How much weight can a 5v Motor lift?
The maximum torque is given as 1.2 kg*cm (which includes the gearbox-transition), which means having wheels with an radius of 1 cm (or 2cm in diameter) will give you a force that is equivalent to 1.2 kg in weight at nominal voltage, as long as your electronics can provide a current of 300 mA (load current).
What is Torque kg cm?
Torque is a measure of “twisting force”. In your case 3 kg.cm means that a “force” of 3 kg acting at a radius of 1 cm would produce the same amount of torque as your motor. Equally that could be 0.1 kg x 30 cm, or 10 kg x 0.3 cm or FWIW – kg is a unit of mass and Newton the corresponding unit of force.
Does 60 kg cm in motors mean it can lift 60 kg?
It isn’t 60 kg/cm. It’s 60 kg-cm. It means the motor can lift a mass of 60 kg at 1 cm perpendicular distance from its shaft, 30 kg at 2 cm. 60 kg-cm is the torque of the motor.
How much torque does my motor need?
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
What is the formula to calculate torque?
Mathematically, torque can be written as T = F * r * sin(theta), and it has units of Newton-meters. When the sum of all torques acting on an object equals zero, it is in rotational equilibrium.
What’s better torque or kW?
Usually, the more kilowatts an engine produces, the faster a car will accelerate. Torque is best considered as the measurement of power at any given engine speed and the one that gets you moving, whereas power is the measurement of how fast torque is being used.
Which is better torque at low rpm or torque at high rpm?
Running at lower RPMs equates to higher torque and thus lower horsepower, while making higher RPM power outputs less torque and higher top horsepower.
What is a good amount of torque for a car?
The lug nuts that attach the wheels to your car typically need to be tightened to about 100lb. -ft of torque — meaning the operator must apply 100 pounds of force to the end of a foot-long wrench.
What is best RPM to drive?
For the best fuel efficiency, keep your RPMs between 1,500 and 2,000 RPM when driving at a constant speed.
Why does torque drop at high rpm?
At high RPM, torque drops off primarily from intake and exhaust flow restriction. Volumetric Efficiency declines because the engine can’t breathe any faster. Mechanical efficiency also declines at higher RPM, due to increased frictional resistance. This further reduces torque at the output.
What happens to torque when RPM increases?
What happens if you increase torque?
The more torque an engine produces, the greater its ability to perform work. The measurement is the same as work, but slightly different. Since torque is a vector (acting in a certain direction), it’s quantified by the units pound-feet and newton-meters.
Why do lower gears have more torque?
A Gear train is capable of switching a given power between torque and speed. So, while starting from rest, a low gear is used. This essentially means that number of tooth on the drive gear are less than those on the driven gear. Hence, a higher torque is achieved by trading-off the speed of the vehicle.
Do higher gears have less torque?
When in a higher gear, the gear disc size increases and torque decreases and rpm increases. Actually, I have skipped explaining how different gear sizes change the speed but that will be a question of its own.
What gear ratio is better for torque?
In general, a lower final drive ratio will lead to less torque at the wheels but a higher top speed. Meanwhile, a higher ratio will result in the opposite, i.e. more torque at the wheels but a lower top speed. Remember, this is done without any change to the power and torque of the engine.
Does 1st gear have more torque?
There is more torque applied in 1st gear in a particular range of RPM, but as the engine’s torque falls with increasing RPM, there comes a speed in 1st where you get more torque at the wheels when you’re in 2nd.
What gear ratio is better for acceleration?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential.
