Abstract
Objective: To develop a system of computer aided design for electrical traction drive complex, as a component of CAD for electric rolling stock. Modern approach for electrical traction drive complex design means the development of assembly of interconnected systems, such as electrical traction motor, transducer, control system, etc. The most striking instance of such an assembly is gated traction motor, that is somehow in-between electric machines and electric drives. It is usefull to start the developing of CAD gated traction motor by developing the CAD system for electromechanical transducer of gated traction motor. Methods: In the base of CAD system under development there is a technology of design of electromechanical transducer of gated traction motor. At the stage of electromechanical transducer magnetic circuit calculation the software for simulation of magnetic fields by finite elements method was used. Results: The paper suggests the structure diagram of CAD system for electromechanical transducer of gated traction motor. Calculating software language is Octave. The paper provides the results of magnetic field calculations for electromechanical transducer of gated traction motor FEMM software for finite-element simulation. Based on the results of magnetic field calculations the curve of electromechanical transducer energizing is plot. Also the practicability of FEMM software implementation at the design stage of magnetic circuit is confirmed. Practical importance: Obtained results are useful for creation of educational and research system for CAD for electric traction drive complex. Development of CAD system for gated traction motor will allow to master methods and approaches of design for electric machines and semiconductor complexes of electric traction drives in general.
