Torque, moment, and twisting force are often used interchangeably in the context of motors. However, in technical literature, these terms are usually used separately within the same article or book. Although they may appear in different contexts, they all refer to the rotational force generated by the rotor windings that drives mechanical loads. The concept of "moment" comes from physics, where it is defined as the product of a force and the perpendicular distance from the fulcrum to the line of action of the force.
For a lever system, the moment is calculated as the product of the applied force and the perpendicular distance from the pivot point. In a rotating object, if we consider the center of the rotating shaft as the fulcrum, the torque is the product of the force acting on the edge of the object and the distance from the center to the direction of the force. When a cylindrical object is subjected to a twisting force without actually rotating, it undergoes elastic deformation due to torsion. At this stage, the force is referred to as torque. Therefore, strictly speaking, in a running motor, the correct term should be "torque," not "moment" or "twisting force." However, over time, people have become accustomed to using all three terms, and few bother to correct them.
There are two common units for torque: kilogram-meter (kg·m) and Newton-meter (N·m). One gram-meter (g·m) is equal to one thousandth of a kilogram-meter. As mentioned earlier, 1 kilogram-force equals 9.8 Newtons, so 1 kg·m is equivalent to 9.8 N·m. Understanding the difference between these units is essential when working with motors, especially in engineering and industrial applications where precision matters.
In summary, while "torque," "moment," and "twisting force" are often used interchangeably, each has its own specific definition and context. It's important to use the correct terminology depending on the situation, especially in technical documentation and design specifications. Familiarizing yourself with the distinctions can help avoid confusion and improve accuracy in your work.
