Work Flow Diagrams Using Stencil - MS Visio

Creating a basic flow chart with MS Visio

Nine Advantages of Multiphase Machines over Three Phase machines.

·    1. The required current rating of the power electronic switching devices used in the inverters and converters is reduced as the number of phases increases for the same machine power rating,

·        2. The torque ripple is reduced in the multiphase machines,

·       3.  Stator copper losses are reduced leading to higher efficiency,

·       4.  Power per root mean square (rms) current ratio is increased,

·     5.    Smaller rotor current harmonics are produced leading to more stable and reliable operation,

·       6.  Multiphase machines have inherent fault tolerance,

·        7. Multiphase machines have higher power and torque density for the same machine size,

·        8.  There is less interaction with the dc link current when VSI are used,

·       9.  Less noise and vibrations.
