Abstract

Several electric drive systems can satisfy the technical requirements of various production mechanisms. The final choice is made by economic evaluation. Modern systems of adjustable electric drive have a stepwise schedule of load and speed, which significantly complicates the economic assessment. It is recommended for an approximate economic assessment to result in a stepwise graph of load and speed to two equivalent, where the load and speed are equal to the mean and root-mean-square values. The error does not exceed 15% for low power drives. The ratios for determining the areas of modes of operation with minimal costs and a graphical method for determining the costs and payback period of the systems of an adjustable electric drive are given. Ill. 2, Bible. 3
