constant, is aluminum, for which Formula (6.7) makes it possible to evaluate theoretically acceptable values of . For example, if one creates in the gap a magnetic inductance of for an aluminum rotor and the following coefficients: ; then The actual values of for the electromagnetic brakes with a full rotor and with permanent magnets, for which the magnetic inductance is (Table 6.1). Table 6.1. Parameters of electromagnetic brakes a. docking device; b. momentum at , N-cm; c. slope of the momentum characteristic N cm s; d. time constant, ms; e. maximum velocity w”, rev/min-103; f. maximum power, kW; g. moment of inertia; h. magnetic system; i. material; j. maximum energy kJ/m3; k. magnetic inductance of gap, T; 1. mass, kg; m.

For example, in the application of a constant force a damper velocity is established which reaches in exponent where is the current time. The absolute value of
