← TechnologyWhich outcome occurs when an asynchronous AC induction motor is directly connected to the electric grid without a soft starter?
A)Reduced mechanical wear on bearings
B)Brief voltage sags on grid✓
C)Improved motor speed regulation
D)Decreased stator winding temperature
💡 Explanation
Voltage sags briefly occur due to **inrush current**, because the motor attempts to draw significantly more current than usual during startup to overcome its inertia; therefore a voltage sag appears in nearby loads rather than improved conditions within the motor.
