CONSTRUCTIVE RELATIONS IN ELECTRIC MACHINES OF MECHATRONIC SYSTEMS WITH CONCENTRATED STATOR WINDINGS AND A TOOTHE NON-WINDING ROTOR

The issues of substantiation and selection of basic design relationships of induction machines with single-tooth windings, which can be part of newly developed mechatronic systems, are considered. The relationships substantiated in this work can be applied in the development of new mechatronic systems, especially when the task of developing mechatronic modules for specified dimensions is often encountered in practice, which requires the development of both motors, new angle and speed sensors. In addition, this task becomes more urgent when setting harsh operating conditions, such as low and high temperatures, shocks, vibrations, and operation in submersible servos filled with oil. All this makes it difficult or impossible to use a number of other non-electromechanical sensors, such as optical, discrete Hall sensors, which further narrows the range of purchased products for embedding in the specified dimensions of the module. The considered ratios allows to implement sensors not only for different product dimensions, but also to take into account the purpose, accuracy requirements, and design meters with different electrical reduction, with different number of phases. An additional advantage of developing sensors according to these ratios is manufacturability, simplicity and speed of development and the ability to quickly launch into production. In addition, the derived ratios make it possible to design an angle sensors, speed sensors, as well as electric motors and generators, which may be in demand in a number of special cases, for example, if it is necessary to minimize the moment of inertia of the motor rotor and to build high-speed machines.
