Moving Speed vs Moving Torque

Torque

Maxium Moving Torque is 276 Nm and Average Moving Torque is 244 Nm.

Efficiency

In Second Part of the Project material type of the magnet and Stator/Rotor is changed and Simulated again to observe Diffrent factors like Torque Production, B Mag, Flux Lines, inductance Etc. in diffrent Combinations of magnet and Rotor/Stator Materials.

Combination No.1

In this IPM Motor Simulation Magnet Material Used is ferrite magnet Y15H and material used for stator and rotor is Electrical Silicon Steel M19_29G.

it observed that after using Ferrite Magnets Y15H the Max. and Avg. torque is Reduced to 131 Nm and 113 Nm respectively

Speed Torque Plot

B_Mag of IPM Motor with Y15H Ferraite Magnets and M19_29G

B_Mag of IPM Motor with N36Z_20 Neodymium Magnrts and M19_29G

Magnetic Flux Density Produced by the ferrite Magnet y15H is Less than the Neodymium N36Z_20 used in Prius Motor.

Combination No.2

Here in place of Electrical Silicon Steel M19_29Z Stainless Steel is used for Rotor and Stator and the magnet material is N36Z_20

Average Moving Torque produced by IPM motor With Stainless Steel Stator and Rotor is 19 Nm which is very low in compare to Stator/Rotor Made up of Electrical Silicon Steel which is tailored to produce specific magnetic properties like low Core losses, Small Hysteresis and High Permeability.

Speed Torque Plot

Magnetic Flux Density Produced by Neodymium Magnet N36Z_20 is not able to influence the organization of Magnetic Dipoles in Stainless Steel because of very low Permeability.
