Sports and Recreation Vehicle UTV
Opis:: Traction calculations of the Sports and Recreation vehicle fitted with a permanent magnets electric motor with a capacity of 15kW are presented in the paper. The calculations of ability to overcome the motion resistance of the car and capable of speeds and accelartions at different ratios are shown. The necessary improvements to mount the electric drive and good points of this solution are discussed. The traction calculations comparison of the electric motor with internal-combustion engine will be shown in the next part of article.

Opis:: The Ecca Group, a subdivision of the Karoo Supergroup (Upper Carboniferous - Lower Jurassic) in SW Botswana is a sequence deposited as marine deltaic bodies considered to have been supplied from a cratonic source elevated north of the basin. The Karoo strata in this region are covered unconformably by sands of the Kalahari Beds (Upper Cretaceous - Recent). Therefore the bedrock outcrops are extremely rare, limited in size and a low number of boreholes drilled in this vast area (ca. 340 x 540 km) provide the only insights into the succession of the Karoo Supergroup. Very long distances between individual boreholes make correlation, interpolation between localities and interpretations of geometry of lithological bodies that would provide clues supporting basin analysis by traditional means problematic. To achieve the first approximation of the space-time relations between lithologically complex Ecca Group lithofacies associations modelling of these sediments using Petrel software was performed. These relations in turn suggest evolutionary trends of the basin during deposition of the Ecca Group strata. The model suggests two main zones of supply indicated by two distinctly different patterns of deltaic lithofacies associations, and their evolution controlled by post-Dwyka palaeotopography and its subsequent modifications by local subsidence in the centre of the depository. Initially rapid southward progradation of relatively fine-grained delta body located in the west of the area was followed by subsidence-induced aggradation interrupted by stages of abandonment and marine transgression. Such variations, emphasised by the presence of sandy clinoforms of the delta lobes separated by basinal "fines", imply significant interplay between rates of supply and subsidence. On the other hand, the delta formed in the east contains relatively high proportion of coarse-grained sandstone facies overlying prodelta fines as laterally extensive tabular body formed most probably by lateral migration of distributary channels and delta-front mouthbars, and devoid of abandonment stages. Proximal litofacies of the "western delta" fill the subsiding depocentre and grade distally into synchronously deposited prodelta fines towards the south. By contrast, distal fine-grained prodelta facies fill basin depocentre in the eastern area and are overlain by proximal facies of the "eastern delta".

Opis:: The paper deals with the modern variable-speed electric drive named E-Kit, dedicated to electrification of used small passenger cars with combustion engines. The main assumptions taken into account when designing E-Kit drive are described in the paper. Main electrical parameters and electromechanical characteristic curves of Interior Permanent Magnet Synchronous Motor dedicated to E-Kit drive are presented. On the IPMSM motor's electromechanical curves two speed control zones are distinguished and described: constant torque zone and constant power zone. Mechanical construction of this motor is also described shortly. In the paragraph 5 the results of traction calculations and appropriate traction characteristic curves of E-Kit drive are presented.
