Software for three-phase induction motor stator winding design

BobiSoft® software has been specially developed for the design and comparative analysis of three-phase windings of low-voltage induction motors. It allows two different windings to be designed/evaluated simultaneously, for an easy and fast comparison. Automatic reports containing winding key parameters, numerical schemes, graphical schemes, MMF waveforms, core-loss test data, and client/service data, can be generated and printed.


Some facts you should know on motor rewinding:

• The three-phase induction motors are rewound 3-4 times over their lifetime;

• The motor repair is more competitive, but also more demanding, for high-efficiency motors;

• Frequently, systematic design errors in the winding redesign are identified;

• The time to optimize a motor winding is quite long;

• Typically, there is a lack of accuracy and organization of the technical information associated with the winding projects;

• It is difficult to send/receive winding projects electronically (e.g., e-mail);

• It is difficult to have access to motor design reference data (e.g., current density, magnetic induction, etc.);

• Typically, the stator core state is not evaluated during the rewinding process;

• In most cases, the motor users don´t receive a technical report (or repair form) from the rewinder.

What does the BobiSoft®?dispositivo

• Allows to modify a project in a systematic way and to compare the impact of the introduced changes with the original design;

• Allows to perform a winding design in less than 10 minutes;

• Allows sending technical information in editable electronic format (*.bob);

• Helps organizing the technical information associated with each motor repair/rewinding service (a database can be easily created);

• Helps performing quality control tests (e.g., Core Loss Test);

• Helps understanding the impact of different stator winding parameters in the motor performance;

• Generates automatic technical reports.
