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.

IPM Motor with PWM vector control in PSIM 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.

Levitation with arbitrary motion Here is an example of an aluminum plate that is 3 mm thick and positioned above two coils whose current is 180 degrees out of phase. The motion of the plate when the initial position is off center can be modeled using three degrees of freedom: translation along the x and y-axes and rotation about the z-axis.

MagLev Startup This gallery page demonstrates a variation of the MagLev suspension system that implements the "Magnetic River" concept; it is based on repulsion forces from dynamically induced eddy currents. The idea is to use the same set of coils for both levitation and propulsion. In the motor example shown on this page, the coil structure is in a transverse flux configuration similar to that used in the prototype NASA MagLev for a shuttle launch system.

Perforated Levitating Disk This page examines a disc that first jumps from its resting position, oscillates for a certain period until finally levitating at a specific height above a coil, which is using an AC current as its input source. Of the two animations that accompany this page, one shows the dynamic position of the levitating plate whilst the other demonstrates the current density of the plate through a few cycles.

Permanent Magnet Stepper Motor The damping due to bearing friction is taken into account in this simulation of a permanent magnet stepper motor. The motor is made of a stator with eccentric pole faces and a rotor made of samarium cobalt permanent magnet (magnetized in a fixed direction) that rotates in steps of 180 degrees. This page displays some quantities of interest to the user such as force/torque, position, velocity, and acceleration.

Variable Reluctance Sensor Variable reluctance sensors are used to measure position and speed of moving metal components. This sensor consists of a permanent magnet, a ferromagnetic pole piece, a pickup coil, and a rotating toothed wheel. As the wheel rotates, the reluctance of the flux path through the coil changes, which results in a change in voltage that is measured by an external circuit.
