Renesas Electronics Expands Inductive Position Sensing Portfolio to Automotive Motor Commutation Applications with IPS2550 Sensor

     Renesas Electronics Group announced the launch of the IPS2550 magnetless inductive position sensor. The IPS2550 features improved performance, easy customization, complete immunity to stray magnetic field interference, and reduced weight and size. Ideal. With its optimized bill of materials, the new sensor enables customers to cost-effectively tailor sensor designs for their applications and maximize sensor accuracy.

     Customers can also combine the new sensor with Renesas microcontrollers (MCUs), gate drivers and motor drivers to build complete motor commutation solutions for traction motors, electric power steering, starter generators and other motors application.

     Christian Wolf, Vice President of the Automotive Sensors Business Unit at Renesas Electronics, said: "We are very pleased with the favorable market response of Renesas' new inductive position sensing technology for industrial motors launched last June and look forward to the The new product IPS2550 brings the advantages of this technology to customers in the automotive sector. As a thinner, lighter non-contact sensor, the IPS2550 continues to provide the high performance and stability required for automotive applications, with flexibility and ease of customization and other features, allowing manufacturers to cost-effectively manufacture their own resolver or magnetic sensor replacements.”

     Based on Renesas' inductive position sensing technology, the magnetless IPS2550 supports a maximum speed of 600krpm (electrical cycle) and is designed around the motor, while accommodating off-axis (through-shaft and shaft-side) and shaft-end arrangements. Compared to alternative sensing technologies, customers can match the number of sectors to the number of motor pole pairs and improve accuracy in a cost-effective manner. The sensor's low profile and complete stray magnetic field immunity make motor integration easier and provide customers with the standard materials they need to manufacture their own resolver alternative, reducing BOM costs. Developed based on the ISO26262 standard, the IPS2550 can support the most challenging functional safety-critical applications as a single IC, meeting the system-level requirements of ASIL-C(D).
