What is a 3 phase torque?
It is a short-hand description of the torque from a 3-phase motor. By the nature of 3-phase electricity, a motor using it gives a constant torque, unlike a single-phase motor which gives a torque that pulsates at twice the supply frequency. Usually that does not matter because there is enough inertia in the rotating parts to mask the effect.
Why is the relationship between torque horsepower and RPM not linear In automobile terms.?
The relationship between torque, horsepower, and RPM in an automobile is not linear because torque and horsepower are related through the equation: horsepower = (torque x RPM) / 5252. Since torque and RPM do not increase or decrease at the same rate, the relationship between all three variables is not linear. Torque typically peaks at lower RPMs, while horsepower peaks at higher RPMs in internal combustion engines.
What happens to torque when something rotates faster?
When an object rotates faster, the angular velocity increases while the torque remains constant. This is described by the equation torque = moment of inertia * angular acceleration. Thus, if angular acceleration increases, torque may change to match the new acceleration.
What is a universal joint typically used for?
It is a mechanical connection between rotating shafts which are generally not in parallel, but intersecting. It can allow positive transmission of rotating power at a much larger angle than is permissible with a flexible coupling. And it can transmit torque and motion.
How many Nm do you need to turn a 5kw generator?
power=torque x speed p=txn 5000w= torque x angular speed if the speed of rotation is known, then from above formula we can find the minimum torque required to run the generator.
In a bevel gear is the torque increased decreased or constant?
There are 3 possibilities:-1) If the pinion has less teeth than the wheel - torque is increased.2) If the pinion has more teeth than the wheel - torque is decreased.3) If the pinion has the same number of teeth as the wheel - torque is constant.
What is function of dc motor in lift?
Shunt motor is used. For constant speed ,torque will high when load is increased
What will happen to speed-torque characteristics of an induction motor is the rotor resistance is increased?
If Rotor resistance is increased torque is increased
What is the torque setting for Universal Joint bolts on K2500 Suburban?
Universal joints are always under constant pressure and stress from the movement of the drive shaft and vibrations caused by its rotation. It is important therefore to tighten the bolts securely, applying between 70 to 80 foot pounds of force on the torque wrench.
Is a lathe a constant torque or horsepower?
It's a constant horsepower
What is better constant torque or constant power engines?
mk
What will happen to motor when the torque of the motor is decreased?
flux linkage decreases due to that torque decreases and so speed will decreases
If force is kept constant then the torque becomes double or half?
If force is kept constant and torque is doubled, it means the distance from the point where the force is applied to the axis of rotation has been doubled. If torque is halved, the distance has been halved. Torque is the product of force and distance, so changing the distance changes the torque.
What is torque when angular momentum is constant?
When angular momentum is constant, torque is zero. This means that there is no net external force causing the object to rotate or change its rotational motion. The law of conservation of angular momentum states that if no external torque is acting on a system, the total angular momentum of the system remains constant.
Why is a diesel engine known as a constant torque machine?
ming?
Do pulleys increase torque or speed?
Pulleys can be used to increase torque or speed, depending on how they are configured. When the pulley with a larger diameter is driving a pulley with a smaller diameter, torque is increased while speed is reduced. Conversely, when a small pulley is driving a larger pulley, speed is increased while torque is reduced.
If the torque of the rotational motion be zero then the constant quantity will be?
angular momentum
