Why is torque speed important?

plots the torque of a motor against the speed the motor is going at. Given that the amount of torque available changes with a change in speed it is important to think about the performance point you need when selecting a motor and controller. …

How does speed affect torque power?

Torque multiplied by rpm returns horsepower. Basically, the faster the crankshaft spins with the same amount of force, the more power an engine will make. A car with more hp than torque will always be quicker since this gives a car acceleration and speed.

What is the relationship between torque and speed in constant type load?

3. What is the relationship between torque and speed in constant type loads? Explanation: Speed hoist is a perfect example of constant type loads in which torque variation is independent of speed. The speed-torque characteristics of this type of load are given by T=K where K is a constant.

Is torque dependent on speed?

The torque injects power and it purely depends on instantaneous velocity.

Why does torque decrease when speed increases?

As the engine is raised above this speed, its torque starts to decrease; due to the increasing friction of the engine’s moving parts. So, even if you rev the engine over & above the peak-torque speed; the torque doesn’t increase any further. Engine torque is multiplied by gears.

What is the relationship between torque and speed Mcq?

The relation between torque and speed are inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity.

Why torque is independent of speed in paper mill drive?

A low speed hoist is an example of a load where the torque is constant and independent of the speed (Fig. 2.3). At low speeds, windage torque is negligible. Therefore, net torque is mainly due to gravity which is constant and independent of speed. Consequently, torque is independent of speed, e.g. paper mill drive.
