Automated FEA Results

MotorSolve is based on the same robust technology as MagNet, incorporating nearly 30 years of experience and knowledge. The key difference in MotorSolve is the entire model generation and simulation process which has been streamlined and automated for electric motors, making it possible to get accurate results based on finite element analyses with just the click of a button. No drawing, no manual mesh refining and no post-processing necessary.

Resolution and accuracy controls can be set to different levels depending on the current stage in the design cycle.

Most modern electric motors do not adhere to the rules of thumb and general approximations used by designers for decades. There is a growing demand for software that delivers reliable results and does not give false predictions for crucial performance factors resulting in avoidable and costly complications. Only FEA simulations:

• Offer a high degree of accuracy
• Predict performance properly when there is saturation

and only MotorSolve offers these results and more in a convenient automated design environment tailored to modern electric motor designers.

Analysis Types

MotorSolve has several types of analysis capabilities which are entirely integrated into the software architecture and can be used interchangeably without any pre or post processing steps. It's as simple as specifying the operating conditions and selecting the desired result.

D-Q analysis is ideal for initial phases of design when sizing or other parameter variations are common - the methodology is based on a single FEA simulation to characterize the performance of the electric motor. The component values from the equivalent circuit of the D-Q approximation can also be obtained using the Lumped Parameter analysis.

Transient analysis offers the highest degree of accuracy by performing a full time-stepping non-linear FEA simulation of the motor operating with an either wye or delta connected sinusoidal or six-step drive.

Cogging torque analysis quickly and easily provides accurate cogging torque for motors with or without skew.

Finally PWM analysis performs a dynamic simulation of the electronic commutation in a three-phase full-bridge squarewave or sinewave drive with current regulation. This is especially important at high speeds when the current waveforms may differ significantly from the ideal due to limited rail voltage.
