Abstract
Squirrel cage induction motors have wide range of applications in many industrial
drive systems due to their simple construction, robust design and low operational costs. Their
application becomes even wider as a result of implementation of voltage inverters providing
very good speed-torque control characteristics. In this paper a dynamic behaviour of a squirrel
cage induction motor type 2AZ 155-4, produced by Rade Koncar, is analysed. The motor has
the following rated data: voltage (Δ/Y) 220/380 V, number of poles 2p=4, rated current 8,7/5
A, power factor cosϕ=0,81, rated speed nn=1410 rpm, frequency 50 Hz. The first simulation
motor model, supplied from a symmetrical power supply, is developed in MATLAB/Simulink
[1]. The following dynamic motor characteristics, such as: speed characteristic,
electromagnetic torque characteristic and current were obtained from this model. Than the
analysis is extended with a simulation model of the motor fed by a voltage inverter. In this
case the motor transient speed, current and electromagnetic torque characteristics are
obtained, for rated frequency as well as for frequencies lower and higher than the rated one.
The results obtained from the simulation in MATLAB/Simulink are compared and verified
with the results from the second simulation model developed in the software program PSIM.
Distribution of magnetic flux density inside the motor cross section is gained by application
of the Finite Elements Method (FEM) for all motor operation regimes.
