Vector Fields Rotating Electrical Machinery Software
Vector Fields, a Cobham company, has launched new capabilities for its design software for rotating electrical machinery. The software — which combines the extreme accuracy of finite-element analysis (FEA) modelling with a design entry system that allows users to create models of electric motors or generators in minutes — allows users to achieve radical new levels of design productivity and efficiency. The software has proved very popular since it was introduced a year ago, and Vector Fields is adding numerous new modelling elements requested by users to speed design.
The software is an application-specific version of the well known Opera package, and provides a front-end to the electromagnetic simulator that speeds design entry by means of 'fill in the blanks' dialog boxes. Users select the form of motor or generator they want to design from a list of all common types, including induction, brushless permanent magnet and switched reluctance motors, and synchronous motors or generators. Then, by simply entering a list of perhaps 10 parameters to define mechanical geometry, material properties and electrical data, the model is automatically created. For example, the parameters might include diameters of rotor, stator, and shaft, stator tooth width and the number of stator slots.
