Causes Of Unstable Speed Of DC Motor Core

During the operation of a DC motor, the core occasionally experiences unstable speed. What are the causes of unstable core speed? The following is a brief discussion of the causes and remedies for unstable speed of DC motor cores.
1. Unstable supply voltage or inaccurate control system settings will cause the motor speed to fluctuate, sometimes going fast and sometimes going slow. This will seriously cause the motor to vibrate, which is very dangerous. Testing for fluctuations in power supply voltage is the first step in determining if a power supply failure is the cause of the problem. To ensure proper motor operation, the motor settings must be adjusted.

2. Internal problems with the DC motor, such as off-center brush orientation, series windings, and opposite direction commutation pole windings, can cause changes in motor load and fluctuations in engine speed. Checking and correcting the centerline alignment of the brushes and making sure the windings are oriented correctly is the solution. To troubleshoot more effectively, also see if there is a large change in current.
