Severe Duty motors
For the most demanding applications

3—
Safety in the most extreme
environments

We know your business operates in challenging
environments and difficult conditions. Your needfor a reliable, easy to use and maintain and durable
motor is more crucial than ever.
Baldor-Reliance® Severe Duty motors from ABB are
designed to provide exceptional performance andlong life in harsh industrial processing applications.
A few typical applications which might require
these types of motors include petrochemicalplants, mines, foundries, pulp and paper plants,
waste management facilities, rock crushers, andchemical plants.
These motors use Super-E® premium efficientelectrical designs which are built to handle
demanding duty cycles, provide high starting andpeak torques, and operate over wide speed ranges.

Severe Duty motors provide safe, long operating
life, reliable performance, and reduced energy
consumption in the toughest applications.
Baldor-Reliance Severe Duty motors have three
guiding principles behind each design:
1. Safer installation:• Rugged lifting provisions (1)• Oversized conduit box
2. Safer connection:• Clamp type grounding lug• Permanently labeled color leads
3. Safer operation:• Division 2 for hazardous locations• Lead separators on all severe duty ratings protect
against shorts and abrasion of power leads• ABB AbilityTM smart sensor for motors provides
touch-free condition monitoring

S E V E R E D U T Y M OTO R S—Demanding applications

Severe Duty motors are installed in the most demanding applications. Rain or shine, these motors areexpected to run to peak performance without disruptions. Baldor-Reliance Severe Duty motors offer
protection from contaminants as small as dust particles that can get into small crevices and can damage
the electrical components inside the motor. The rugged cast iron design also protects from falling debris
often seen in harsh applications. These motors are capable of withstanding extreme low and hightemperatures and will operate in high altitude where the air is thinner or at sea level conditions where salt
corrosion eats up the equipment.

Challenges to overcome

Reliability
Equipment and motor are exposed to the open environment, rain or shine. They need tobe protected against contaminants such as rocks, gravel and dust frequently contact
the motor.
Easy
Customization for the application and considering all the NEMA mounting options canbe tough to find a “one size fits all”.

SafetyFrom the installation process to operating process – these motors are used in unsafeenvironments.

Our solution
The Baldor-Reliance Severe Duty motors are capable of handling it all. Selecting theright motor will increase your operation’s reliability, easy to select and install, and safeto operate.

Extended reliability
Performance and protection from any
application
Rugged, durable motor construction protects rotating and electrical components to provide extended
operating life in industrial applications prone to dusty, dirty, wet, outdoor, and potentially highvibration environments.
Severe Duty motors are suited for normal torque applications in harsh industrial environments wherereliability and highest operating efficiency is desired, and they are built with heavy-duty cast-iron
enclosure and regreasable bearings to maximize the life of the motor. The entire Severe Duty line
harnesses a feature-rich philosophy that is standard on all frame sizes of the product family.

7—It's all in the details
15 ways we designed Severe Duty
differently
1. All-cast iron construction for longer lifeacross all frame sizes

2. 1.15 service factor on across-the-line
power. 1.25 service factor for Crusher Duty up
to 100HP.

3. Conduit box, oversized and in cast iron,provides for an easy and reliable installation
process.

4. Foot flatness for better alignment andbalance, easier install, and increased
reliability

5. IP55 rating to protect from harsh duty
environment

6. Gaskets are premium lead separators which
prevent friction and abrasion between theleads which eliminates electrical shorts andfailures for enhanced safety operations

7. Colored leads, which are permanently
labeled and numbered, provide two factor
identification for easier and safer
connections

9. Vertical jacking provisions make the difficult andcritical task of aligning the motor a lot easier. It allows
the installer to micro-adjust the final and criticaladjustments required to ensure the motor’s shaft isaligned to perfection, which ensures the motor
performs to its prime.

10. Dowel pin holes speed up the maintenance process.
Users are able to drill their base using dowel pins. So
when the motor needs to be taken out for regular
maintenance, the installation process is a breeze.

11. Embossed stainless steel nameplate ensures thatsensitive and sometimes critical information isavailable when it is needed the most.

12. 60/50 Hz information is available on the nameplate.
This is a feature much anticipated and requested bymost OEMs.

13. Connection diagrams are easy to find and ensure asafe and easier connection.

14. Inverter data is standard on all stock product. This
gives the customer greater flexibility by allowing
operation on across-the-line power or paired with aVFD.

15. For our larger frame sizes, we provide enhanced
lifting provisions that are cast-in for added safety
8. Grounding lugs located on the foot of themotor and in the conduit box for a safer andeasier installation.
