How do I make a preliminary inspection of a new DC motor ?
First check the appearance of the DC motor. It should be free of scratches, bumps, and coatings falling off.
Then rotate the shaft, it should be able to rotate flexibly without obvious jamming.
Check that the motor of the DC motor is connected securely and is powered on.
The motor of a DC motor should have no friction during the rotation process, the most prominent of which is bearing friction. After the bearings are worn out, abnormal sounds will be emitted, and local overheating and temperature rise will occur.
