Key 1: Whether the speed of the motor is normal, whether there is speed jitter and stalled rotation (you can check it with a tachometer).
The key is whether the anchor bolts of the motor are loose, whether the root is defective, and whether there are debris around.
The key is whether the housing and coupling of the motor are defective, and whether the connecting screws of the coupling are loose. Whether there are debris or stains on the motor body, whether the ventilation groove is blocked, etc.
Fourth, the air-cooled motor should pay attention to whether the air pipeline is dredged, whether the connection parts are tight, whether the gate orientation on the pipeline is correct, and whether the ventilation of natural ventilation is outstanding. The water-cooled motor should pay attention to whether the cooling water pipeline is dredged, whether there is cooling water leakage, and whether the cooling water temperature and flow rate are normal.
Keep an eye on the key
Key 1: Synchronous motors, winding motors, etc. should also check whether the touch condition of the brushes and collector rings is outstanding, whether there are commutation sparks, and whether the color and shape of the sparks are abnormal.
The key is whether the excitation system of the synchronous motor is normal.
The key is whether the connection of the motor wiring and grounding wire is loose.
Particularly critical
The key is whether the current of the running motor exceeds the allowable value, whether it corresponds to the actual load, whether there is a sudden change, whether the voltage is within the allowable scale, and whether there is a lack of phase.
The key is whether the temperature of each part of the motor exceeds the allowable value.
The key is whether the bearing is overheated, whether the lubricating grease is sufficient, whether the oil level of the oil level indicator is normal, and whether the oil ring is sensitive to rolling.
Fourth, whether the motor is smoking, whether the winding is discolored and other overheating.

Introduction to the principle of temperature controller - Autonix
The temperature controller is an electrical switchgear that controls the temperature of an air-conditioned room. The temperature scale in the air-conditioned room controlled by the temperature controller is generally 18°C--28°C. The temperature controller commonly used in window air conditioners uses the principle of pressure effect to promote the opening and closing of contacts. Its structure consists of bellows ...

Gas Sensor Failure Analysis – Ottonix
A gas sensor is a converter that converts the volume fraction of a gas into an electrical signal. We will inevitably encounter some problems when using gas sensors, and we have analyzed them as follows:
1. How long does it take for the gas sensor to be used and then calibrated again: the initial calibration ...

Factors that contribute to sensor errors – Ortonix
The first is the offset error: since the high-frequency pressure sensor maintains a stable straight offset over the entire pressure range, the change in converter diffusion and laser adjustment correction will cause the offset error.
The second is the sensitivity error: ...
