What is the unit of torque in robotics?

Torque is a special moment in physics, which is equal to the product of force and moment arm. The international unit is Newton-meter N·m. Torque is a form of force acting on an object. It causes the object to rotate, and its effect is equal to the product of the force and the moment arm.

Torque is a special moment in physics, which is equal to the product of force and moment arm. The international unit is Newton-meter N·m.

Torque is a form of force acting on an object. It causes the object to rotate, and its effect is equal to the product of the force and the moment arm (the distance from the force to the center of rotation).

Conversion of Newton-meter and kilogram-force:

1. 1 Newton*meter (N*m)=0.101972 Kilogram-force*meter (kgf*m)

2. 1 kilogram force*meter (kgf*m)=9.80665 Newton*meter (N*m)

Torque calculation method:

There is a relative torque value at each speed. These values ​​are divided by a length to obtain force data. For example, a 1.6-liter engine can produce a maximum torque of approximately 15.0kg·m.

At this time, if a 185/60R14 size tire is directly connected with a radius of about 41 cm, the propulsive force exerted by the wheel is 15/0.41=36.6kg (in fact, kilogram is not a force) The unit, but the unit of mass, must be multiplied by the acceleration of gravity 9.8m/s² to obtain the standard unit of force (Newton).

Using gears of different sizes to connect and match, the rotation speed can be reduced and the torque can be amplified at the same time. Since the circumferential ratio of the gear is the radius ratio, when power is transmitted from the small gear to the large gear, the rate of reduction in rotational speed and the multiple of torque amplification are exactly equal to the ratio of the number of teeth of the two gears. This ratio is the so-called gear ratio.
