Question:medium

In torque-slip curve of a 1-$\phi$ induction motor, the backward torque is

Show Hint

In double revolving field theory, the backward torque opposes the forward direction of rotation across all normal speeds. This means its sign remains consistently negative throughout the entire slip range from $s = 0$ to $s = 2$.

Updated On: Jun 25, 2026

$ \text{negative from slip s=0 to s=1 and positive from slip s=1 to s=2} $
$ \text{negative from slip s=0 to s=2} $
$ \text{negative from slip s=0.5 to s=1.5} $
$ \text{negative from slip s=1 to s=2 and positive from slip s=0 to s=1} $
