Nothing is faster than the speed of light.
One of the most common electrical motor used in most applications which is known as induction motor. This motor is also called as asynchronous motor because it runs at a speed less than synchronous speed. In this, we need to define what is synchronous speed. Synchronous speed is the speed of rotation of the magnetic field in a rotary machine and it depends upon the frequency and number poles of the machine. An induction motor always runs at a speed less than synchronous speed because the rotating magnetic field which is produced in the stator will generate flux in the rotor which will make the rotor to rotate, but due to the lagging of flux current in the rotor with flux current in the stator, the rotor will never reach to its rotating magnetic field speed i.e. the synchronous speed.
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
There's no such thing. Or, rather, it depends on the circumstances. It has to be less than the speed of light in a vacuum, but other than that restriction, it can be almost any value (including faster than the speed of light in the medium it's traveling in, in which case it emits Cerenkov radiation).
The speed of light through vacuum is constant. The speed of light through air is slightly less. The speed of light through water or some other medium is even less than that. The factor by which the speed of light (and its wavelength) is reduced within a medium is called the "index of refraction" (which determines the amount of bending that occurs when light goes from one medium to another).
Money drives the rotor is smaller than the velocity of money is less.
in case of induction motor the rotor speed is less than synchronous speed giving positive slip but in case of generator the rptor speed is greater than synchronous speed giving negative slip.......
Torque is produced because the rotating magnetic field, set up by the stator windings, cut and induce voltages into the rotor bars. The fields set up by the resulting rotor-bar currents then interact with the rotating field, causing the rotor to turn. If the rotor turns at the same speed as the rototing field, then its bars will not be cut by the field, there will be no induced voltages, no bar currents, and the torque will disappear.
Slip is the relative difference between the speed of the rotating magnetic field of the stator windings and the speed of the rotor. The rotor must always run at a speed lower than the synchronous speed otherwise the rotor windings will not be cut by the magnetic field and hence no induced emf,no torque and the rotor will stand idle.
When rotor speed becomes equal to Synchronous speed in an induction motor, it means that the slip is zero. Which means that there is no cutting of magnetic lines by rotor bars and hence no torque is generated. To generate Torque, rotor speed should always be less than the synchronous speed. That is why, you must have seen in your dailty life that all induction motors are rated below 3000 RPM(sync speed for a 2 pole machine). Sync speed (Ns) = 120f/P
An induction motor cannot run at synchronous speed because it is the "slippage" of the rotor relative to the rotaing magnetic field that generates the current in the windings contained within the rotor. This induced (hence the term induction) current sets up the opposing magnetic fields that cause the rotor to rotate.
The brake rotor thickness for your 2003 Mitsubishi Eclipse, is 0.75. The rotor should not be used if the thickness is less than this.
Less than . :) Karls(:
Its initial speed is less than its final speed.
The rear rotor thickness should be three quarters of an inch, when new. The rotor should not be reused when the thickness is less than one half inch.
why the lan high speed than wan
if the motor is at synchronous frequency there is no current induced in the shorted windings in the rotor so at no load its slightly less. if you drive the motor faster than synchronous speed it becomes a generator
