Motor Performance Evaluation

You need to evaluate what sort of motor to use and what sort of design parameters it requires. Do you need the accuracy of an FEA tool or will our built-in models work?

PSIM provides a direct link with the JMAG family of FEA tools. Co-simulate directly with JMAG or import a motor model from the free online JMAG-express tool.

If the detail of an FEA model is not required, PSIM and DSIM both provide a full library of motor models for you to use. Various types of linear and non-linear motor models covering the full spectrum of motors, everything of induction and PMSM through to switched reluctance and DC. Consult the full list of supported machine models here.

Make use of our power scripting tools to automate your simulations and analysis to help you work smarter not harder.

Motor Control Design

Designing controllers of a motor drive can be tricky due to the multi-loop structure and the nonlinearity. With the Motor Control Design Suite PSIM will close the current and speed loops and give you a working motor drive simulation for you to work from. Our design suite implements Max Torque Per Amp Control & Field weakening, with proper operating limits for power & torque.

If you want to close the loops yourself or implement your own novel algorithms, PSIM and DSIM both contain all the needed control library elements. You can even embed c code into the simulation to see how it performs.

If you still use Simulink for control design you can also co-simulate a motor drive in PSIM with the control components in Simulink.

Sensorless Control

To help design sensorless control of a motor drive system, PSIM provides convenient tools for users to implement TI’s sensorless control algorithm InstaSPIN quickly. You can simulate the function of the algorithm and also perform embedded code generation for quick and easy hardware implementation.

If you don’t want to use InstaSPIN, all of the necessary library elements are provided, sliding mode observer (SMO), c code in simulation, etc. To allow you to quickly design and simulate your own sensorless algorithm.

Power Hardware Design

The power stage of a motor drive has several key design decisions that will greatly impact system efficiency, heatsinking, electromagnetic interference (EMI), and the motor drive performance envelope.

Inverter loss calculation and comparison of different devices can be carried out easily. One can calculate the conduction and switching losses, and junction temperatures under different operating conditions and use a thermal equivalent circuit to model heatsinking requirements. This allows you to make critical design decisions like switching from IGBTs to SiC MOSFETS.

Easily compare the various inverter gating methods –  such as SVPWM, DPWM, 6-pulse, etc. – for thermal/efficiency performance with motor drive performance.

Electromagnetic interference, EMI, is an extremely important design consideration as motor drives become more connected with other sensitive electronics. Easily evaluate and design filters with our EMI Design Suite.

Quickly and easily understand your DC link specifications like sizing and your DC bus capacitor and its ripple current rating.

Of course, all of these studies and comparisons can be automated with our powerful scripting tools.
