If one winding of a three-phase induction motor gets shorted, the motor may still operate, but its performance will be significantly affected. The shorted winding can cause an imbalance in the magnetic field, leading to reduced torque and efficiency. In some cases, the motor may overheat or get damaged due to the increased current in the remaining windings. Therefore, while it might rotate, it is not advisable to operate a motor with a shorted winding.
What else can I help you with?
What is the useful of open end winding of induction motor?
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.
Which motor doesn't have any winding on its rotor?
Squirrel cage induction motors.
How can you reverse the direction of rotation in an induction motor?
A single phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.
Do all single phase motors have a start and run winding?
No, commutator motors as used in vaccum cleaners for example do not use a starting winding. Single-phase induction motors need a starting winding without which they will start in either direction if given an initial twist.
Why 3 phase induction motor is self starting but synchronous motor is not?
the induction motor as soon as you turn on the power the rotating magnetic field is set up. the shorted winding in the squirrel cage see this and builds up a temporary magnet when its up to synchronous speed there is no longer current in the shorted winding in a single pole motor 60hz this speed is 3600 rpm depending on coupling and skew induction motor is always less than synchronous speed. the synchronous motor as soon as you turn on the power the rotating magnetic field is set up the permanent magnet 0 to 3600 rpm in 1/60th of a second this requires all the power you can deliver until you reach synchronous speed a bit hard on the power source smaller synchronous motors sometimes have a squirrel cage and permanent magnets and enough impedance so they dont put a heavy load on the power electric clocks have the shorted windings on the poles self starting hi impedance some older electric clocks didnt have the shorted windings and need to be nudged to get then spinning
Does induction motor has rotor winding?
Yes, the induction motor has a rotor winding. It is usually one turn, shorted. This is how the magnetic fields generated in the stator induce a current in the rotor, which subsequently generates a torque from the opposing magnetic fields, stator to rotor.
Will a induction motor run on one winding once it has been started?
A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.
Will a single-phase Induction motor run on one winding once it has been started?
A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.

When will a synchornous motor acts as an induction motor?
If there is an extra winding called the "damper winding" in addition to the field winding.Then the synchronous motor will operate as a squirrel cage induction motor.Whats is a damper winding ?A damper winding is made up of copper bars which are placed in the slots in the pole faces of the rotor.These are short circuited with the help of end rings in a squirrel cage induction motor.
What is the useful of open end winding of induction motor?
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.
Polarity of six terminal induction motor winding is decided at the time of connection of winding?
Is there a question here.
Why induction motor is also called short circuit transformer?
Like transformer induction motor has stator winding(Primary winding) and rotor winding(Secondary winding) separated by an airgap.Rotor winding(generally Al bars) are short circuited at the end to produce torque for the rotation.Hence the name short circuited transformer.
Why you have to connect DC supply to the induction motor?
To start an induction motor we have to excite field. The excitation is done by connecting the DC supply to the field winding's.
Which motor doesn't have any winding on its rotor?
Squirrel cage induction motors.

Will a singl phase induction motor start if only the running or the starting winding is excited?
No.
