What is the relationship between torque and angle?
loj
What is the relationship between axis of rotation and center of gravity?
The greater the distance from the axis of rotation (i.e., pivot point) to the center of gravity of an object, the greater the torque required to rotate the object.
What is the relation between torque and angular momentum?
Torque is the rate of change of angular momentum.
What is difference between speed and torque?
speed= distance per seconds & torque= revolution per seconds
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.
What is the relationship between torque and angle?
loj
What is the relationship between torque and speed for an electric motor?
Torque and speed are inversely proportional
What is the Relation between power factor and slip?
inversely proportional relationship
What is the torque speed characteristic?
the ratio of the relative speed of stator magnetic field with the speed of rotor, to the speed of rotor is defined as slip. where as in torque slip characteristic is the graph between the speed of the rotor and the torque experienced on the rotor. in the case of induction motor, the torque decreases with the increase in the rotors speed. while in the case of sychronous motor, its different (you check out, because i just forgot about it!! keep smiling!
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 three factors determine the amount of torque produced by an AC induction motor?
Torque is produced by a phase difference between two windings. The higher the phase difference, the higher the torque.The rotor rotates slightly slower than the magnetic field produced by the stator (the fixed winding). The difference in speed is called the slip and it allows low-frequency currents to be induced in the rotor and torque to be produced. For a motor rotating just below the synchronous speed, the torque is proportional to the slip which is defined by this, where Nis the actual speed and Ns is the synchronous speed:s = 1 - N/Ns
What is the importance of slip in a 3-phase induction motor?
Slip is a measure of the difference in relative motion between the rotor and the magnetic field set up by the field windings.In very simple terms, without slip an induction motor would not be able to develop any torque! A slip of zero means that the rotor is turning at synchronous speed; in other words it is running at the same speed as the rotating field set up by the field windings, so there is no relative movement between the field and the rotor. To develop torque, the voltages must be induced into the rotor, and this can only happen if there is relative movement between the field and the rotor -in other words, the rotor MUST be running more slowly than synchronous speed. That is, there must be some degree of slip.
What is the difference between slip and slide?
what's the difference between slip and slide
Where is the torque converter on a 1999 Buick Le Sabre?
The torque converter is between the engine and transmission.The torque converter is between the engine and transmission.
What is slip and slip motor?
the difference between the synchronous speed and actual speed is called as slip
Why is the best to use Philip type screwdriver?
Less likely to slip so more torque can be applied
