Admotec Precision Transformers for High Speed Motors

　　The Craftsmanship Path of Transformers (Rotary Transformers) in the High Speed Motor Field of Admotec Precision, Switzerland

From the R&D laboratory in Zurich, Switzerland to the core control unit of high-speed motors, Admotec Precision has been deeply rooted in technology for nearly 40 years, and has embarked on a production evolution path of "precise adaptation, extreme breakthroughs, and scenario empowerment". As a Swiss company specializing in motion sensing and energy transmission solutions, its transformers (core of which is rotary transformers) have become key supporting components for high-speed motors in aerospace, industrial automation, automotive and other fields due to their adaptability to high-speed working conditions, witnessing and promoting technological iteration in the industry.

Start up exploration: anchoring high-speed pain points and laying the technological foundation (1987-2000)

In 1987, Admotec started as a motion control distributor near Zurich, and early on, it keenly recognized the core pain points of traditional transformers in high-speed motor applications - the susceptibility of winding rotors to centrifugal force failure, accuracy degradation with speed, and insufficient resistance to harsh environments. In 1994, the company acquired ROTASYN solid rotor rotary transformer and pioneered the use of a non winding solid rotor design, which solved the hidden dangers of wear and loosening during high-speed rotation structurally and laid the core architecture for subsequent products.

Entering the 21st century, Admotec Precision has achieved a dual breakthrough in technology and market. In 2005, its Rotasyn series products were successfully matched with the Hi Lift system of the A380 aircraft, achieving synchronous maiden flight of six devices and verifying the reliability of the products under aerospace conditions. In 2009, the company passed the EN9100/AS9100 aerospace quality management system certification and met the ISO9001 standard, fully benchmarking the strict requirements of the manufacturing industry in terms of production processes.

At this stage, the production end focuses on the dual improvement of "high precision and strong tolerance": by optimizing the Rotasyn magnetic circuit design, the angle accuracy is better than ± 18 arc minutes, and the repeatability is controlled within ± 1 arc minute to ensure accurate signal feedback at high speeds; Expand the working temperature range to -196 ℃ to+220 ℃, capable of withstanding high pressure and severe vibration at 1600bar, and suitable for complex media environments such as hydraulic oil and cutting fluid. In 2014, the US base was restarted and renamed Admotec Precision LLC, forming a pattern of Swiss R&D and dual production bases in Europe and America. Its products cover high-speed motor scenarios in multiple fields, from industrial automation to nuclear energy and shipbuilding.

In recent years, with the evolution of high-speed motors towards "higher speed, better energy efficiency, and more intelligent control", the production process of Admotec Precision has shown three major characteristics of "customization, efficiency, and scenario based". In response to the needs of different industries, the company has launched a differentiated product matrix: the RO2010 model achieves ultra-high speed adaptation of 160000 RPM, some models of the RO3620 series reach 150000 RPM, and the FM750 model covers mainstream industrial scenarios with 58000 RPM, fully meeting the needs from ultra high speed special motors to conventional high-speed equipment.

　　Admotec Precision's rotary transformer is designed specifically for high-speed motors, and its speed capability far exceeds that of traditional sensorsFor example:

RO2010 model: High speed can reach 160000 RPM, far exceeding the conventional requirements of high-speed motors.

FM750 model: Supports speeds up to 58000rpm, covering most high-speed motor scenarios.

Some models of RO3620 have a speed capacity of up to 150000 rpm, meeting the requirements of ultra high speed motors.

The production end deeply integrates third-generation semiconductor and intelligent manufacturing technology, adopts modular design to shorten the customization cycle, optimizes installation compatibility through frameless structure, allows the stator to be directly pressed onto the motor housing, and the rotor is fitted with a spindle to save axial space. At the same time, in response to the trend of greening, the product integrates environmental protection concepts into material selection and process design, reduces energy loss through low inertia design, and optimizes energy efficiency with intelligent control systems, which is in line with the development direction of "high efficiency and green" in the high-speed motor industry. Nowadays, its products have been widely used in fields such as F1 racing, new energy vehicles, and industrial robots, becoming the core support for precise control of high-speed motors.
