Improving the accuracy and speed of fault diagnosis is necessary for a 63mm PMDC motor supplier to have a long lifespan. What are the characteristics of a 63mm PMDC motor supplier when it malfunctions? Below is an introduction to the characteristics of the 63mm pmdc motor supplier fault.

1. Bearing peeling and pitting due to fatigue

2. Severe imbalance, bending, and movement of bearings

3. The gear meshing frequency and its harmonics are the carrier frequency, and the shaft rotation frequency and its harmonics of the gear are the modulation frequency of the meshing frequency modulation. The vibration energy and envelope energy increase to a certain extent. When this phenomenon occurs, it indicates that the 63mm pmdc motor supplier has a tooth profile error fault.

4. An impact type vibration with a large amplitude occurs, with a frequency equal to the rotational frequency of the shaft with broken teeth.

5. During the meshing process, when the gear rotates and the pitting is removed, due to the sudden increase in friction, one or several impact phenomena will occur, and the meshing vibration will be modulated. Its frequency domain is manifested as a series of equidistant frequency clusters in the signal spectrum. When this phenomenon occurs, it indicates that the 63mm pmdc motor supplier has a tooth surface pitting fault.

6. The vibration energy is high, resulting in the phenomenon of box resonance.

7. The frequency of gear meshing and the amplitude of its harmonics increase significantly, and the higher the order, the greater the amplitude increase, resulting in a significant increase in vibration energy. This indicates a fault of uniform gear wear.
