With a comprehensive reference solution, users can start their position sensing system development at low cost
Beijing, China – Renesas Electronics (TSE: 6723), a global semiconductor solutions provider, today announced the launch of a new Resolver 4.0 reference design catalog for innovative inductive position sensors for automotive and industrial motors. With this catalog, engineers now have access to 80 instant design resources based on IPS2 motor commutation sensors, each reference design for a unique motor shaft or pole pair configuration. These reference solutions come with complete design documents, test reports, tools, and guidelines to help engineers shorten design learning time and speed the design-to-production process.
The Resolver 4.0 catalog offers turnkey solutions that can be implemented in a wide range of applications such as automotive systems, robotics, servo motors, home automation, and medical. The reference design includes complete schematics, PCB designs, and Gerber files, enabling engineers to start building a working sensing solution right away. Renesas also accompanies these reference designs with a software stack, complete tool support, test reports, bills of materials and other documentation. In particular, Renesas’ Inductor Optimization Tool (ICOT) enables the design of optimized sensing elements based on experiments and performance simulations of air gap changes, including precision and error analysis in the Resolver 4.0 catalog. In addition, users can visit the Renesas website to watch IPS webinars and learn about ideal design practices.

Jan Leuckfeld, Senior Director of product Marketing, Automotive Simulation/Sensors Division, Renesas Electronics, said: “One of the biggest challenges for designers using inductive position sensors is the variety of variables such as size, design of sensing elements, axis arrangement and number of pole pairs. Our PCB designs in the Resolver 4.0 catalog provide the key elements for each solution and are fully optimized and tested to meet the different needs of these motor control systems. Developers can now choose from more than 80 turnkey designs in the catalog to customize a work plan for their application.”

IPS2200 and IPS2550 sensors

Thanks to Renesas’ proprietary inductive position sensor technology, these IPS sensors weigh significantly less than traditional magnetic-based solutions and support high speeds – up to 600 krpm for the IPS2550 and 250 krpm for the IPS2200 (both electrical) – to support high-speed motor reversing in passenger cars or motor control in industrial equipment. In addition, IPS sensors are completely unaffected by stray fields, are less sensitive to noise and vibration, have excellent efficiency and accuracy, and are more reliable than magnet solutions.
