Motors and Generators


Disk Induction Machine
View the capabilities of the 3D Transient with Motion solver in a unique and truly 3D machine--an axial flux disk induction machine. The flux flows parallel to the axis of the rotor. Currents are induced in a flat disc-shaped aluminum rotor element. The 3D Transient with Motion solver was used to model both a run-up to synchronous speed and also to create a torque-speed curve.

Core Loss and Efficiency Calculations with Infolytica software
Magnetic losses (also known as iron losses or core losses) are an area of growing interest in fields such as advanced electric machines and transformers. See how Infolytica's software can give you more accurate results for both thermal and magnetic simulations.

Ensuring Electric Machine Efficiency with MagNet and OptiNet
The task of the machine designer--a tireless effort to optimize torque ripple, running torque, efficiency, cost and a whole host of other factors--is now made easier with the latest releases of MagNet and OptiNet from Infolytica.

Advanced Optimization of an IPM (Interior Permanent Magnet) Machine
This example looks at the optimization of a 3-phase, 4-pole single-barrier IPM (interior permanent magnet) using the combined power of MagNet (as the core solution engine) and OptiNet (as the optimizer).

The combined power of MagNet and The MathWorks' Simulink® is demonstrated here using the vector control of an Interior Permanent Magnet (IPM) motor.

IPM Motor with PWM drive and vector control
The vector control of an Interior Permanent Magnet (IPM) motor is simulated here using the combined power of PSIM, a circuit and systems simulator from PowerSim, and MagNet. PSIM simulates a rotor speed feedback loop, which generates PWM phase voltages. A transient motion solve running concurrently in MagNet uses these to calculate the coil currents, which are fed back to PSIM.
