INDUCTION MOTOR UNDER PULSED LOADS
An induction motor is subjected
to a pulsating step load ranging from quarter to full load. The motion of the machine variables
viewed as phasors or space vectors (in the synchronous frame) is exhibited in
this clip. The input voltage V is chosen as
reference; the stator and rotor currents and the stator and rotor fluxes are
shown. Also plotted are the corresponding torque-speed dynamic characteristics.
