MotorSolve IM calculates machine performance based on automated finite element analysis: no drawing, no manual mesh refining and no post-processing necessary.

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

Characteristic curves comparing multiple designs and/or operating points makes what-if analysis easy.

Analysis Types

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
