Latest Patents
Gurusamy holds a patent for a system designed to estimate the number of shorted turns in a permanent magnet synchronous motor with inter turn short circuit faults. The patent describes a method that estimates the fault severity index and the number of shorted turns in permanent magnet motors (PMSM) experiencing inter turn short circuit faults (ITSC). This method involves exciting the machine with DC current under standstill conditions to obtain the winding resistance seen by the d-axis of the machine. The estimated d-axis resistance provides valuable information regarding the fault severity index, which is crucial for diagnosing issues in faulty motors. This innovative approach eliminates the need for complex modeling with various machine prototypes or finite element analysis (FEA) models to understand the relationship between machine currents and short circuit currents. Additionally, the method addresses challenges related to inverter non-linearity effects, such as distortion voltage due to dead time effects and voltage drops across switching devices.
