Analog Output Module for Rotor Position Sensor Simulation and Electrical Fault Simulation
The Position Sensor Simulation FS (RPS) enables realistic generation of synchronous sine and cosine signals (GMR/AMR angle sensors), as used by position sensors in electric machines. Additionally, the system allows targeted simulation of electrical fault conditions. The RPS platform is based on the NI sbRIO-9608 and, thanks to its modular architecture and versatile communication interfaces (Ethernet & CAN-FD), offers a highly integrable solution for complex test environments.
Technical Description
The RPS simulation unit features a modular design, allowing scalable channel counts by combining multiple groups. The Position Sensor Simulation FS can be used to generate synchronous sine and cosine signals, similar to those provided by position sensors in electric motors.
Several expansion levels of the simulation are available. One module offers up to 30 analog outputs, enabling configuration of multiple output combinations. A key feature is the simulation of various fault conditions, such as phase shifts, amplitude and offset errors. Additionally, electrical faults like short circuits and open lines can be simulated. Factory calibration and high reliability ensure highly accurate long-term measurement results. Recalibration can be easily and conveniently performed at the IRS calibration lab.
Modular Channel Groups:
Each group provides 5 analog outputs.
Available in variants with 10, 20, or 30 channels.
Dual Mode:
Synchronization of two channel groups possible.
Communication & Control:
Ethernet: Full configuration and control.
CAN-FD: Full control; configuration via Ethernet required.
Isolation:
Each channel group is electrically isolated from other groups, the system power supply, and the housing.
Mechanics & Housing Options
The Position Sensor Simulation FS (RPS) is flexibly deployable – suitable for both laboratory and production testing environments.
19" Integration:
The modular hardware is prepared for integration into 6U 19" racks, allowing seamless incorporation into existing test benches.
Desktop Enclosure:
For development environments, manual test stations, or research facilities, the RPS is also available in a robust desktop enclosure. This variant can optionally be operated with 230VAC.
