What is constant torque and variable torque?
Constant torque is found in applications such as cranes, mills, conveyor belts, or others. Your torque requirement is constant, regardless of whether the speed is up or down. While the variable torque is found in all kinds of centrifugal loads such as pumps, fans or others.
What is variable torque?
Variable torque is described as the ability of a motor to direct power in a limited way when needed. The motor senses a load and directs more power to help move that load.
What is the quadratic pair?
2. Quadratic torque Quadratic torque is the most common type of load. Typical applications are centrifugal fans and pumps. Torque is quadratically proportional to speed, and power is quadratically proportional to speed.
What is a pair in electrical machines?
The torque is a value that is equivalent to the force exerted by the rotating element times the distance of the lever arm on which this force acts. This torque is expressed in mKg when the force is in kilos and the distance is in meters.

What is par?
Torque is a parameter that measures the power required for the crankshaft to rotate a certain number of turns. That is, the force exerted by the explosion on the piston multiplied by its surface and the number of cylinders.
What is torque and how is it calculated?
As can be seen from its definition, in a combustion engine, torque is a variable that depends on the power generated in the cylinder chambers and the number of revolutions at which the engine is turning at that particular moment, so it could be calculated its value from the formula P = T · ω where P is …
How to calculate starting torque?
The acceleration time of the motor (fan) with nominal torque can be calculated by the formula: The starting time is calculated by dividing the speed range into five sectors. In each sector (198.2 rpm) it is assumed that the torque is constant.
What is the torque of a car?
Motor torque, also known as torque, is a physical magnitude that measures the moment of force that must be applied to a shaft that rotates on itself at a certain speed. Or what is the same, the tendency of a force to rotate an object around an axis, support point, or pivot.
What is the load torque?
A linear load torque is one that increases proportionally with speed. This behavior can be found in viscous friction calenders (or rolls) and paper processing machines. Starting resisting torque is minimal and power increases quadratically with speed.
What is better a high or low torque?
Cars with high-torque engines tend to accelerate more slowly from the start, but quicker from low revs into a high gear. In contrast, cars with low-torque engines tend to accelerate faster from the start, but slower from low revs in a high gear.
The more torque the better?
The higher the torque of an engine and the wider the rev range at which it delivers it, the more oomph the car has, so on a practical level, you could say drivers are more interested in torque than speed. power.
What is torque and horsepower?
The engine torque is the magnitude that mainly determines the acceleration and recovery of the car, while the power rather defines the maximum speed that it is capable of reaching.
What is starting torque?
Starting torque: It is the torque that the motor will develop to break its initial conditions of inertia and start operating.
What is the maximum torque in a car?
The maximum torque is measured in Nm (Newton meters) and represents the force that the engine achieves in a specific rotational speed.
What is the difference between torque and torque?
Also known as torque, it is expressed in Newton meters (Nm) and is defined as the force that must be applied to a shaft that rotates on itself at a certain speed.
What is torque and why is it important in motors?
Torque is the moment of force exerted by a motor on the power transmission shaft or, put another way, the tendency of a force to rotate an object around an axis, fulcrum, or pivot.
What is more important horsepower or torque?
Torque and power are two physical quantities that are related and both have their importance in performance. It all depends on what our needs are. From Autocasión they detail that, in the case of trucks, for example, it is clearly important that the engine torque is as high as possible.
How is the torque of an electric motor calculated?
Multiply the horsepower by 5,252 using a calculator. Using the example figure, multiply 0.6434316 by 5,252 to get 3,379.3027. Divide the result by the engine’s rated rpm number to get the torque in foot-pounds.
How is torque measured?
The torque or motor torque is measured, according to the International System of Units, in Newton meter (N m), although it can also appear inversely, Newton meter (m N).
How is the power output of a motor calculated?
Use this formula to estimate motor horsepower: Horsepower (HP) = Voltage x Amperage x %EF (Motor Efficiency) x Power Factor x 1.73/746.
What is the torque of a motorcycle?
The engine torque is the way to measure the effort made by the gases resulting from combustion, and that through the piston and the connecting rod rotate the crankshaft. Therefore, the greater the cylinder capacity and with it the size of the combustion chamber, the stronger the explosion and the greater the thrust of the gases.
What is torque of 300 Nm?
These acronyms correspond to the units of measurement of motor torque, a physical magnitude that measures the moment of force that has to be applied to a shaft that rotates on itself at a certain speed, these units are the newton meter.
