Inertia is a modern word that refers to a physical quantity whose inertia is measured by the mass of a substance, its size corresponds to the mass of a substance. We all know that the match between the load inertia the motor inertia, in addition to affecting the power transmission of the system, it is a very important factor in the many factors that cause the system to be unstable even uncontrollable. Today, permanent magnet motor manufacturers will teach you how to solve the problem of mismatch between load inertia motor inertia.

1. It is possible to increase the inertia on the motor shaft adopt a suitable speed change mechanism to reduce the mismatch between the load inertia the motor inertia to a small extent.

2. Improve the stiffness of the mechanical system.

Of course, in addition to the above methods, this problem can also be solved by the selection of the motor:

1. Choose large inertia motor

In the case that the low inertia motor scheme can be realized, sometimes it is better to use a large inertia motor with the same torque class a flywheel on the rotating shaft, which can provide a reasonable compromise between the higher dynamic performance stability of the servo drive system.

2. Choose low inertia motor

The selection of low inertia motor will help to reduce the total system inertia, so that the system can obtain higher acceleration larger frequency band width; At the same time of increasing acceleration performance, variable speed mechanism can be used to reduce the mismatch between load inertia motor inertia. However, in order to match the inertia of the load with the inertia of the motor, the cost of adopting a better speed ratio scheme is high, sometimes it is necessarily possible to achieve.
