![]() ![]() It also allows to design two-phase windings for single-phase motors, as well as converting three-phase to two-phase windings and viceversa. 8), 6 single-layer and 3 double-layer windings, as well as fully-editable single- and double-layer windings, where the user is able to define the sides position and number of turns of each coil in each phase. BobiSoft 2.0 (beta version under test) can handle windings for stator cores with up to 180 slots and offers 9 different automatically-generated winding types (Fig. The automatic reports are an excellent way to show to the clients of repair shops what was actually done in the service and to demonstrate the quality of the provided service. Each project/design can be saved as a separate file (*.bob example attached), which can be attached to s, facilitating the stator winding technical information/data exchange and organization/standardization, promoting an easierĢ and error-free data exchange between the professionals dealing with motor repair/rewinding tasks. Moreover, there is a section for the core loss test that performs all the required calculations. Design procedures that take hours can be done within a few minutes. A section for additional information on the rewinding/repair service is also offered, in which some quality control information and photos can be saved (Fig. Key electrical and magnetic data is computed and presented immediately for both the original and new windings (Fig. 4 and 5), which can then be printed out and used to help positioning correctly the coils in the stator. After concluding the new design, the user can print the graphical (circular and planar) or numerical schemes of the coils (Fig. 2 and 3) and, after that, it will be able to change the original winding and check for the improvements in the Joule losses and spatial harmonic distortion of the air-gap MMF. Basically, the user has to fill-up the original mechanical and electrical parameters of the motor (Fig. Computing algorithm to improve or change the original winding design. It helps the user to quickly, easily and accurately design an optimized motor winding, computing key stator winding parameters such as MMF space harmonics and total distortion, wire length, weight, resistance, conduction losses, magnetic flux, current density, etc. This software tool is very easy to use and integrates a unique computing algorithm that simplifies the original winding improvement or change process (Fig. Short Description In order to facilitate the (re)design process of the motor stator windings and to help repairers/rewinders improving the motor efficiency, a software tool was developed in 2004, named BobiSoft. ![]() 1 Software Tool for Fast and Optimized Stator Winding Design of Three-Phase Induction Motors 1. ![]()
