What are the common mechanical failures and solutions for brushless motor motor manual stator slot wedge machine?
The following is a summary of common mechanical failures and solutions for brushless motor manual stator slot wedge machine:
Brushless motor manual stator slot wedge machine common mechanical failures and solutions
First, the common mechanical failure
1, transmission mechanism stagnation or wear
Phenomenon: handle rotation difficulties, gear / belt slippage, noise increase.
Reason: insufficient lubrication, gear wear, belt aging or improper tightening.
Solution:
Clean and add grease (e.g. lithium grease) regularly.
Replace worn gears or aging belt, adjust the belt tightness.
2, pressure mechanism failure
Phenomenon: The slot wedge is inserted insufficiently or too violently, resulting in damage to the stator slot.
Cause: Spring fatigue, air / hydraulic system leakage / oil leakage.
Solution:
Replace the spring that has failed elastically.
Check the seals and repair air/oil leaks.
3. Positioning deviation
Phenomenon: The slot wedge insertion position is deviated, resulting in an untidy stator winding.
Cause: Loose fixture, worn positioning pin, deformed guide rail.
Solution:
Tighten the fixture screws and replace the worn positioning pins.
Correct or replace the deformed guide rail.
4、Deformation or wear of guide parts
Phenomenon: The slot wedge insertion path is skewed, jamming frequently.
Reason: Long-term force leads to deformation of the guide bar / guide rail or surface wear.
Solution:
Use a micrometer to correct the straightness of the guide parts.
Replace the guide parts with high hardness material (e.g. chrome-plated steel) in case of serious wear.
5、Loose fasteners
Phenomenon: The whole equipment shakes when running, affecting the accuracy.
Reason: Screws and nuts are not regularly checked, and vibration causes loosening.
Solution:
Regularly check and tighten the screws of each connection part.
Use thread adhesive or spring washers in key parts to prevent loosening.
Second, preventive maintenance recommendations
1、Daily maintenance:
Clean the equipment after daily use, clear away iron filings and dust.
Lubricate the transmission parts (gears, chains) once a week.
2、Regular calibration:
Check the positioning fixture and guiding accuracy every month, and adjust if necessary.
Quarterly calibration of the pressure mechanism output force is up to standard.
