MotorAnalysis-IM

MotorAnalysis-IM is free software for design and analysis of induction motors and generators. MotorAnalysis-IM is based on automated finite element analysis (FEA) simulations and establishes a complete set of tools for design and analysis of induction machines. MotorAnalysis-IM is available as a MALTAB-based application or as a standalone program working without MATLAB.

Analysis methods

MotorAnalysis-IM provides results based on finite element analysis solutions and combines several analysis methods having different accuracy and computation speed. You can choose the appropriate analysis method depending on the phase of the design process and speed/accuracy tradeoff.

• Estimation of equivalent circuit parameters based on no-load and load test simulations
• Nonlinear behavior of magnetizing inductance is taken into account
• Calculation of most commonly used motor parameters like voltage, current, power, torque, power factor, efficiency and losses for different operating points as well as efficiency maps

• Based on nonlinear time-harmonic FEA assuming ideal sinusoidal current or voltage source supply
• Plots of voltage, current, power, torque, power factor, efficiency and losses for different operating points
• Air gap distribution and field plots

• Based on nonlinear time-stepping FEA
• Rotor rotation with air gap re-meshing
• Rotor bar skewing is taken into account with multi-slice simulations (solving several 2D slices all at the same time)
• FEA simulations with coupled electrical circuits
• Arbitrary supply current or voltage waveforms including PWM inverter supply
• Time-series data plots, air gap distribution and field plots with animation option
