The mechanical characteristics of the motor are soft and hard, for example, under the rated voltage, if the load changes, the speed change is small, then we call the mechanical characteristics hard, on the contrary, if the speed changes greatly, it means that the mechanical characteristics are soft; Then here is a simple understanding of the mechanical characteristics of three-phase asynchronous motors with Senli Motor Xiaobian.

       In order to measure a degree of flatness of mechanical characteristics, so there is the concept of mechanical characteristics hardness, which belongs to the ratio of torque change and the speed change caused by it, called mechanical characteristics hardness, which can be divided into three categories, absolute hard characteristics, hard characteristics and soft characteristics.

       Of course, the characteristics of three-phase asynchronous motors have inherent characteristics, artificial characteristics, we will be called natural characteristics, it refers to the rated conditions on the same shaft load speed and torque relationship. Artificial characteristics refer to the mechanical characteristics when the supply voltage or magnetic flux is not rated and the armature circuit has external resistance.

       Mechanical characteristics is a subject that studies the power and motion transmission laws of machines or systems and the best matching of parameters. It is a branch of the discipline of mechanical principles.

       The purpose of the motor to drive the load is to provide a certain torque to the working machine and make it run at a certain speed. Torque and speed are the two basic requirements of production machinery to the motor. It is of great significance to study the mechanical characteristics of the motor to meet the technical requirements of production machinery, make full use of the motor power and design the control and speed regulation system of electric drive reasonably.
