Torque, moment, and turning force are often used interchangeably in motor discussions. However, in technical literature, these terms are typically used individually within the same context. While they may appear in different situations, they all refer to the rotational force generated by the rotor winding that drives a mechanical load. In physics, "moment" is defined as the product of a force and the perpendicular distance from the pivot point to the line of action of the force.
For a lever system, the moment is calculated by multiplying the applied force with the perpendicular distance from the fulcrum. When it comes to rotating objects, if we consider the center of the rotating shaft as the fulcrum, the torque is the product of the force acting on the object’s circumference and the distance from the center of rotation to the point where the force is applied. If a cylindrical object is subjected to a twisting force without actually rotating, it will only experience elastic deformation. This is referred to as torsional stress, and the corresponding value is called torque.
Therefore, strictly speaking, when referring to a running motor, the correct term should be "torque." However, due to long-standing usage, people often use "moment" or "turning force" interchangeably. This has become a common practice over decades, and most people don’t feel the need to correct it. The terminology might vary depending on the region or industry, but the core concept remains the same.
There are two common units for measuring 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 kg-force equals approximately 9.8 newtons. Therefore, 1 kg·m is equivalent to 9.8 N·m. Understanding the relationship between these units is essential when working with motors, especially in engineering and industrial applications.
Whether you're designing a motor, selecting components, or analyzing performance, knowing the difference between torque, moment, and turning force can help you make more accurate decisions. It also ensures clarity when communicating with engineers, technicians, or clients who may use these terms differently based on their background and experience.
