cRIO Resolver Simulation & RVDT Simulation
The “IRS cRIO Resolver Simulator” enables realistic simulation of resolver sensors and RVDT sensors (Rotary Variable Differential Transformer) in National Instruments CompactRIO systems. It was specifically developed for test applications in power electronics for electric machines (e.g. in electric and hybrid vehicles, in aviation and many other applications) and provides an accurate reproduction of sensor signals for functional, end-of-line or lifetime tests.
Technical description
Resolver simulation
Resolver sensors are widely used in the electric drives of hybrid and electric vehicles to measure rotor position and speed precisely. The cRIO module emulates the function of a real resolver sensor by generating an amplitude-modulated signal that depends on the current rotor position.
RVDT simulation
The RVDT sensor is used for precise measurement of angular displacement and, thanks to its robustness, is widely used in aerospace. The cRIO module faithfully simulates the operating principle of an RVDT, in which a rotating metal core induces a differential voltage in the secondary windings.
