ARMATURE 2-20 HAMMER 2/20 MS-25
The “Armature 2‑20 Hammer” is a replacement rotor/rotating‑electrical component designed for a 2‑20 series hammer drill or rotary hammer machine. The armature is the core rotating part of the motor, responsible for converting electrical energy into mechanical rotational energy — which then powers the hammering or drilling action.
This part is used when the original armature is worn out or damaged: replacing it restores the tool’s power, efficiency, and smooth operation, so the hammer drill works like new again.
What an Armature Does
- The armature carries the windings/coil through which current flows and interacts with the motor’s magnetic field to produce rotor torque (rotation).
- It rotates inside the motor housing on bearings, driving the gearbox or hammer mechanism of the tool.
- A good armature ensures correct motor speed, smooth rotation, minimal vibration, and efficient power transfer.
- A worn or faulty armature can cause reduced power, overheating, sparking, excessive vibration or complete motor failure.
When / Why to Replace With Armature 2‑20 Hammer
- Motor power loss, weak hammering or drilling performance.
- Excessive sparking, burning smell, or rough noise from the drill — signs of damaged rotor or commutator.
- Vibration or imbalance — possibly worn rotor bearings or damaged winding.
- Regular maintenance or refurbishment of an older hammer‑drill to restore original performance.
Usage / Applications
- Replacement part for compatible 2‑20 MS‑25 / 2‑20 series hammer drills or rotary hammer machines.
- Useful in construction, masonry, concrete drilling or chiselling tools where hammer‑drill motors are used.
- Handy for workshops or tool‑repair shops that service rotary hammers.
- Useful for renovators, contractors or DIY users needing to restore an old/damaged hammer‑drill.
