and is compatible with clean-in-place (CIP) methods. It withstands high pressure sprays for maximum hygiene, and offers superior reliability and efficiency to reduce downtime and save energy.

ABB, the leading power and automation technology group, has launched a new IEC stainless steel encapsulated motor for washdown environments. The motor has a number of features that enable it to be easily and effectively cleaned to maximize food safety. IP69K ingress protection stands up to close-range spaying with hot water (80oC) at pressures up to 100 bar. The TENV (totally enclosed, non-ventilated) design means the external surfaces are smooth and self-draining, with no crevices where contaminants could collect. The markings are laser engraved on to the frame, a more hygienic solution than a regular nameplate, and H1 food-grade grease is used.

With its high ingress protection level and fully encapsulated windings, the motor can last much longer than a standard product in tough, humid conditions. Longer motor lifetimes mean less downtime, reducing maintenance costs and keeping production running consistently.

The motor is available in efficiency levels ranging from premium efficiency, IE3, up to IE5 (with variable speed drive control). High efficiency not only saves energy but also means lower running temperatures, another factor that that creates reliability.

“Up to now many plants use standard motors in washdown areas. They are fitted with shrouds to protect against high pressure washing, but it’s impossible to clean them properly because they are not designed according to hygienic principles. They also don’t last very long in harsh conditions. Our new motors are designed for easy sanitization and engineered for reliability and efficiency,” says Tero Helpiö, Industry Segment Manager – Food and Beverage, ABB IEC low voltage motors.

“ABB’s unit in the US, Baldor Electric Company, has been supplying Baldor-Reliance NEMA standard stainless steel motors to the food industry for more than two decades. Now we’re making the same technology available for the IEC market. In addition to end users, these motors are a great choice for OEMs based in Europe and Asia - the availability of 50 and 60 Hz, and compliance with different MEPS (Minimum Energy Performance Standards) around the world, supports OEMs to serve their customers in both their domestic and export markets easily.”

The motors are initially available in the power range 0.37–1.5 kW, with higher powers up to 7.5 kW coming in 2017. They are available in 2–6 pole versions for 230–690 V at 50 Hz, or 60 Hz with UL certification. Flexible mounting arrangements (B14, B5, B3) ensure they will fit almost any application.

“By specifying ABB stainless steel encapsulated motors for their equipment, plants will enhance food safety of their products and improve their total cost of ownership,” Tero Helpiö states.

ABB (ABBN: SIX Swiss Ex) is a pioneering technology leader in electrification products, robotics and motion, industrial automation and power grids, serving customers in utilities, industry and transport & infrastructure globally. Continuing more than a 125-year history of innovation, ABB today is writing the future of industrial digitalization and driving the Energy and Fourth Industrial Revolutions.
