Everything you need to know about stainless steel electric motors

What is a stainless steel electric motor?

A stainless steel motor is an electric motor with a housing made of stainless steel AISI 304 or AISI 316, not from painted cast iron. All BEGE stainless steel motors have a smooth surface and IP69K protection, so they withstand high-pressure high-temperature wash-downs. Smooth housing means there are no edges or seam lines where bacteria and residues can accumulate. This design is standard in all stainless steel motor series offered by BEGE.

What are the primary benefits of stainless steel electric motors?

Stainless steel electric motors are designed for hygienic and corrosive environments. A smooth, seamless housing helps prevent accumulation of residues and bacteria, while corrosion-resistant material helps prevent rust in humid, salty or chemical environments. With IP69K protection, they can withstand high-pressure, high-temperature wash-downs without water entering the housing.

What is IP69K protection? Why is it needed for stainless steel electric motors?

IP69K is the highest degree of protection from dust ingress and from high-pressure and high-temperature water streams. A motor with IP69K rating can withstand close-range washdowns at high water pressure and temperature without water entering the housing.

BEGE stainless steel motors have IP69K rating as standard. This is vital for equipment that undergoes daily cleaning processes such as conveyors and mixers in food factories. Without this rating, wash-downs will negatively affect performance of standard motors due to corrosion and malfunctioning of internal parts.

Where are BEGE stainless steel motors commonly used?

BEGE stainless steel motors are used in several sectors such as food and beverages, chemical processing, pharmaceutical manufacturing, water treatment plants and marine applications.

In food processing industries BEGE motors drive conveyors, mixers and packaging machinery with frequent wash-downs. In the maritime industry BEGE motors provide power to pumps, winches and fans that are exposed to salt water. Chemical and pharmaceutical plants rely on the same corrosion resistance to keep pumps and mixers running reliably in aggressive environments, while water treatment plants use the motors’ IP69K rating to handle constant humidity.

How do stainless steel electric motors compare to standard painted electric motors?

Standard painted motors are less expensive at the beginning, however, rust faster upon exposure to moisture, salt or cleaning chemicals, as they easily chip off the paint. BEGE stainless steel motors do not have this drawback, as their housing material itself is corrosion resistant, not the painted coating.

BEGE stainless steel motors are designed for highly corrosive and sanitary environments, which makes the motors a better fit than painted alternatives wherever washdowns, salt water, or aggressive chemicals are part of daily operation.

Standard motors are generally not certified for the hygiene standards required in food and pharmaceutical production, while BEGE stainless steel motors comply with HACCP and IP69K standards. Due to higher upfront costs, stainless steel motors are usually more economical in terms of total ownership costs when they will be used for applications involving wash-downs, humidity and chemical exposure.

What to consider when choosing a stainless steel electric motor?

Selecting the right stainless steel electric motor starts with matching power range and IEC motor size to the application, since BEGE’s five series cover different combinations from 0.18 kW up to 22 kW. Next, check the required efficiency class: BEGE’s BGX and EBS series meet IE3 and IE4 standards, which matters for energy costs and regulatory compliance in the EU.

Consider whether a built-in brake is needed, since the EBS Brake series adds this feature with a side-mounted terminal box for safety and hygiene. Last step is choosing the stainless steel grade required for the environment: AISI 304 suits most food-safe applications, while AISI 316 is built for more extreme or corrosive conditions, as used in the KBS series.

Are BEGE stainless steel motors food safe?

Yes, BEGE stainless steel motors are designed for food safety and comply with HACCP requirements. The smooth, seamless AISI 304 or AISI 316 housing prevents bacteria growth at seams and ledges, which is a typical problem for painted motors. This hygienic design withstands high-pressure cleaning without degradation. This design helps food production companies maintain their hygiene schedule.

Can stainless steel electric motors be customized?

Yes. BEGE stainless steel motors can be custom-made in addition to standard series. Most frequent customizations are encapsulated winding, electronic brake, pressure relief valve, special voltage, custom flange, anti-condensation heater and IP69K cable glands.

With customizations you can adapt motor to particular application needs. BEGE engineering team takes care of quality control of custom motors in their headquarters in the Netherlands.

What energy efficiency classes do BEGE stainless steel motors meet?

BEGE stainless steel BGX series complies with IE3 and IE4 energy efficiency classes. EBS series reach IE3 and IE4 efficiency classes according to configuration. High efficiency decreases electricity costs during motor lifecycle. Therefore, IE4 rated motor from BEGE’s BGX series helps you save money and stay in compliance with European regulations.
