- Bosch GSH11E & HQ11E Compatibility: Engineered as a direct-fit replacement for the ID HQ Series, this armature is specifically designed to match the internal dimensions, shaft diameter, and commutator specifications of Bosch-type GSH11E and HQ11E demolition hammers — ensuring a seamless, tool-free installation with no machining or adaptation required.
- 3-Wire Electrical Configuration: The 3-wire winding layout provides a balanced and stable current path through the armature coils, minimising heat build-up during prolonged heavy-duty use. This design reduces the risk of insulation breakdown and extends the operational lifespan of the repaired tool significantly compared to lower-grade alternatives.
- High-Grade Magnetic Core and Precision Commutator: The armature features a laminated magnetic core that reduces eddy current losses, paired with a precision-machined commutator that ensures consistent brush contact. Together, these components deliver smooth, high-torque rotational output — critical for the sustained impact performance demanded by concrete breaking and chiselling applications.
- Energy-to-Mechanical Conversion Efficiency: At the heart of every demolition hammer, the armature is responsible for converting incoming electrical energy into the rotational mechanical force that drives the hammer mechanism. A worn or failed armature directly causes loss of power, overheating, and tool shutdown — making this a critical repair component that restores the tool to its original rated performance.
- CE (Machine Test) Certified — Built to European Safety Standards: This replacement armature carries CE certification under machine testing protocols, confirming it meets the electromagnetic compatibility, insulation resistance, and mechanical integrity requirements set by European safety directives. It ships as a single armature unit (1 piece), ready for immediate installation by a qualified technician.
General Purchase & Comparison Queries
Is this armature a genuine Bosch part or an aftermarket replacement?
This is a high-quality aftermarket replacement armature engineered to the same dimensional and electrical specifications as the original Bosch GSH11E and HQ11E armature. It is CE (Machine Test) certified and designed for direct fitment, offering a cost-effective alternative to OEM pricing without compromising on performance or safety compliance.
Which demolition hammer models is this armature compatible with?
This armature is compatible with Bosch-type GSH11E and HQ11E demolition hammers within the ID HQ Series range. The 3-wire configuration and commutator dimensions are matched to these specific models. If you are unsure whether this part fits your tool, please check your tool's model number and compare it against the listed compatible models before purchasing.
Why should I replace the armature instead of buying a new demolition hammer?
Replacing a worn or burnt armature is significantly more cost-effective than purchasing a new demolition hammer. The armature is one of the most common failure points in heavy-duty power tools due to heat and electrical stress over time. A quality replacement armature restores the tool to its original rated performance, extending the working life of your equipment at a fraction of the cost of a new machine.
Product-Specific and Usage Queries
What does the armature do inside a demolition hammer?
The armature is the rotating core of the electric motor inside your demolition hammer. It consists of a laminated magnetic core, copper windings, and a commutator. When electrical current passes through the windings, it interacts with the stator's magnetic field to generate rotational force. This rotation drives the hammer mechanism that delivers the high-impact blows needed for concrete breaking, chiselling, and demolition work.
What does the 3-wire configuration mean and why does it matter?
The 3-wire configuration refers to the number of electrical connection wires on the armature. This design ensures a balanced current distribution across the winding coils, which reduces localised heat build-up and improves overall motor efficiency. It is the correct specification for the GSH11E and HQ11E models — using an armature with the wrong wire count or winding configuration can result in poor performance or damage to the tool.
How many armature pieces are included in this listing?
This listing includes one (1) armature unit. The package contains the complete armature assembly — magnetic core, windings, and commutator — ready for installation. No additional components are included. If you require brushes, field coils, or other associated parts, these are available separately in our spare parts catalogue.
Problem/Solution-Oriented Queries
My demolition hammer has lost power and is overheating — could the armature be the cause?
Yes — loss of power, excessive heat, burning smell, and intermittent operation are the most common symptoms of a failing armature. Over time, the copper windings can short-circuit or burn out due to sustained high-load use, causing the motor to draw excess current and overheat. Replacing the armature with this CE-certified ID HQ Series replacement will restore normal power output and eliminate overheating caused by winding failure.
My hammer runs but produces sparking and vibration — is this an armature issue?
Excessive sparking at the brush contact area and abnormal vibration are strong indicators of commutator wear or armature winding damage. A worn commutator surface causes uneven brush contact, leading to arcing and vibration during operation. Replacing the armature — which includes a precision-machined commutator — resolves these symptoms and restores smooth, stable motor operation.
Can I install this armature myself or do I need a professional technician?
Armature replacement on a demolition hammer involves disassembling the motor housing, removing the field coil assembly, and carefully extracting the old armature. While experienced DIY users with the correct tools can perform this repair, it is strongly recommended to have the replacement carried out by a qualified power tool technician to ensure correct installation, proper brush seating, and safe reassembly. Incorrect installation can damage the new armature or create an electrical hazard.
