| Summary: | The main purpose of this work is to create conditions for the use of switched
reluctance motor in the traction electric drive system of rolling stock by increasing
the reliability of its bearings. The object of the study is the traction switched
reluctance motor. The task has been set, which consists in developing an algorithm
that allows to calculate the characteristics of the traction switched reluctance motor
at the stages of design and production, taking into account the forces of a oneway magnetic attraction. The forces of one-way magnetic attraction, arising in the
air gap of the electric motor with two types of its non-uniformity are studied. A
proposal has been made to limit the force of the one-way magnetic attraction to a
force at a permissible residual imbalance. As a result, an algorithm for determining
the characteristics of the traction switched reluctance motor is unique in its kind,
which makes it possible to reduce the effect of forces of the one-way magnetic
attraction on bearings. The use of switched reluctance motor with a long service
life of bearings in the traction drive system will make it possible to obtain a new
competitive rolling stock. |
