Torque, torque and torque are actually the same in the motor. Generally in the same article or the same book, the above three nouns are only used one, and it is rare to see two or more at the same time. Although the three words are used in different situations, in the motor, it refers to the driving "moment" generated by the rotor winding in the motor that can be used to drive the mechanical load. The term "moment" refers to the product of the force and the distance of the fulcrum perpendicular to the direction of action of the force.
For a lever, the product of the force and the distance that the fulcrum is perpendicular to the direction of force action is called the moment. For a rotating object, if the center of the rotating shaft is regarded as a fulcrum, the product of the force on the circumference of the rotating object and the distance between the center of the rotating shaft and the direction of the force is called torque. When a cylindrical object is forced to rotate without being rotated, the object has only elastic deformation due to the torsion force. The torque at this time is called torque. Therefore, strictly speaking, it can only be called "torque" in the running motor. It is not appropriate to use "torque" or "torque". However, it is customary to use these three names for a long time, at least for six or seventy years, so no one deliberately corrects it.
There are two types of torque, torque and torque, namely kilograms·m (kg·m) and Newton meters (N·m). K·m (g·m) is only kilograms·m (kg· m) One thousandth. As the friend on the first floor said, "1kg force = 9.8N". 1 kg·m (kg·m) = 9.8 Newton·meter (N·m).
