“Inductive position sensing is changing the game for industrial motor commutation as demands for high accuracy, high efficiency, and cost efficiency increase, particularly for multi-pole pair motors and off-axis applications,” says Renesas vp, Christian Wolf, “with the IPS2200, we are excited to offer a solution that takes customers from concept to PCB layout, enabling them to design their own resolver replacement and achieve lighter, better performing motors for their industrial, robotic, consumer and medical applications. Moving forward, Renesas will also explore the inductive sensors for use in automotive applications.”
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.
