How is fan torque calculated?

How is fan torque calculated?

Example 1. Fan: Size 55 backward inclined airfoil impeller Class II, 835 rpm, 56 bhp 2337 lb-ft2 = WR2 of the impeller 0.75 lb-ft2 = WR2 of the shaft The torque supplied by the motor also varies during starting. A typical motor speed torque curve is shown in Figure 1.

How is motor torque calculated?

1. Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)
2. Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.
3. Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
4. Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

Is it better to have more torque?

Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms. This is also why people talk about “low-end torque” being important for better power at slower speeds.

How do I get more low end torque?

How to Increase Low End Torque?

1. Change the flowing exhausts and intake systems. Replace these components with a new one if you find any damage.
2. Install some high-quality spark plugs.
3. Replace the ignition lead with a better one.
4. Retune the air/fuel ratio (AFR) and the ignition timing maps.

Can a car have too much torque?

You see, more torque does not always make a car faster. Once you exceed the traction capabilities of the tires they go up in smoke and the car doesn’t go anywhere.

What is maximum car torque?

The primary use of torque is to make the car accelerate, and the number usually quoted is the maximum torque of the internal-combustion engine at the crankshaft – and that’s usually higher than the amount at the wheels. But it’s not just about speed, torque is also important when vehicles get heavier and larger.

What is maximum torque in induction motor?

Hence, the developed torque is maximum when the rotor resistance per phase is equal to the rotor reactance per phase under running conditions. By putting the value of sX20 = R2 in equation (1) we get the equation for maximum torque.
