Renesa‘s inductive motor position sensing technology, which combines high precision, high stability, and high cost-effectiveness, is a significant leap in the field of motor position sensors and encoders

    Global semiconductor solution provider Reza Electronics (TSE: 6723) today announced the launch of a new Inductive Position Sensor (IPS) technology for high-precision motor position sensor ICs for robotics, industrial, and medical applications. This position sensing technology utilizes non-contact coil sensors, which can replace expensive magnetic and optical encoders commonly used in motor control systems that require absolute position sensing, high speed, high accuracy, and high reliability.

    Renesa‘s proprietary IPS technology uses sensing elements composed of copper coils etched on printed circuit boards (PCBs) to detect the position of metal targets. Unlike heavy-duty sensors based on magnets, IPS products can operate at a speed of 600 Krpm (electrical) and can detect position immediately upon startup, with a propagation delay of less than 2 μ s. Therefore, it is very suitable for high-speed rotating motors. In addition, the sensor technology also supports automatic calibration and linearization functions, ensuring consistent performance throughout the entire lifespan of the motor.

    Based on the cursor principle, the dual coil sensor technology supports up to 19 bit resolution and up to 14 bit accuracy, which makes it superior to similar products available on the market. Robust and durable sensor technology can operate reliably in harsh environments such as high temperature, dust, humidity, vibration, and electromagnetic interference (EMI). Inductive sensors are not affected by stray magnetic fields and do not require maintenance; And compared to magnetic sensors, it is less prone to errors. These advantages make inductive position sensors a more attractive choice compared to heavier and more expensive traditional optical encoders or magnetic encoders.

    Jan Leuckfeld, Senior Director, HPC Analog (Sensor) Division at Renesas stated, "Renesa‘s inductive position sensor technology is a significant leap in the field of motor position sensors and encoders. They will enable Renesa to provide robust, durable, high-precision, and cost-effective differentiated motor position sensor ICs for industrial applications

    Ulrich Marl, Key Account Manager at Lenovo+Bauer, a Reza customer and manufacturer of industrial system encoders, stated, "Position sensors used in factory workshops must be able to withstand extreme conditions such as humidity, high temperature, and vibration. Through collaboration with Reza, we have integrated IPS based technology into our encoder product portfolio to ensure reliability and safety, while reducing downtime in critical applications

    Inductive position sensor technology will support commonly used UART, ABI, and I ² C communication interface ensures seamless integration into industrial networks for real-time monitoring and data analysis. In addition, the new sensor technology will be supported by a complete toolchain, including specialized software for user customization and accuracy optimization. Renesa plans to combine the new sensors with the numerous compatible devices in its product portfolio to create a wide range of "successful product portfolios" that seamlessly collaborate, bring optimized low-risk designs to users, and accelerate product launch speed.
