Ansys Maxwell is an EM field solver for electric machines, transformers, wireless charging, permanent magnet latches, actuators and other electric mechanical devices. It solves static, frequency-domain and time-varying magnetic and electric fields. Maxwell also offers specialized design interfaces for electric machines and power converters.
With Maxwell, you can precisely characterize the nonlinear, transient motion of electromechanical components and their effects on the drive circuit and control system design. By leveraging Maxwell’s advanced electromagnetic field solvers and seamlessly linking them to the integrated circuit and systems simulation technology, you can understand the performance of electromechanical systems long before building a prototype in hardware.
Maxwell offers trusted simulation of low-frequency electromagnetic fields in industrial components. It includes 3-D/2-D magnetic transient, AC electromagnetic, magnetostatic, electrostatic, DC conduction and electric transient solvers to accurately solve for field parameters including force, torque, capacitance, inductance, resistance and impedance.
Slice-only technology enables a cyclic repeatability simulation technique for electric motor applications. The analysis has been improved by efficiently solving just a slice of the motor, employing non-planar boundary conditions, using symmetric mesh and replicating results to the full model. To learn more about how “slice-only” technology helps simulate complex electric motors, read the blog: How to Model and Simulate Complex Electric Motors.
