AC Synchronous Reluctance Machine for Traction Application

In this example, a 55 KW traction motor is designed using a stator that was originally designed for a squirrel cage induction motor for a similar output rating and application. The design of the new machine uses the stator of the induction machine and only the rotor geometrical parameters and configurations are used as free design parameters to achieve the target performance criterion.

Advanced Optimization of an IPM Machine

This example looks at the optimization of a 3-phase, 4-pole single-barrier IPM using the combined power of MagNet and OptiNet. The goal is to optimize the motor’s performance with respect to a reasonably realistic and complex objective function by changing a few simple geometric parameters (the size and position of the permanent magnets) and the advance angle.

Battery Charging with Maximal Peak Power Tracking

A maximal peak power tracking (MPPT) example for wind power plant is implemented in this example. The load is a battery that is subjected to a variable speed realistic wind profile. The system simulated consist of the following components; a wind turbine, a planetary gear system, a generator, a load (battery) and a 3-phase bridge regulator for the generator.

Calculating the steady-state ohmic and core losses in a BLDC Motor with temperature effects

The goal of the analysis is to predict the steady-state temperature of the motor and verify if the rotor magnets will demagnetize. A 3d transient thermal analysis coupled to a 3d transient with motion magnetic analysis is used to calculate the steady-state temperature distribution after a few hours of operation; the simulation will determine the change in performance due to increased winding resistance and degraded magnetic properties.

Cogging torque in a skewed brushless DC motor

The predicted cogging torque in a brushless DC motor is compared between two different stator geometries: a straight stator and a skewed stator. MagNet makes it easy to set up multiple problems for solution at different rotor angles. And MagNet’s Static 3D solver reports the magnetic forces and torques experienced by each body in the model, so it is easy to create a torque-angle curve.

Core Loss and Efficiency Calculations

Infolytica's products have adopted an advanced core loss model. This can be used to accurately determine the efficiency of a permanent magnet machine, or when coupled with ThermNet, provide a better simulation of temperature changes in a permanent magnet voice coil.

Co-simulating the current vector control of an IPM motor

The current vector control of an IPM (interior permanent magnet) motor is simulated here using the combined power of the PSIM circuit and systems simulator from PowerSim and MagNet. This is a co-simulation in which both PSIM and MagNet run their transient solvers simultaneously, with a constant data exchange between the two to keep the shared quantities (voltages and currents) synchronized.
