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.
