We are working with Magnomatics
For two decades—nearly since the company’s inception—we have proudly partnered with Magnomatics, watching them evolve into one of the UK’s most innovative and exciting engineering firms.
Magnomatics specialises in the design, development, and manufacture of advanced magnetically geared transmission systems and high-torque magnetically geared motors.
In our latest presentation video for Magnomatics, the presenter breaks down the mechanical principles, operational advantages, and real-world applications of these groundbreaking drive systems.
How Magnetic Gear Transmission Systems Work
Unlike traditional mechanical gearboxes that rely on meshing physical teeth, magnetic gears transmit torque seamlessly through magnetic fields.
- Contactless Transmission: Utilizing an inner and outer ring of magnetic elements paired with central steel pole pieces, the system operates completely without physical contact.
- Zero Friction & Wear: By eliminating mechanical friction, these systems drastically reduce wear, energy loss, and maintenance requirements while boosting operational efficiency.
- Built-in Overload Protection: The contactless architecture acts as a natural torque fuse. Under extreme overload conditions, the magnetic coupling safely slips without causing mechanical damage or component failure.
- Hermetically Sealed Design: Operating through solid physical barriers allows for fully sealed motors, making them ideal for high-pressure, submerged, or extreme environments.
The Pseudo Direct Drive (PDD®) Advantage
A key highlight of the presentation is the Pseudo Direct Drive (PDD®) configuration. By combining a high-ratio magnetic gear directly with an electric motor, the PDD® delivers exceptionally high torque and power density in a compact, efficient package.
- Unmatched Efficiency & Reliability: Fewer moving parts and zero mechanical contact mean longer operational lifespans and minimal servicing.
- Submersible & Harsh Environment Ready: While custom-designed for submersible craft propulsion, PDD® technology is inherently resilient in demanding settings.
- Scalable Applications: The technology scales seamlessly across industries—from subsea robotics and maritime vessels to high-altitude aerospace systems.
