Simulating a Cyclic Electron Path in a Magnetron

The trajectory of an electron in a magnetron can be simulated based on the fields present in the space between the cathode and the anode.Using MagNet, ElecNet and the Trajectory Evaluator, the electric and magnetic field strengths are adjusted so that the path of the electron does not reach the anode and forms a cyclic trajector.

Simulating a Halbach cylinder Servo Motor

MagNet's magnetization pattern predicting capability is used to design a Halbach cylinder BLDC servo motor in this example. A four pole 12 slot, 3 phase machine is designed here including accurate modeling of an external, impulse magnetization of the Halbach cylinder.

Simulating a Skewed Induction Machine in 2D

By definition, skewing is a three-dimensional feature and usually requires lengthy 3D simulations. Fortunately, MagNet has unique mesh capabilities which make it possible to accurately model skew using the powerful 2D solver and a multi-slice approach.

Simulating Multiple Moving Parts of a Magnetic Gear

This example shows simulations of a magnetic gear system and it’s performance. In this example, the magnetic planetary gear assembly is analogous to an equivalent mechanical system, with the inner rotor acting as the sun gear, the outer rotor as the ring gear, and the stationary steel pole pieces acting as planetary gears (it is the magnetic field that spins, not the pole pieces themselves). There are 2 pole pairs on the inner rotor and 5 pole pairs on the outer rotor, making the gear ratio of this assembly 2.5:1. The model is shown here.

Simulating Particle Filtration with an Electrostatic Precipitator

The path of particles entering an electrostatic precipitator and their collision with the collection plates are tracked, simulating an air filtration process. Voltage is applied to the collection plates in order to ionize the gaz around each electrode.

Simulating Pulse Width Modulation with a Brushless DC Motor

MotorSolve BLDC’s features include obtaining performance results using PWM drive circuits, some examples of which are presented here. The figure shown here is an example of a wye-connected 3 phase drive circuit used in such simulations. PWM capabilities of MotorSolve BLDC include delta connected circuits and sinusoidal and six-step drive types. Also, switching losses are taken into account in the simulations.

Single-phase induction motor (T.E.A.M. Problem 30B)

Presented is a half-model of a single-phase induction motor which has a periodic boundary condition on the plane of symmetry. It was simulated using the MagNet transient 2d with motion solver in a single transient run, as a velocity-driven problem..
