What is the effect of high inertia loads on induction motor?
The alternative rating applied to induction motors, is the maximum load inertia. This is the maximum load inertia that can be started by this motor. A higher inertia would result in to much rotor heating and premature rotor failure.
Which clutch is recommended for applications that require starting high inertia loads?
centrifugal clutch
The centrifugal clutch and the fluid coupling are older technologies often used in high inertia load systems. Both meet a basic design need: they provide soft engagement of loads while allowing for full or nearly full application of horsepower into drive systems.
What is an inertia load?
What is “Load Inertia”? Load inertia, or moment of inertia, is the resistance of any physical object to any change in its speed from the perspective of the rotational axis. For a rotary load, it’s the product of its mass and the square of the perpendicular distance of the mass from the axis.
What is high inertia loads?
In terms of motor starting, a high inertia load is one that requires a relatively lengthy acceleration period before the motor achieves normal operating speed. High inertia loads are found in motor starter applications throughout industry.
What does high inertia mean?
Higher moments of inertia indicate that more force has to be applied in order to cause a rotation whereas lower moments of inertia means that only low forces are necessary. Masses that are further away form the axis of rotation have the greatest moment of inertia.
How much HP can a centrifugal clutch handle?
Clutch Features This centrifugal clutch has a height of 55mm (2.17”) and a diameter of 107mm ( 4.21”). It fits any engine with a 3/4″ crankshaft and a 3/16″ keyway. What is this? Generally speaking, it will support any engine with an output of about 4 to 7 hp.
Is a centrifugal clutch automatic?
A centrifugal clutch is an automatic clutch that uses centrifugal force to operate. The output shaft is disengaged at low rotational speed and engages more as speed increases.
What is high inertia load?
What is a good inertia ratio?
Most servo motor manufacturers recommend that the inertia ratio be kept to 10:1 or less, although there are many applications that operate successfully at much higher ratios. The best inertia ratio for an application comes down to the dynamics of the move and the accuracy required.
What is an example of inertia in football?
An example of Newton’s First Law in football is throwing the ball. When the QB puts forward force on the ball and then lets go, the ball wants to keep moving forward. The more force he puts on the ball the more inertia it will have. And the more mass the football has the more force has to be put on it.
What is inertia give two examples?
If you throw a rock straight up, it will not vary from its direction. Inertia enables ice skaters to glide on the ice in a straight line. If the wind is blowing, a tree’s branches are moving. A piece of ripe fruit that falls from the tree will fall in the direction the wind is moving because of inertia.
Is a higher moment of inertia better?
