The operation process of the traction asynchronous electric drive rolling stock may be accompanied by occurrence emergency modes, which are characterized current overloads and lead to damaging power circuits or mechanical part drive. Therefore, studying electromagnetic processes that occur in modes is relevant, particular, for developing systems aimed at diagnosing protecting equipment. Ukraini...

Heavy machinery is critical to agriculture, construction, mining, and other sectors of a country’s economy. However, such vehicles consume high amount fuel, increasing production costs the emission polluting gases into atmosphere. One alternatives reduce fuel consumption electrification these vehicles, but definition an optimal topology for heavy still under study, works with electric drive sys...

Electrical Drive An electric drive is a system that converts electrical energy into mechanical energy. It also provides electrical control of the whole process through several devices and technologies (Figure 1). The objective is to create a smooth and versatile control to achieve a specifi c speed-torque characteristic. It is a key component of the power conversion chain between power sources ...

The paper considers problem of a servo drive speed limitation within the permissible values rate in condition of different impacts types. A fuzzy logic controller with speed limitation suggested for such electric drive. Control system with tis controller was tested on the laboratory stand of telescope rotary support axis.
