IPS2200 delivers total stray-field immunity, lower weight, and cost-effective design in a thin profile for industrial motors...

Renesas Electronics Corporation introduced the magnet-free IPS2200 inductive position sensor. Featuring high accuracy and speed, total stray field immunity, and efficient motor integration in a thin and lightweight form factor, the IPS2200 is ideal for use as an absolute position sensor in a wide range of industrial, medical, and robot applications. The sensor allows customers to cost effectively tailor sensor design for their applications and maximize the performance of the sensor’s accuracy.

The IPS2200 is designed around the motor, allowing customers to match the number of sectors to pole pairs of the motor to maximize accuracy, accommodating both off-axis (through shaft and side shaft) and on-axis positioning. The magnet-free IPS2200 is up to 10x thinner and up to 100x lighter with up to 250 krpm electrical speeds compared with traditional resolvers.

The sensor’s thin and light form factor and total stray field immunity enables easier motor integration and provides the standard materials required for customers to manufacture their own resolver replacement – reducing bill of materials costs. With its four- or six-wire operation, the IPS2200 provides up to 10x faster speeds and very low latency compared with resolver- or magnetic-based solutions.
