Efficient Accessory Motors ft. Bonded Neo Magnets
As vehicles become more sophisticated, accessory motors play an increasingly vital role inside the cabin. These motors, which power everything from seat adjustments to tailgate lifts and sunroofs to wipers, are critical for providing the comfort and convenience modern consumers expect. The rapid growth of electric vehicles (EVs) further accelerates this trend, increasing demand for more advanced, efficient, and compact motor solutions.
Why are accessory motors crucial in vehicles?
Accessory motors are essential in modern vehicles because they automate many comfort and safety functions that were once manual. From reclining seats to window lifts, these motors ensure seamless operation with minimal driver effort. The push toward greater vehicle comfort, especially in EVs and luxury cars, has resulted in a significant uptick in the number of motors used per vehicle. For example, luxury models like the Lincoln Continental now feature 30-way adjustable seats powered by sophisticated accessory motors that offer passengers unparalleled comfort and precision control.
EVs: The Catalyst for Accessory Motor Growth.
Electric Vehicles (EVs) are leading the charge in adopting accessory motors. EVs often feature compact and efficient motor systems to conserve energy and maximize battery life. With fewer moving parts in the drivetrain, EV manufacturers focus more on enhancing the passenger experience inside the cabin. Advanced seating systems, tailgate motors, and other powered functions are becoming standard in luxury models and mainstream cars. This demand for space-efficient, high-performance accessory motors drives significant growth and presents new opportunities for magnet suppliers to deliver cost-effective solutions.
The Role of BLDC Motors and Safety Enhancements
Brushless DC motors (BLDC) are also used in accessory motors. Due to their high efficiency and longer lifespan, BLDC motors are becoming increasingly popular in electric and luxury vehicles. One of their most important advantages is their ability to enhance safety features within the vehicle.
BLDC motors are highly compatible with autonomous systems and advanced driver-assistance systems (ADAS), which require precise control and minimal electromagnetic interference (EMI). Their enhanced electromagnetic compatibility (EMC) significantly reduces EMI, which is crucial for functioning safety-critical systems like automatic seat positioning during emergencies, smart window systems, and collision avoidance systems. Magnet suppliers, particularly those developing bonded neodymium magnets, make these BLDC motors efficient and compact.

Supplier Perspectives: How the Magnet Market Benefits
Motors rely heavily on magnets, and as the demand for motors grows, so does the need for cost-optimized magnet solutions. Magnequench 's bonded neo magnets, with their low rare earth content, offer a cost-effective alternative to traditional high-end ferrite magnets without compromising on performance. These magnets are ideally suited for space-constrained applications like seat adjustments, side door drives, tailgate motors, and many more, offering high performance in smaller form factors. Magnequench Neo Performance Materials , a leading supplier of bonded magnets, has developed competitive bonded magnet assemblies that deliver the ideal solutions for the growing demands of the accessory motors in a vehicle.
Innovation Through Collaboration: The Power of Integration
The future of accessory motor innovation lies in collaboration across the value chain. Magnet suppliers can work closely with motor manufacturers (1/2 tier suppliers) to develop joint roadmaps that align development timelines and reduce costs through economies of scale. This collaborative approach ensures that each component—magnets, plastic gears, and motors—is optimized for both cost and performance, ultimately delivering better solutions to the market.
For example, one promising innovation is the One-Motor Power Seat Structure, which simplifies motor configuration by integrating multiple functionalities into a single motor. This approach allows smaller cars to have advanced features once reserved for premium models. Such innovations open new market opportunities for seat motors and other accessory systems and highlight the growing importance of cost-effective, space-efficient magnets in automotive design.
The Future: Autonomous Driving and the Role of Accessory Motors
As we move toward fully autonomous vehicles, the role of accessory motors will expand even further. Cabin comfort will become a key differentiator as passengers in fully autonomous cars shift their attention from driving to relaxation and productivity. Motors powered by energy-efficient bonded neo magnets will enable manufacturers to deliver customizable in-cabin experiences while improving safety through seamless integration with ADAS and other autonomous systems.
The dream of fully autonomous driving will depend on value chain partners collaborating to deliver cutting-edge solutions for in-cabin comfort while maintaining a net-zero carbon footprint. By working collaboratively, motor makers and magnet suppliers like Magnequench can significantly contribute to the industry's long-term goals, including carbon-neutral vehicles and enhanced passenger safety.
The future is bright for suppliers who embrace innovation and partnership in this dynamic and growing market.
