It is currently difficult to find industrial or any other process, that does not use induction motors. For economical and efficient management of the latter are widely used frequency converters for induction motors, is an ideal device for automated control systems of various technological processes. Wide range of speed control speed motor, high precision to maintain it at steady speeds, smooth starting and stopping of electric power save mode – this is just a small list of advantages of variable-frequency actuator. To achieve the maximum economic benefit from the use of frequency converters for induction motors, they are recommended to implement those processes, where: – the number varies output per unit of time – you want to smooth adjustment of the parameters of a workflow mechanism – changes the type or structure of the source material for different types of products – technological equipment, pumps, fans, compressors operate with a variable, or part-time – need frequent start, stop, reverse drive motor, leading to increased stress on equipment and electric, to waterhammer in pipelines shall be reduced, ultimately, their life – has overrun power In the Russian market popular following inverters frequency converters Vesper, transformers Frequency Delta, inverters Lenze. Frequency converters Converters Vesper Vesper – one of the most popular on the market and have several advantages over imported frequency converter. – E2-MINI: recommended for mechanisms with constant torque or resistance to the fan load and can be used to drive sewing machines, low-power pumps and compresses on conveyors with low productivity with the engine capacity of 0.2 kW to 2,2 kW Name Pdvig kW Iout nom., A Upow., B .maks., B WxHxD Weight E2-MINI-002H 1,5 3,8 3f.h380 3f.h380 118h143h172 1,7 E2-MINI-S2L 1,5 7,5 1f.h220 3f.h220 118h143h172 1,7 E2-MINI-S3L 2,2 10,5 1f.h220 3f.h220 118h143h172 1,7 E2-MINI-003H 2.2 5.2 3f.h380 3f.h380 118h143h172 1,7 – E2-8300: recommended for drives with a constant, fast-changing and Fan load: Conveying Equipment, Conveyors, conveyors, extruders, cutters, packaging and dosing machines, separators, etc.
