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.
This brief overview covers the reasons why a brushless motor may fail to start and suggests corresponding solutions. If the issues persist or are challenging to resolve, feel free to contact Faradyi-Motoren for comprehensive technical support.
