In the rotablator angioplasty system, the turbine causes the rotation of the catheter burr, which aids in removing plaque deposits from coronary arteries. The operational and control circuit of this system can be modeled as a dual-node RLC circuit with a current-controlled current source. When the input source voltage, inductance, and capacitance values are known, the shaft's driving voltage can be calculated using nodal analysis. By utilizing the angular frequency, inductance, and capacitance values, the impedance across the inductor and capacitor is computed, and a corresponding frequency domain circuit is drawn. Applying Kirchhoff's current law and Ohm's law at the first node, and substituting the expression for the source current gives a simplified equation. Similarly, applying Kirchhoff's current law and Ohm's law at the second node results in another equation. Substituting the first nodal equation and simplifying the equation further, gives the voltage at node one which is equal to the source voltage. Finally, the shaft voltage is transformed into the time domain.
