Abstrakt CZ: Pulzační ztráty v asynchronních strojích je velice obtížné určit, tato práce se zabývá metodou, která toto umožňuje.
Abstrakt EN: Pulsation losses, which are very difficult to measure, are present in every squirrel cage induction motor and depend mainly on the geometrical design. A two-step method for computing the iron losses in a squirrel cage induction machine is proposed. As a first step the flux density in the cross section of the motor is evaluated using a FEM model neglecting hysteresis and eddy currents in the laminated core. The second step is practically the usage of equations computing both iron and eddy current losses
