The work presented calculation and measurement results of a small power (1.5 kW) squirrel cage motor, thus verifying used for calculation two-dimensional circuit- field motor model. Using the prepared model, calculations of static (no load, load and locked rotor) characteristic as well as dynamic ( start up to no load) were compiled. Convergence of calculated and measured characteristics results varies for different motor work states. It is a result of an employment of approximations in two-dimensional circuit-field motor model as well as of varying measurement conditions. Assumed for calculations speed and temperature stability cannot be maintained in the measuring conditions. The calculating model assumption of constant parameters of stator winding frontal connections and squirrel cage ring, causes that such diverse motor work states as no load and locked rotor, could not be precisely calculated at the same time. None the less good consistence of calculated and measured results, for the full motor operating range, is obtained by assumption of mean values of inductivity and frontal connection . It may be therefore accepted, that the described model is useful in evaluation of events occurring in different states of motor operation.
