New features in STOBER’s 3HP cLEAN Motor: More power, more control, more flexibility

Harsh washdowns, tight machine envelopes, and increasing safety & control requirements continue to push food and beverage equipment to do more—without compromising hygiene. STOBER’s cLEAN System has long been trusted for its stainless steel construction, zero weep-hole design, and proven resistance to water ingress. Now, that trusted platform takes a significant step forward.

With the release of the 3HP cLEAN Motor, STOBER delivers more power for demanding applications and introduces new configuration and control options that expand how and where the cLEAN System can be used. These additions include a right-angle motor configuration, an optional power-off brake, and expanded feedback device options, including resolver and encoder support.

Below is a closer look at what’s new and why it matters in washdown-heavy applications.

Right-angle configuration: designed for tight spaces and smarter cable routing

One of the most impactful updates in the 3 hp cLEAN Motor is the availability of a right-angle configuration. This option is ideal for equipment where space is limited or where traditional inline motors create installation or sanitation challenges.

Why right-angle matters in hygienic design

In many food processing and packaging machines, space constraints force designers to compromise, often adding guards, offsets, or complex mounting structures. The right-angle cLEAN Motor allows the drive package to fit cleanly within the machine footprint while maintaining STOBER’s fully stainless steel, washdown-safe construction.

Key benefits include:

• A smaller overall footprint for compact machines and retrofits
• Improved cable exit orientation to reduce stress on cables and connectors
• Cleaner machine layouts with fewer obstruction points for sanitation crews

Because the right-angle option is fully integrated into the cLEAN System, it maintains the same IP68/IP69K protection, zero weep-hole design, and EHEDG-aligned hygienic principles as inline versions without introducing new ingress risks.

Power-off brake (right-angle only): built-in safety for inclines and hold loads

The 3 HP cLEAN Motor also introduces an optional power-off brake, available exclusively with the right-angle configuration. This feature is designed for applications where controlled stopping and load holding are critical, especially in vertical or inclined systems.

What makes the power-off brake different?

STOBER’s power-off brake is a 24V, 15Nm brake that engages automatically when power is removed. This ensures the motor shaft is securely held during:

• Power loss or emergency stops
• Planned shutdowns
• Maintenance and cleaning procedures

Typical applications include:

• Incline and decline conveyors
• Lifts and vertical positioning systems
• Safety-critical material handling equipment

Because the brake is integrated directly into the motor design, there is no need for external braking hardware. This helps maintain a clean, sealed system while reducing installation complexity. Like the rest of the cLEAN System, the brake is engineered to withstand frequent high-pressure washdowns without sacrificing reliability.

Expanded feedback options: resolver and encoder support for smarter control

As automation strategies continue to evolve, many applications require more than basic speed control. To support advanced motion control, diagnostics, and system integration, the 3HP cLEAN Motor now offers expanded feedback options, including resolver and encoder configurations.

Resolver feedback: rugged and washdown ready

Resolvers are well suited for harsh environments where temperature extremes, vibration, and moisture are common. In washdown applications, resolver feedback provides reliable motor position and speed data while maintaining compatibility with the cLEAN Drive.

Resolver advantages include:

• High resistance to moisture and contamination
• Reliable operation across wide temperature ranges
• Long-distance signal transmission

Encoder feedback: higher precision and system insight

For applications that require greater precision or deeper system visibility, encoder feedback is also available. Encoders enable:

• Improved speed regulation
• Enhanced diagnostics and monitoring
• Easier integration with PLCs and advanced control strategies

By offering both resolver and encoder options, STOBER allows engineers to match the feedback device to the application without compromising hygienic design.

More power without compromise

All of these new features are built on the foundation that made the cLEAN System a trusted solution in washdown environments. The 3 hp cLEAN Motor continues to deliver:

• All-stainless steel construction
• IP68/IP69K and UL certifications
• Zero weep holes and redundant sealing
• IE5 permanent-magnet efficiency
• Full system coverage under STOBER’s three-year warranty

The result is more power, more control, and more flexibility without sacrificing hygiene or reliability.
