The current is typically highest in a three-phase induction motor during startup, when the motor is initially energized. At this point, the motor is at standstill, and the slip is 1 (or 100%), leading to maximum current draw from the power supply. Once the motor accelerates and reaches its rated speed, the current decreases to a stable operating level, which is significantly lower than the starting current. Additionally, high currents can also occur during overload conditions or if there is a fault in the motor or supply system.
What else can I help you with?
How does the 3-phase induction motor acts like 2-phase induction motor if a phase is disconnected from supply?
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
Is 3 phase induction motor is self starting?
Yes, that is one of the major advantages of a three-phase induction motor.
Self starting single phase induction motors are also called?
Split Phase Induction Motor.
How do you start single phase induction motor?
capacitive start motors start by themselves however a normal single phase induction motor requires a starter motor to 'kick-start' the motor into action.
Why one phase shows 0 Amps while a delta connected 3 phase induction motor runs?
Cause 2 phase is applied to the motor and another phase is disconnected ... in this condition ur motor cannot run longer ,it will trip on over current or burn ur motor winding .

Applications of induction motor?
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
How single-phase induction motor classified?
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
How many poles are required on motor starters for the following motors a240-volt single-phase induction motor b440-volt three-phase induction motor?
For a 240-volt single-phase induction motor, a two-pole motor starter is typically required, as it connects to the two live conductors of the single-phase supply. For a 440-volt three-phase induction motor, a three-pole motor starter is needed, as it connects to the three phases of the three-phase supply.
Self starting single phase induction motors are also called?
Split Phase Induction Motor.
What motor is used in a fan?
Single phase Induction motor
