The Dewalt 5140014-96 Angle Grinder Armature converts electrical energy into rotational motion, driving the grinder's motor during operation. A worn or damaged armature can reduce motor efficiency, cause excessive sparking, or prevent the grinder from running.

\n

This part helps with the following symptoms:

\n

• Grinder motor fails to start.

\n

• Excessive sparking from the motor.

\n

• Burning smell during operation.

\n

• Reduced grinding power.

\n

• Motor overheats quickly.

\n

Motor Will Not Start

\n

Quick Check: Confirm that power reaches the grinder and inspect the armature for visible damage or burnt windings.

\n

Fix Suggestion: Inspect the armature for open or shorted windings and install a compatible replacement if testing confirms a failure.

\n

Prevention Tip: Avoid overloading the grinder to reduce stress on the motor components.

\n

Excessive Sparking

\n

Quick Check: Observe the motor through the ventilation openings for unusual sparking around the commutator.

\n

Fix Suggestion: Examine the commutator for heavy wear and fit a new armature if damage is affecting motor operation.

\n

Prevention Tip: Inspect brushes regularly and replace worn brushes before they damage the armature.

\n

Low Motor Power

\n

Quick Check: Check whether the grinder struggles to maintain normal speed under a light workload.

\n

Fix Suggestion: Verify the condition of the brushes and field assembly, then install a new armature if it is no longer producing proper motor output.

\n

Prevention Tip: Operate the grinder within its recommended load capacity.

\n

Motor Overheating

\n

Quick Check: Monitor whether the motor housing becomes unusually hot during normal use.

\n

Fix Suggestion: Test the motor windings and fit a compatible armature when overheating is linked to internal electrical damage.

\n

Prevention Tip: Keep air vents clean to maintain proper motor cooling.

\n

Customer Experience: A user noticed reduced grinding power and increased motor sparking. Installing the Dewalt 5140014-96 Angle Grinder Armature restored smooth motor operation and consistent performance.
