The ground-breaking Inductive Position Sensor (IPS) technology, unveiled by Renesas Electronics Corporation, a leading supplier of cutting-edge semiconductor solutions, is set to transform motor position sensor integrated circuits for a variety of applications, including robotics, industrial automation, and medical equipment. This patented technology, which uses non-contact coil sensors, presents a compelling alternative to the costly magnetic and optical encoders that motor control systems frequently use, especially those that require absolute position sensing, high speed, precision, and dependability.
The IPS Technology Advantage
Cost-Effective Alternative to Magnetic and Optical Encoders: Renesas’ IPS technology uses copper coils engraved on a printed circuit board (PCB) to identify the location of a metallic target. This alternative to expensive encoders is more affordable.
High-Speed Operation: With a propagation delay of less than 2μs, Inductive Position Sensor devices can detect position instantly upon startup and function at a staggering 600,000 rotations per minute (electrical), in contrast to bulkier magnet-based sensors. The best-suited application for high-speed motors is this performance.
Auto-Calibration and Linearization: Renesas’ IPS tech ensures auto-calibration and linearization for consistent motor performance.
Unmatched Precision
Vernier Principle: The dual-coil sensor technology distinguishes itself from rivals in the market with its remarkable resolution of up to 19 bits and accuracy of up to 14 bits. It is based on the Vernier principle.
Robust in Harsh Environments: These sensors are made to withstand harsh environments, such as high heat, vibration, dust, moisture, and electromagnetic interference (EMI). They also resist the effects of outside magnetic fields.
Error resistance and Low Maintenance: Induction position sensors are a better option than magnetic sensors since they are less prone to errors and require less maintenance.
Endorsement and Collaboration
Industry Praise: Leading figures in the industry have praised Renesas’ induction position sensor technology. Renesas Senior Director Jan Leuckfeld said that it represents a major advancement in motor position sensors, providing durability, precision, and affordability.
Working together, Renesas and Lenord+Bauer: Lenord+Bauer is a well-known producer of encoders for industrial systems. They incorporated IPS technology to enhance safety, reliability, and reduce downtime in crucial applications.
