Field assessment of induction motor efficiency
... In Method E the input power is used as the base to subtract various losses for the output power. The negative sequence losses that are mostly not covered by the no load loss increase the input power. Subsequently, the output power is higher. On the contrary, the air-gap torque method uses the air-ga ...
