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.

Creating a Response Surface Model of an Actuator for Multi-Discipline Design in SystemVision

A response surface model of an actuator is created by performing several magnetostatic analyses at different currents and positions in MagNet. The RSM can then be used in system simulators, such as SystemVision from Mentor Graphics.

Creating a VHDL-AMS model of a claw-pole alternator

A VHDL-AMS model of a claw-pole alternator is created using the System Model Generator. The SMG creates a Response Surface Model (RSM) of the claw-pole by driving MagNet to execute a number of static solves at different phase currents and rotor positions. This RSM is embedded in the VHDL-AMS file to create a component which is functionally equivalent to the original MagNet model, but which can be evaluated extremely quickly in a transient circuit simulation.

Current distribution in a Claw-pole Alternator

The device is a claw-pole automobile alternator with a three-phase output winding on the stator. A field coil around the rotor core is used to induce flux in the output windings as the rotor spins.

Demagnetization of Permanent Magnet Motors

MagNet's demagnetization analysis features allow the user to study the demagnetization characteristics of machines containing permanent magnets. It includes three probes of this phenomenon: the Demagnetization field, Demagnetization prediction field and Demagnetization proximity field. This example demonstrates how demagnetization properties are set in MagNet, and then apply this to a BLDC motor.

Demonstrating a variation of the MagLev suspension system

The performance of this machine is simulated using MagNet’s Transient 3d with Motion solver. The vehicle, consisting of the aluminum channel with payload, is given six degrees of freedom so that it is free to rotate about the roll, pitch and yaw axes and so that it is also free to move in all three dimensions (up-down, left-right, forward-backward). The vehicle is initially resting on supports 1 cm above the track, which is 0.5 cm below its equilibrium position when the track is energized.

Design and Analysis of a 2 HP Wound Field Induction Motor

A 4 HP wound field induction motor example is used to demonstrate some of the design and analysis capabilities of MotorSolve IM. The motor contains 30 rotor slots and 36 stator slots. This example showcases the features of MotorSolve IM that allows the user to implement a typical design cycle. This includes automated winding selections, load point analysis, bridge simulations etc.
