Treadmill Motor Repair

Precor, Pacific Scientific, Treadmill Motor Rebuild Includes the Following:

Motor disassembly

Armature testing:  test for shorted windings by a bar to bar electrical resistance ohm test.  Test for insulation breakdown by 1,000 volt hi-pot, and a 500 volt megger test.  Check shaft for straightness.

If windings pass the above tests, the armatures’ commutator is turned, undercut and polished to return the armature to its original condition, within .002” out of round.  The reconditioned armature is checked for proper balance and rebalanced if needed.   If the armature windings do not pass the tests above, you will be notified if rewinding is needed as this would be an extra charge.

Magnets are checked for magnetism and chips or cracks are repaired.

Brush holders are tested for insulation leakage by 1,000 volt hi-pot and 500 volt megger tests.
