Can 3 pH induction motor rotates if its 1 winding get shorted?
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.
How do you know if a three phase motor's winding is shorted?
You use a megger. This allows you to check what the condition of the insulation of the motor windings are. An ohms check on each phase should be an easy way if it reads OPEN then there's your bad phase. Otherwise there are diffrent types of 3 phase motors, could be the brushes, commutator, sliprings, many many things.
What happens if field winding of a running dc shunt motor suddenly breaks open?
when the field winding of a running dc shunt motor suddenly breaks open the motor fails to run because in the motor the stationary winding is armature and rotatory is field winding
What is the function of winding in motor?
because its winding follows the wave sign
If the running winding and the auxiliary winding were connected in series would the motor run?
no

What is a shunted winding?
A winding that has several coils shorted together.
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.
How is the synchronous motor made self starting?
The synchronous motor is made self starting by providing a special winding on the rotor poles, known as damper winding or squirrel cage winding. AC supply given to the stator produces a rotating magnetic field which causes the rotor to rotate, therefore, in the beginning synchronous motor provided with damper winding starts as a squirrel cage induction motor. The exciter moves along the rotor. When the motor attains about 95%of synchronous speed, the rotor winding is connected to exciter terminals and the rotor is magnetically locked by the rotating field of the stator and the motor runs as a synchronous motor. While starting a synchronous motor, the field winding must be shorted through a suitable resistance so that the induced voltage is distributed throughout the whole winding and no part is subjected to the high voltage induced in the entire winding.
How do you check a motor for a bad winding?
You need a Megger tester. With one lead attached to the winding and the other attached to the motor housing, the Megger sends a high voltage through the winding. The Megger reads the resistance, letting you know if there is a short to ground.
How is the resistance of a motor winding expressed?
The resistance of a motor winding is expressed in
Why a 750 kw motor takes 17 amps starting current?
The starting current is high because the motor's rotor winding has very low resistance. It's similar to a transformer with a shorted secondary windings. As the motor accelerates,the back emf increases which resist the flow of current in the rotor winding. Hence,the current drop to the rated full-load value.
How can you test a compressor to see if it has shorted?
You would need to put an amp-meter on the circuit to see what the current draw is like. ====== If the compressor is shorted to ground you cannot check the amp draw because it will constantly kill the circuit breaker. A better way to go would be to check the continuity of the compressor to ground and each winding.

The function of a start winding in a split-phase motor is to?
a start winding on a motor is used to add torque to start a motor, and more importantly to establish the direction that the motor will turn. to reverse a motor normally means to reverse the start winding. the run winding will work the same in either direction, the start winding determines the direction.
