Simcenter E-machine Design - BLDC
Brushless DC and Permanent Magnet AC Motor Design Software

Simcenter E-machine Design BLDC is the only motor and generator 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.
Overview

Performance cannot be predicted by general approximations and magnetic circuit calculations alone. Simcenter E-machine Design BLDC performs accurate FEA-based machine simulations to:

  • Predict performance properly when there is saturation
  • Account for all loss sources, such as eddy current and hysteresis

        Motor Analysis

        MotorSolve BLDC 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 BLDC 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.

        ANALYSIS TYPES

        D-Q & Lumped Parameter Analysis
        • Ideal for what-if analysis: initial sizing or design variations
        • Rapid: based on a single FEA simulation to characterize the performance
        • The component values from the equivalent circuit of the D-Q approximation can also be obtained using the lumped parameter analysis

        PWM Analysis
        • Perform a dynamic simulation of the electronic commutation in a three-phase full-bridge
        • Squarewave or Sinewave
        • Important at high speeds: current waveforms differ significantly from the ideal
        • Also supports non-linear PWM analysis method

        Motion Analysis
        • Perform a full time-stepping non-linear FEA simulation
        • Wye or Delta
        • Sinusoidal or six-step drive
        • Highly accurate for all types of operating conditions and ideal for final design verification
        Generator Analysis

        MotorSolve BLDC also offers an optional generator analysis feature. The result waveforms and charts, applicable to both motors in generating mode and AC generators, can be computed with one of four different analysis types available.

        ANALYSIS TYPES

        Operating Points
        Generated a chart of the selected quantities related to the short-circuited and maximum power point of the generator. The results are calculated from the nonlinear D-Q model of the motor, obtained from a FEA solve of the currents between 0 and the short-circuit current.

        DQ Analysis
        • Ideal for what-if analysis: initial sizing or design variations

        • Also supports non-linear PWM analysis method

        Motion Analysis
        • Perform a full time-stepping non-linear FEA simulation to simulate a generator connected to resistive/inductive load
        • Wye or Delta
