What does the finite element analysis of the motor analyze?

With the improvement of the level of electrification and product intelligence, motors, transformers and high and low voltage electrical appliances are more and more used in various equipment and life. Motors and electrical appliances are developing towards the direction of large capacity, small volume and intelligence. Today’s electrical and electrical design faces more complex technical challenges, which can only be met by fully utilizing modern engineering simulation techniques.
Typical application areas
1) Electromagnetic simulation. Electromagnetic simulation plays a very important role in the design of electrical machines. Electromagnetic simulation can predict the efficiency of electromagnetic conversion, the loss and heat of each component, electromagnetic force / torque and other parameters, which is the basis of further thermal simulation and structural simulation.
2) Electric field simulation. With the increase of electrical equipment capacity and working voltage, the necessity of electric field simulation is more urgent. Electric field simulation can predict the performance indicators of equipment such as insulation, discharge and breakdown probability.
3) Thermal simulation. Overheating will reduce the reliability of the motor, and even burn out. Therefore, thermal analysis and thermal design are very important in the design of electrical machinery. Thermal analysis can optimize the cooling scheme and improve the cooling effect.
4) Structural strength and fatigue simulation. The use of structural analysis software electrical machinery in mechanical load and thermal load under the action of strength, stiffness, vibration and fatigue life, can improve the reliability of equipment.
5) Noise analysis. Simulating structural vibration noise and electromagnetic noise.
Electromagnetic simulation
Steady-state magnetic field analysis: excitation does not change with time, such as the magnetic field of permanent magnet, the magnetic field generated by the steady current, etc.
Harmonic magnetic field analysis: excitation varies according to the law of sine and cosine, such as induction motors.
Transient Magnetic Field Analysis: Excitation Varies Irregularly with Time
