according to a mathematical theory the flux produced when an alternating current flows in a single phase winding , this flux is composed of tow equal components which result in tow equal torques , these torques work in opposite direction to each other , hence one causes the rotor to move in a certain direction while the other in the opposite direction . this is the reason why a single phase induction motor instead of its rotor to move in one direction it vibrates. the resultant of these torques is zero. if the motor is caused to move by an external mean say by hand , then the resultant will no longer zero and the motor continue revolving and it speeds up even the external mean is removed,
For a single phase induction motor to be a self starting motor some techniques are used like connecting an additional winding called auxiliary winding and a capacitor which in some designs removed automatically when the motor speed come to a certain value while for other designs these elements continue to be connected . Any single phase induction motor is provided by a starting technique so if it vibrates , then this means that the technique is failed

What is a CSIR motor?
A CSIR motor stands for Capacitor Start-Induction Run motor, which is a type of single-phase induction motor commonly used in household appliances like refrigerators and air conditioners. It uses a capacitor to provide the starting torque needed to initiate rotation, then operates as a standard induction motor once up to speed.
Full load torque of induction motor?
The full load torque of an induction motor is the maximum torque it can produce at its rated speed when operating at full load conditions. This torque is necessary to drive the load at the desired speed under normal operating conditions. It is an important parameter to consider when selecting a motor for a specific application.
What type of motor is used in table fan?
Table fans typically use an AC induction motor, which is cost-effective, efficient, and reliable for driving the fan blades. The motor is designed to provide the necessary torque and speed for the fan to effectively circulate air in a small space.
What is the break drum radius for a single phase induction motor?
The correct spelling is 'brake' rather than 'break', but the 'drum' you refer to is used when testing the output power at the shaft of an induction motor. The diameter will depend on the power of the motor, and the test equipment used. 'Brake power' refers to the output power of the machine measured in watts or, in the United States, in horsepower. If you know the output power (by conducting this test) and the input power (using a wattmeter), then you can determine the machine's efficiency.
Why does my 12 volt direct current motor stutter when i connect it to a pulsating 12 volt direct current power supply?
Your 12-volt direct current motor may stutter when connected to a pulsating power supply due to irregular voltage levels that prevent the motor from receiving a consistent flow of power. Pulsating DC can lead to insufficient torque, causing the motor to struggle to maintain its speed and leading to stuttering. Additionally, the motor might not be able to handle the rapid fluctuations in voltage, which can result in erratic behavior. To resolve this, consider using a stabilized power supply that provides a smooth, constant voltage output.
How pulsating torque can be removed from one phase induction motor?
The only way is mechanical - use a heavy flywheel.
What are the advantages of single phase induction motor?
the torque requirement of single phase induction motor is less,and it is use for low power applications upto 1 to 10 kw.like in fans,mixiers
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
What is the maximum torque than an induction motor can develop known as?
Gross Torque
Performance curve of a single phase induction motor?
The performance curve can be a graph of torque versus speed. The torque is zero at zero speed and also at the synchronous speed. Normally an induction motor operates at 90-97% of the synchronous speed, where the slip is between 10% and 3%. In this region the torque is proportional to the slip. As the torque is increased the speed falls until the motor stalls and the speed drops to zero. Below the stalling speed the torque rises between zero speed and the stalling speed. Because the torque is 0 at 0, a single-phase induction motor needs a separate starting winding fed by a starting capacitor to produce a little positive torque that starts the motor.
What is the function of a capacitor in an induction motor?
It provides the phase shift necessary to have a rotating magnetic field for the rotor to spin. Answer #2: single phase induction motor can create pulsating magnetic field. due to single phase forward and backward torque created also they cancel led each other.so we want to extra force to rotate rotor either forward or reverse direction or we can give rotating magnetic field by using capacitor(phase split)
Why use clutch plate in single phase motor?
induction motors have very little starting torque as the motor come up to speed it reduces the torque load until it gets near synchronous speed
How does an induction motor develop torque?
The shaft of an AC induction motor rotates because of the torque created by the interaction between the magnetic field of the stator and the magnetic field of the rotor.
What are the advantages of induction motor?
1. Induction motor has high starting torque, therefore use for operate pump which need high starting torque. 2. Induction motor operate on variable speed. 3. It can be used as generator when speed of motor is higher than synchronous speed.
