MotorSolve - IM
Induction Machine Design Software

MotorSolve IM is the only motor design software you need to get an accurate and complete prediction of your machine's performance. Our powerful automated finite element analysis engine is embedded inside, therefore no model exporting or additional software is required.

Use MotorSolve IM to design your machine and take into account important effects such as:

  • Leakage Inductances
  • Iron Losses
  • Efficiency
  • Deep Bar Effects
  • Stator End Effects
  • Effects of switching on motor characteristics due to inverter fed phases

Motor Analysis

MotorSolve IM calculates machine performance based on automated finite element analysis simulations. There is no need to construct the model, perform mesh refinements and extensive post-processing to extract motor related results. MotorSolve performs these operations for the user.

Using the template interface, a desired waveform, quantity or field is selected with the operating conditions specified.

MotorSolve IM includes several analysis methods, suitable for different phases of the design process. The waveforms, fields and charts are computed using one of the selected analysis method, allowing users to choose the computation time based on their required degree of accuracy.


Equivalent circuit analysis
  • Simulation of no-load, locked-rotor and impedance tests to determine the circuit values (based on IEEE standards)
  • Core losses are taken into account
  • Improved leakage inductances approach that separates rotor and stator leakage fields at the correct ratio, or the ratio can be specified manually

AC Field Analysis
  • Automated nonlinear finite element simulation
  • Ideal voltage source at a single frequency
  • Lumped parameter variations at different slip values are taken into account
  • Losses and eddy current are taken into account

PWM (Inverter Fed) Analysis
  • Simulation of both the machine and inverter based on 3-phase bridge circuit
  • Automated finite element solution
  • Voltage driven or current driven
  • Harmonic content at source frequency, slip frequency, source-slip or rotational frequency

Motion Analysis
  • Automated nonlinear finite element simulation of the induction machine with the effects of motion
  • Induced eddy current, losses and slot/tooth effects taken into account
  • Saturation of magnetic materials at every step of the rotation
  • Harmonic content at source frequency, slip frequency, source-slip or rotational frequency
