SEW EURODRIVE motor DFT100LS4 is a reliable and adaptable three-phase asynchronous motor. The following introduces its parameter characteristics, technical advantages, typical applications, and selection suggestions:

Rated speed 1720 RPM
The motor operates at nearly synchronous speed (1800 RPM) under a 60Hz power supply, meeting the design standards for 4-pole motors. It has high speed stability and is suitable for industrial scenarios that are sensitive to speed fluctuations, such as precision conveying and constant speed mixing.
3HP power output
With a rated power of approximately 2.24 kilowatts, it can drive medium load equipment such as fans and small compressors, meeting the needs of conventional industrial automation.
Dual voltage support (230/460V-AC)
By switching the wiring method (such as star/triangle), it can adapt to different regional power grid standards and reduce equipment deployment costs.

2. Technical advantages

Efficient and energy-saving design
Adopting cold-rolled silicon steel sheets and optimized electromagnetic solutions, in compliance with international energy efficiency standards (such as IE3), reducing no-load losses and improving long-term operational economy.
High protection level (IP55)
Outstanding dust and waterproof capabilities, suitable for harsh environments with high dust and humidity (such as mines and building material production lines).
Modular structure
Supports various methods such as flange installation (B3) and foot mount installation (B5), and can be seamlessly integrated with SEW reducers and frequency converters to shorten equipment debugging cycles.
low noise bearing
Choose long-life, low vibration bearings to reduce equipment maintenance frequency, suitable for noise sensitive occasions such as food processing and pharmaceutical production.

3. Typical application scenarios

Material conveying system
Drive conveyor belts and chain conveyors to achieve efficient and stable transportation of materials.
Ventilation and air conditioning equipment
Suitable for industrial fans and cooling towers, providing reliable air volume regulation capability.
Light Industry Manufacturing Equipment
Used for mixers and packaging machinery to meet constant torque load requirements.
Pump loads
Drive small water pumps and circulation pumps to optimize energy efficiency.

4. Selection and usage suggestions

Load Matching
The power margin should be selected based on the load characteristics (constant torque/variable torque) to avoid long-term overload operation. For example, a mixer that frequently starts and stops needs to reserve more than 1.2 times the power.
Power adapter
230V is suitable for single-phase power supply renovation or small power equipment, and the fluctuation range of the grid voltage needs to be confirmed (± 5%).
460V is suitable for North American standard industrial power grids, and attention should be paid to the voltage labeling of the motor junction box.
environmental enrichment
High temperature environments (>40 ℃) require the installation of independent fans or the use of forced air cooling motors.
It is recommended to upgrade to IP66 protection level for corrosive environments and use stainless steel shafts or anti-corrosion coatings.
Maintenance strategy
Check the lubrication status of the bearings every 6 months and replenish lithium based grease lubricant.
Use an infrared thermometer to monitor the temperature rise of the motor, ensuring that it does not exceed the allowable F-level insulation value (155 ℃).

5. Competitor comparison and advantages

Comparison with similar products from ABB and Siemens
SEW DFT100LS4 has more advantages in modular design, and its "three in one" solution of motor, reducer, and frequency converter can reduce installation space by more than 20%, especially suitable for compact equipment.
Cost effectiveness advantage
At the same power, SEW motors are priced 10% to 15% lower than other brands.
Industry adaptability
For the logistics industry, SEW provides customized motor encoder interfaces that can be directly integrated with automated sorting systems, reducing PLC programming complexity.

SEW motors are usually used in conjunction with reducers, forming an efficient and reliable combination in industrial drive systems. The advantages, application scenarios, and selection points of their matching use are as follows:

1, Advantages of complementary use

Modular design, flexible adaptation
SEW provides integrated solutions for motors and reducers, supporting various forms such as flange installation and coaxial installation, adapting to different mechanical structure requirements, reducing intermediate transmission components, and improving system integration.
Efficient transmission, energy-saving and consumption reducing
The motor and reducer are meshed with precision gears (such as cycloidal pinwheels, cylindrical gears, etc.), and the transmission efficiency can reach over 95%, reducing energy consumption.
Typical case: SEW's MOVIGEAR in Rotk ä ppchen sparkling wine production line ® The combination of electromechanical drive unit and reducer reduces the energy consumption of the filling line by 50%.
Enhance load capacity and protect equipment
The reducer reduces the speed and increases the torque to make the motor output more suitable for heavy load conditions (such as metallurgical and mining equipment), while reducing the damage of impact loads to the motor and extending the service life of the equipment.
Simplify maintenance and reduce costs
Modular design facilitates quick replacement of motors or reducers, reducing downtime.
Shared lubrication systems (such as splash lubrication) reduce maintenance complexity.

2, Typical application scenarios

Logistics conveying system
The combination of motor and reducer drives the drum conveyor line, achieving low-speed and high torque output, suitable for heavy-duty cargo transportation.
Case: SEW provided a 75kW motor and industrial gearbox for the Scharnebeck ship lift, lifting 11800 tons of ship containers and maintaining high reliability for over 35 years of operation.
Food and Packaging Industry
The motor and reducer drive the mixer, filling machine, etc., meeting the requirements of high cleanliness (such as hygienic design surfaces) and low noise.
Case: After adopting SEW drive technology, Rotk ä ppchen reduced the noise of the conveying system by 1.5dB, meeting the strict standards of the food industry.
Metallurgical and mining equipment
The combination of motor and reducer drives crushers, ball mills, etc., and can withstand high overload and impact loads.
Features: SEW reducer has strong load-bearing capacity, stable torque output, and is suitable for harsh working conditions.
New energy and environmental protection equipment
Electric motors and reducers are used in wind turbine pitch systems, sewage treatment mixers, etc. to achieve precise control and efficient transmission.

3, Key selection points

Matching power and speed
Select the motor power according to the load requirements (such as 3HP suitable for medium loads), and the gear ratio of the reducer should ensure that the output speed meets the process requirements (such as a 1720RPM motor outputting 100-500RPM after deceleration).
Installation method and space limitations
Priority should be given to using coaxial reducers (such as SEW R series) for compact equipment to reduce axial dimensions; When there is ample space, expandable or split type reducers can be selected for easy maintenance.
Environmental adaptability
IP66 protection level motors and stainless steel reducers should be selected for humid and corrosive environments; High temperature environments require enhanced heat dissipation (such as external fans or water cooling).
Energy Efficiency and Certification
Prioritize the use of IE3/IE4 energy efficiency level motors to reduce long-term operating costs; The food industry must comply with FDA or EU hygiene standards.
