ABSTRACT
This
paper explores dynamic behaviors of asynchronous motor under intermittent
loading based on finite element models and solutions in time domain. Transient
Finite Element Analysis (FEA) of the motor in an on and off loading conditions
is performed at time intervals of 0.2s for a 2D model. Dynamic characteristics
such as speed, torque, phase currents and flux distributions of the motor were
studied. It was observed that at the 37 Nm rated load, the motor recorded a
negative speed when loaded intermittently at 0.2s intervals. The maximum load
for which positive speed was observed is 32 Nm. The other characteristics were
in acceptable ranges for both loads.
Keywords: Finite Element Analysis (FEA), induction motor, intermittent loading, magnetic flux distributions and movement band
