Renesas Electronics Corporation, a provider of advanced semiconductor solutions, has released a catalog of reference designs for its innovative inductive position sensors aimed at automotive and industrial electric motors. With the Resolver 4.0 Catalog, engineers now have a resource of 80 instant designs based on IPS2 motor commutation sensors, with each reference design targeting a unique motor shaft or pole pair configuration.
These reference solutions come with complete design files, measurement reports, tools, and guidelines to help engineers reduce their design learning curve and accelerate hardware production time.
The Resolver 4.0 catalog offers market-ready solutions that can be implemented in a wide range of applications, such as automotive systems, robotics, servo motors, home and medical automation. Reference designs include complete schematics, fully wired PCB designs, and Gerber files, allowing engineers to immediately begin building working sensing solutions.
Renesas complements these reference designs with software stacks, full tool support, documentation such as measurement reports, bills of materials and more. In particular, the Renesas Inductive Coil Optimization Tool (ICOT) enables the design of optimized sensing elements based on experiments with air gap variations and performance simulations, including accuracy and error analysis available in the Resolver 4.0 Catalog. Additionally, users can visit the Renesas website to watch IPS webinars and learn about design best practices.
“One of the biggest challenges for designers using inductive position sensors is the wide range of variables such as dimensions, sensor element designs, axis arrangements and number of pole pairs,” said Jan Leuckfeld, senior director of Product Marketing from Renesas'. Automotive Analog/Sensors Business Division. “Our comprehensive PCB designs in the Resolver 4.0 Catalog offer key elements for each solution and are fully optimized and tested to meet the diverse needs of these motor control systems. Developers can now choose from over 80 ready-to-use designs available in the catalog to select a custom working solution for their application.”
The sensors
Based on Renesas' proprietary inductive position sensor technology, these IPS sensors weigh significantly less than conventional magnet-based sensors and offer fast rotational speeds — up to 600 krpm for the IPS2550 and 250 krpm for the IPS2200 (both electric) — to withstand high temperatures. engine speed switching for passenger cars or engine control for industrial equipment.
Furthermore, IPS sensors are completely immune to stray fields, are less sensitive to noise and vibrations, have superior efficiency and accuracy, and are less susceptible to errors than magnets.
