Squirrel Cage motor is a kind of Induction Motor. The reason an induction motor sometimes refered to a rotating transformer is because the stator (Primary windings in a transformer), which is powered to set up a magnetic field induces a current in the armature coils (secondar coils in a transformer). However, instead of giving an electrical power output, the coil is short circuited to produce mechanical output (torque in this case)
What else can I help you with?
What are the cause a dc motor fail to start?
A DC motor may fail to start due to several reasons, including inadequate power supply or voltage, which prevents it from receiving sufficient current. Additionally, issues such as worn-out brushes, a damaged commutator, or internal short circuits can impede operation. Mechanical obstructions or excessive load can also prevent the rotor from turning. Lastly, faulty connections or wiring issues may disrupt the electrical flow needed for startup.
What have Tool got to do with Short Stack?
cuz short stack are tools :D
Why compressor using time delay?
A time delay in a compressor is used to prevent short cycling, which can lead to increased wear and tear on the compressor and reduced efficiency. By allowing a brief pause between cycles, the system can stabilize pressure and temperature, ensuring optimal performance. Additionally, this delay helps to protect the compressor's motor from overheating and enhances the overall lifespan of the equipment.
Why is short bead in welding on mild steel and high tensile steel are to be avoided?
Short bead as well as arc strikes create a sudden localized temperature increase to the metal and can cause cracking.
What simple machine does a chisel resemble?
A chisel resembles a short wedge.
Which cell is damaged by short circuiting?
Any cell may be damaged by short-circuiting.
What is the neccesity of short circuiting the rotor conductors of sci?
Short circuiting the rotor conductors of a squirrel cage induction motor (SCI) is necessary during testing and maintenance to ensure safety and prevent damage. It allows for the safe discharge of any residual electrical energy and helps in diagnosing issues within the motor by simulating fault conditions. Additionally, this practice helps to eliminate potential electrical hazards and reduces the risk of electrical arcing during maintenance activities. Overall, it is a crucial step in maintaining the motor's operational integrity.
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 can cause the 2000 Toyota Sienna power door locks fuse to keep blowing?
It could be short-circuiting or intermittent short-circuiting of wires to the power door motor.09/22/10--- take it to a body shop, have them reprogram the power door computer for $75 Toyota gave me BS about needing to replace everything for over $1000.
How do you start a single phase slip ring induction motor?
a single phase motor must have at least 4 poles one set is connected to the line the other is connected in series thru a capacitor or inductor to shift phase and set up a rotating magnetic field the rotor usually has a squirrel cage that will start turning the slip rings can have different purposes depending on how the rotor is wound if the highest rpm of the motor is a multiple of the line frequency 3600RPM for 60Hz 2 pole you apply dc to the winding to make it synchronous. if the hi speed of the motor is 3470RPM the squirrel cage is weak and you must short the rings to get up to the high speed there is beauty in this in that if you vary the resistance from short to open it will be a variable speed motor
Why vertical polarization cause short circuiting in receiver?
Why vertical polarization not working in receiver
Will a battery explode when short circuiting the battery?
Yes it could over heat and explode. Don't do it.
What is ment by the term short circuit?
Short circuiting means providing a low resistive path, diverting maximum current away from where it was intended to go.
What is the duration of Rings short film?
The duration of Rings - short film - is 960.0 seconds.
What is meant by thermocouple short circuiting?
Thermocouple short circuiting refers to an unintended electrical connection between the two dissimilar metal wires that form a thermocouple, which can lead to inaccurate temperature readings. When the wires touch or are connected improperly, the thermoelectric voltage generated by the temperature difference is disrupted, potentially resulting in a reading of zero volts or erroneous temperature values. This can occur due to physical damage, insulation failure, or poor connections. Proper installation and regular maintenance are essential to prevent short circuiting and ensure accurate temperature measurements.
Why it is not possible to insert the external resistance in the rotor circuit in a cage induction motor?
A squirrel-cage rotor consists of uninsulated copper or alumnium bars, short-circuited by rings located at opposite ends, and semi-enclosed within a laminated iron rotor, and there is no provision for any form of external connection. So it would be quite impractical to do what you suggest.
