With the motor manufacturing industry from time to time to carry out, Permanent Magnet DC Deceleration Motor capacity increases from time to time, its operation caused by the unit volume loss is also generally increased, brought about by the temperature rise more prominent, the motor life and operation Reliability has had a serious impact.
The temperature increases, the permanent magnet current is presented when the winding insulation layer is damaged or the life is shortened, the magnetic density of the permanent magnet is reduced and the demagnetization of the permanent magnet, the temperature of the motor caused by the heat shrinkage, and the change of the electrical parameters caused by the temperature change. Due to various reasons, subject to special operating environment constraints, direct measurement of the temperature of the motor parts will be a certain degree of difficulty. Thus, it is important to calculate the temperature of the motor for its design and optimization.
Temperature problem is the Permanent Magnet DC Deceleration Motor in the process of a problem can not be ignored, therefore, the operator work process not only to control the motor temperature, but also control the maintenance of this knowledge.
We use the permanent magnet DC gear motor, often encountered in the coating showing rust phenomenon, you know that lead to the phenomenon of what causes the phenomenon? Next small tape with everyone to discuss the following bar!
1. Permanent Magnet DC Deceleration Motor in the use of the process, if the plating time is not enough, will make the motor coating rust, which belongs to the process of the problem;
2. Motor storage air circulation is not good, wet or temperature change is relatively large, but also make the motor coating rust;
3. If the sealing of the packaging motor is broken, the motor will be oxidized and the coating will be rusted.
4. Before plating, if not seriously eliminate the dirt on the surface of the motor, will also make the motor coating rust.
The above is caused by Permanent Magnet DC Deceleration Motor coating showing rust of the four reasons, we use the motor more attention to the above matters, you can effectively reduce the rust appeared.
