Maintenance Methods for the Core of a Gear Motor

The maintenance of the core (iron core) in a gear motor involves several specific methods to ensure its proper functioning and longevity. Below are the steps for core maintenance:

Surface Damage Repair

For surface damage, use a file to remove any protruding burrs. After smoothing the surface, separate the connected silicon steel sheets, clean the surface with a brush dipped in gasoline, and then apply insulation varnish to restore the protective coating.

Tooth Root Burnout Repair

In cases of minor tooth root burnouts caused by grounding faults, break the damaged teeth off, remove any burrs, and fill the area with insulating glue. When chiseling, take care not to damage the windings.

Loose Core Fixation

If the core is loose, additional positioning screws can be added to the housing of the variable-speed gear motor to secure the core. Alternatively, the core can be welded in place to ensure it remains fixed.

Axial Expansion at the Teeth

This issue is typically caused by insufficient pressure from the end rings. If not repaired promptly, it can damage the slot insulation and coils. To fix this, fabricate two steel discs based on the core’s dimensions. Then, use double-ended bolts to clamp the discs at both ends of the core to restore its original shape.

These maintenance methods ensure that the gear motor’s iron core remains in good working condition. Improving efficiency and extending the motor’s lifespan.
