Understanding the Chicago 47606 Hammer Armature
What Is a Hammer Armature?
The hammer armature is a vital component within the electric motor of your power tool. It functions as the movable part of the motor's electromagnetic system, converting electrical energy into mechanical motion. In tools like rotary hammers, demolition hammers, or impact drills, the armature plays a crucial role in generating the force needed to perform heavy-duty tasks.
Role of the Hammer Armature in Your Tool
- Electricity Conversion: The armature interacts with the field windings to produce electromagnetic forces.
- Impact Generation: In hammer tools, it helps generate the reciprocating or rotary impact force.
- Operational Stability: A healthy armature ensures smooth operation, minimal vibrations, and consistent power delivery.

Signs You Need a Chicago 47606 Hammer Armature Replacement
Identifying the symptoms of a failing or damaged hammer armature can prevent further damage to your tool and increase safety. Common signs include:
- Reduced Power or Performance: The tool struggles to deliver the usual impact force.
- Unusual Noises: Grinding, whining, or irregular sounds during operation.
- Overheating: Excess heat during use indicates electrical or mechanical issues.
- Sparking or Burnt Smell: Visible sparks or a burnt odor can point to electrical faults within the armature.
- Frequent Tripping of Circuit Breaker: The motor draws excessive current, causing trips.
- Vibrations or Jerky Operation: Unsteady movements suggest internal component issues.
If you notice any of these symptoms, it's advisable to inspect the armature and consider replacement.

Step-by-Step Guide to Replacing the Hammer Armature
Preparation and Safety Measures
- Disconnect Power: Unplug the tool from the power source.
- Discharge Capacitors: If applicable, ensure capacitors are discharged to prevent shock.
- Wear Safety Equipment: Use gloves and goggles to protect against sharp edges and debris.
- Work in a Clean Area: Ensure your workspace is well-lit and organized.
Disassembly Process
1. Remove External Casing: Use screwdrivers to detach the outer housing, exposing internal components.
2. Locate the Armature Assembly: Typically, the armature is part of the motor assembly, connected to brushes and the commutator.
3. Disconnect Electrical Connections: Carefully detach wiring leading to the armature, taking note of connections for reassembly.
4. Extract the Old Armature: Unscrew or unclip the armature from its mounting. Use pliers if necessary.
Inspection and Testing
- Visual Inspection: Look for burned windings, broken wires, or corrosion.
- Electrical Testing: Use a multimeter to check for continuity and insulation resistance.
- Cleaning: Remove dust, debris, and corrosion from the motor housing and components.
Installing the New Hammer Armature
1. Position the New Armature: Align it properly with the motor shafts and mounts.
2. Reconnect Electrical Wires: Attach wiring securely, ensuring correct connections.
3. Apply Lubricants: Use appropriate electrical grease on connections to prevent corrosion.
4. Secure the Assembly: Tighten screws and clips to hold the armature firmly in place.
Reassembly and Testing
- Replace the external casing, ensuring all screws are tightened.
- Reconnect the power source.
- Test the tool in a controlled environment, observing operation for smoothness, noise, and impact performance.
