If the permanent magnet DC motor is used normally, there is generally no problem, but it is inevitable that there may be some problems in the process of use, such as vibration problems, at this time we need to master the relevant knowledge, so that we also know how to solve the problem. Here's how to solve the vibration problem of permanent magnet DC motor.


First, install spring vibration isolator:


1, the choice of spring vibration isolator style: generally choose self-supporting spring shock absorber, its advantages of simple structure, low cost; The spring is exposed, which is easy to observe the state of the spring at any time. The spring that needs to be replaced is disposed of in advance to avoid excessive damage caused by corrosion of the spring, resulting in sudden settlement of the permanent magnet DC motor causing equipment damage and pipe tearing.


2, the choice of spring: general shock absorber manufacturers choose the spring to meet the following requirements: the diameter of the spring should not be less than 0.8 times the height of its rated load; The spring must have additional travel, and the vortex flowmeter must be equal to at least 50% of the rated static deflection; The horizontal stiffness of the spring is at least stiff steel to ensure the stability of the permanent magnet DC motor shock absorber.


3, the choice of spring shock absorber deflection: the rated deflection of the spring shock absorber (rated compression of the spring) is generally 25MM(self-frequency value of about 3-4 Hz), and this deflection can be the isolation of the vacuum pump at 650 RPM. When the speed is less than 650, it is recommended to use a spring isolator with a deflection below 40.


Second, install rubber vibration isolator: the selection of rubber vibration isolator material is generally neoprene rubber (C.R), generally choose compression rubber shock absorber, for light weight permanent magnet DC motor, can choose shear rubber shock absorber; Compared with the spring shock absorber, the vibration isolation performance of the rubber shock absorber is relatively different.


Installing an elastic base: In order to meet more stringent vibration standards, installing an elastic base with a spring isolator is undoubtedly a good choice.


It can be seen that it is very important to understand the vibration solution of permanent magnet DC motor, because the permanent magnet DC motor plays a very important role in the actual work, if you want to know more, you can go to its official website for further understanding. I hope we introduce these content is helpful to you, but also hope that you can learn useful knowledge.
