Pavlik V. Effectiveness of electric drives of agricultural machines during using electric motors of special appointment

The Object - process of the transmission and transformations to energy from electric network to gross worker machines when using general industrial and special electric motors. The Purpose - increasing technician-working factors electro drive agricultural machines by use the electric motors of the special purpose. The Method - system analysis, accounting-constructive, statistical, experimental, economic and mathematical modeling. Theoretical and practical results - Designed theoretical and methodical positions allow motivating the rational structures an electro drive, source requirements on parametric row without reduction electro drive of the agricultural machines, which confirmed MAP of Ukraine. The scientific developments are used in scholastic process and research work. Novelty - is unscrewed method of the motivation economic efficient parameter electro drive of the agricultural machines, which is based on prior to work methodical positions of the determination technician-working factors and technical-economic model electro drive. At determination of the energy factors electro drive is taken into account change coefficient of efficiency and factor to powers not only electric motor, but also mechanical transmission, loss in which, as a rule, earlier were not taken into account. It is designed mathematical models without reduction electro drive of the agricultural machines, which enable to value the technical-economic features possible variant electro drive and install practicability of their using. In installed parameter and structure new electro drive agricultural machines, in dependencies between value of the economic effect and power of the electric motor with built-in protection, imaged efficiency of the use the electric motors of the special purpose. The sphere of the use - agroindustrial complex.
