What else can I help you with?
Is the speed of travel of electricity in a conductor less than or equal to the speed of light?
Nothing is faster than the speed of light.
What is the unit of measure for magnetic induction?
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.
What is mean by slip power?
Slip power is the electrical power that is converted into mechanical power due to the slip between the stator magnetic field and rotor in an induction motor. It is the power required to maintain the rotor's rotation at a speed slightly lower than the synchronous speed of the stator field.
Why does it take Venus quicker than earth to orbit the sun?
Because Venus has less distance to travel, and it has a faster orbital speed than the Earth.
If I was riding a bike inside a bubble at 4 mph and the bubble was travelling at the speed of light when i turned on the front light on would the light shine in front or behind the bike.?
You cannot go at or faster than the speed of light. Let's say your bubble was going 2 mph less than the speed of light. The way relativity works, you could ride your bike at any speed humanly possible, from your point of view. But your time is slowed down, so from an outside observer, you appear to only move slightly faster (still less than light speed). And if you turn on that flashlight, it will go away from you apparently at light speed, but the outside observer will also see it moving at light speed. It is tricky when you first encounter this.
How do you slow down the speed of a conveyor belt?
Money drives the rotor is smaller than the velocity of money is less.
Difference between induction motor and induction generator?
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.......
Why is it impossible for induction motor to operate at synchronous speed?
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.
Why sleep is occurs in three phase induction motor?
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.
Explains why a 3-phase induction motor develops no torque when running at synchronous speed?
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
Why induction motor does not runs at synchronous speed?
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.
Why does the rotor of an induction motor turn slower than the revolving field?
In an induction motor the rotor currents are induced by the magnetic field of the stator, and if the motor were to run at synchronous speed the induced currents and also the torque would fall to zero. The rotor currents alternate at a low frequency determined by the 'slip', which is the percentage amount that the rotor speed is below the synchronous speed. The output torque is proportional to the slip at near-synchronous speeds.
When acceleration is less than 0 and velocity is less than 0 then speed is?
When acceleration is less than 0 and velocity is less than 0, the speed is positive. Speed is the absolute value of velocity, so it is always positive regardless of the direction of motion.
Minimum brake rotor thickness for a 2003 Mitsubishi Eclipse GTS?
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.
Is it average speed greater than or less than a cheetah?
Less than . :) Karls(:
Isuzu Rodeo rear rotor thickness?
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.
