can we run 3 phase induction motor under 2 phase supply
Answer Posted / raj varpe
IM WILL RUN AT TWO PHASE BUT WHEN 1 PHASE IS AT ZERO
AMPLITUDE & OTHER AT NEGATIVE MAXIMUM IT WILL CAUSE A
MOMENTERILY JERK ON MOTOR CHANCES OF REVERSAL OF DIRECTION
TIME AFTER TIME & VIBRATIONS ARE MORE & EFFICIENCY DECREASES
