⚡ Introduction: The SEW-EURODRIVE Award for an Outstanding Research Project
The SEW-EURODRIVE Foundation is known for supporting advanced research and studies in the fields of electrical and mechanical engineering. In 2025, Sophia Koll received an award dedicated to the master’s thesis she prepared on the design of an advanced electromechanical motor without bearings.
The thesis focused on developing an adjustable bearingless motor, where this motor is used in testing magnetically suspended rotary blood pumps, which represent the future of medical devices that rely on magnetic levitation technologies to reduce friction and increase lifespan and effectiveness.
🔧 What is a bearingless motor?
A bearingless motor is a type of electric motor that avoids using traditional bearings that support the rotor. Instead, it relies on magnetic levitation forces to keep the rotor centered within the magnetic field.
- Reduced friction: The absence of mechanical bearings and contact surfaces reduces energy loss and wear.
- Greater precision: Magnetic control allows more precise control of the rotor position and speed.
- Reduced noise: Thanks to the absence of mechanical contact.
This type of motor is particularly suitable for medical applications such as blood pumps that depend on magnetic levitation technology, where reliable and sustainable operation is required with quiet performance and precise engineering.
📊 Technical aspects in the design of the adjustable motor
Designing the adjustable motor requires:
- Magnetic field analysis: Studying the distribution of magnetic force to provide stable levitation of the rotor and prevent collision with the housing.
- Control system: Programming algorithms that address centering stability and precisely control motor speed.
- Experimental performance testing: Verifying the motor’s properties through practical experiments under conditions suitable for blood pump applications.
The experiment also includes adjusting the motor’s various parameters such as electric current, voltage, and frequency to meet the operating requirements of the rotary pump.
🔹 Important point: The experimental design of the motor provides real data that helps improve theoretical models and develop more effective control systems.
🛡️ Applications of bearingless motors in electrical and medical engineering
Advances in magnetic levitation technologies within the electrical and mechanical fields make the following possible:
- Rotary blood pumps: These pumps are used in medical devices to support heart function, where magnetic levitation technology improves pump lifespan and reduces damage caused by friction and wear.
- Precise measuring and analysis devices: Bearingless motors support control and motion systems that require high accuracy and low vibration.
- Advanced mechatronic systems: From robots to industrial tools that require a small size and high performance without mechanical friction.
📐 The importance of research and innovation in electrical engineering
Improving and analyzing electric motor systems leads to:
- Higher efficiency of electrical devices: Reduced energy consumption and improved performance.
- Enhanced power quality: By reducing vibrations and electromagnetic interference.
- Development of protection and control systems: To increase reliability and safety in industrial and medical systems.
In addition, the synergy of research work between universities and research centers enhances progress in electrical and mechanical technologies in an integrated way.
⚠️ Safety warning: It is always recommended to follow protection guidelines when dealing with magnetic levitation motor systems, especially because precise control of magnetic fields requires proper mounting and tight control systems to avoid hazards.
🔄 How can students and technicians benefit from this research?
Students and technicians can learn the principles of advanced electric motors through:
- Studying magnetic levitation technology and the principles of the magnetic field.
- Learning about motor control strategies that rely on precise sensors.
- Experimenting with prototypes using electrical and mechanical simulation software.
- Learning measurement and analysis methods using devices such as Multimeter and Oscilloscope to understand real-world performance.
This helps refine mechatronic and electronic engineering skills and prepares students to enter the job market with advanced technologies.
📌 Quick summary: Innovation in bearingless motor design represents an important direction for improving medical and industrial devices, and forms a strong scientific and practical foundation for engineers specializing in electrical and mechatronic systems.
