| Abstract |
This paper presents a circuit model of permanent
magnet brushless direct current motor in which it is possible
to simulate the phase open circuit faults and access the
center of star-connected three-phase winding. The remedial
strategies are introduced for the open-circuit of phase and
power switch disconnection. The control system with two
added electronic switches to the inverter can control the
faulty motor such that a positive desired torque is
developed. In this method a single phase is excited during
the fault over some periods. The output of the faulty motor
is lower than that of the healthy motor. |
