Opis:: Time-related accident risk in shift work may be attributed to internal factors, such as fatigue, level of performance, sleep propensity, and to some external factors, like shift system, physical and social environment. Six hundred and sixty-eight events in the metallurgical industry have been analysed in terms of time of day, time on task, consecutive day of the shift block, day of the week, and season. The injury rate was similar on all shifts but more severe accidents happened in the nighttime. Somewhat more injuries occurred in the second half of the shift, in the second part of a shift block, and in summer compared with winter. There were fewer injuries at weekends.

Opis:: Assumptions and final structure of series motor equations were presented. In the description, a magnetization curve, which significantly affects properties of the motor, was taken into account. Nonlinearly connected with magnetization curve is present in a induction voltage drop and in a rotation voltage, as well. Quantitive examinations were performed for a series motor PBSOa12x type. A share of current dependent induction voltage drop components was examined. It was assumed that additional, so-called “negative inductance”, which is a product of a current and partial, current derivative of inductance, can be omitted. This conclusion can be regarded as general. It refers to a typical motor taking into account construction and magnetic materials. So-called incremental equations of a motor were formulated, which describe it behaviour in a small deviation from an equilibrium point. Using a precise model, a simulation of a motor start fed from a DC controlled rectifier was performed. The simulated system was a closed one with a current limitation. The feeding voltage was an input signal.
