The “IRS cRIO Resolver Simulator” enables realistic simulation of resolver sensors and RVDT sensors (Rotary Variable Differential Transformer) in National Instruments Compact-RIO systems. It was specifically developed for testing applications in power electronics for electric machines (e.g., in electric and hybrid vehicles, in aviation, and many other applications) and provides an accurate representation of sensor signals for functional, end-of-line, or lifetime tests.
Technical Description
Resolver Simulation
Resolver sensors are commonly used in electric drives of hybrid and electric vehicles to accurately measure the rotor position and its speed. The cRIO module emulates the function of a real resolver sensor by generating an amplitude-modulated signal that is dependent on the current rotor position.
RVDT Simulation
The RVDT sensor is used for precise measurement of angular displacements and is often employed in aerospace due to its robustness. The cRIO module realistically simulates the operating principle of an RVDT, where a rotating metal core induces a differential voltage in the secondary windings.
