Inductive position sensor allows tailor-made designs, says Renesas
Industrial motor commutation enters a new era with high accuracy inductive position sensing, using the magnet-free IPS2200 inductive position sensor, claims Renesas Electronics.
It can be used as an absolute position sensor in industrial, medical and robot applications, maximising its high accuracy and speed, total stray field immunity and efficient motor integration in a thin and lightweight form factor. Customers can cost-effectively tailor sensor design for their applications and maximize the performance of the sensor’s accuracy, according to Renesas.
Christian Wolf, vice president, automotive sensor business division at Renesas, said that the IPS2200 can “take 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”. He also said that Renesas will explore its 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 maximise accuracy. It can also accommodating both off-axis (through shaft and side shaft) and on-axis positioning. The magnet-free IPS2200 is up to 10 times thinner and up to 100 times lighter with up to 250krpm electrical speeds compared with traditional resolvers.
The four- or six-wire operation IPS2200 is also claimed to provide up to 10 times faster speeds and very low latency compared with resolver- or magnetic-based solutions.
The IPS2200 is industrial qualified, with stable operation in harsh environments and ambient temperatures of -40 to +125 degrees C.
Renesas also offers off-the-shelf tools that can be used to create tailored and customised sensing elements, as well as custom tools that can achieve coil optimization sets within about 30 minutes.
The IPS2200 and the IPS2200STKIT evaluation kit are available now.
