Gründe und Lösungen für das Nichtstarten von bürstenlosen Motoren

1. Low Power Supply Voltage or Excessive Voltage Drop during Startup:

Wenn die Versorgungsspannung zu niedrig ist, ermitteln Sie die Grundursache.

Wenn während des Startvorgangs ein übermäßiger Spannungsabfall auftritt, sollten Sie die Startspannung erhöhen. Bei Systemen mit Spartransformator-Startvorrichtungen kann die Startspannung durch Anpassen der Stufenposition erhöht werden.

2. Stator Winding Short Circuit or Ground Fault:

Use a megohmmeter to check for short circuits or ground faults in the stator windings.

3. Open Circuits in Stator or Rotor Windings:

Check for open circuits in both the stator and rotor windings. Ensure that the winding coils, brushes, and slip rings have proper contact.

4.Friction Between Stator and Rotor:

Investigate if there is excessive friction between the stator and rotor of the brushless motor.

5.Incorrect Stator Winding Connection:

Verify the correct connection of the stator windings. Ensure that the winding configuration is accurately set up, avoiding errors like connecting a delta winding as a star winding or reversing the start and end points.

6.Excessive Load on the Brushless Motor:

Reduce the load on the motor if it is operating under heavy loads.

7.Bearing Damage or Seizure:

Inspect the bearings for damage or seizing and replace them if necessary.

8. Overly Taut Belt Causing Increased Friction:

Adjust the tension of the belt to prevent excessive friction. A belt that is too tight can lead to increased friction and difficulty in motor startup.

9.Mechanical Faults in Connected Equipment:

Check if the connected machinery has mechanical issues, such as being rigid or jammed, preventing smooth rotation.

10.Incorrect or Faulty Wiring in the Starting Equipment:

Inspect the wiring of the starting equipment for errors or faults. Correct and troubleshoot any issues.
