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 .

Are contactor points and bimetallic strip connected to the star delta starter of 3 phase induction motor?
yes
Condition of three phase in which there is no need of neutral?
A delta-connected system is described as being a three-phase, three-wire, system, and doesn't have a neutral. But a balanced star (wye) connected load (e.g. a three-phase induction motor) doesn't actually require a neutral.
How do star and delta configured three phase induction motors perform differently?
Star Delta starter control wiring ensures that initially the Motor winding is connected in Star and after set timer (few seconds) the winding gets connected in Delta automatically. There three power contactors and timers to make it happen.
Will a 3 phase motor work on grounded B phase?
If the motor is connected to an ungrounded delta supply service there will be no effect on the operation of the motor. If the motor is connected to a wye system supply service and the B phase grounds out, the motor's overload protection would take the motor off line from the electrical supply.
Is 3 phase induction motor is self starting?
Yes, that is one of the major advantages of a three-phase induction motor.
Theory for brake test on three phase induction motor?
why three phase induction motor is delta connected
Are contactor points and bimetallic strip connected to the star delta starter of 3 phase induction motor?
yes

A delta connected 3 phase motor, shown above, draws a line current of 24 A from a 400 V supply, If fuse F3 blows, determine the current in each phase winding of the motor.IA = IC = IB=?
For proper working of any 3 phase induction motor it must be connected to a 3 phase alternating current (ac) power supply of rated voltage ...

If the motor is connected to an ungrounded delta supply service there will be no effect on the operation of the motor. If the motor is connected to a wye system supply service and the B phase grounds out, the motor's overload protection would take the motor off line from the electrical supply.
Why each phase no load power factor of 3 phase induction motor is not same?
That indicates a fault in the induction motor.
Is 3 phase induction motor is self starting?
Yes, that is one of the major advantages of a three-phase induction motor.
What type of induction motor is used in water pump set?
3 Phase induction motor is used in water pump set.(K.W-5.5,V-415,AMPS-CONN 10.35 DELTA,RPM-1450). Use for domestic pumps only 2 phase
How do you reverse single phase ac motor to generator?
