ID HQ SERIES ARMATURE [ID HM920 | ID HM810M | ID HM810S | ID HM810T] DEMOLITION HAMMER SPARE PART [Makita Type] - 29008

This armature (SKU: 29008) is compatible with the ID HM920, ID HM810M, ID HM810S, and ID HM810T demolition hammers from the Ideal Power Tools HQ Series. These are Makita-type machines, meaning the armature follows the same dimensional and electrical specifications as the equivalent Makita OEM part, making it a reliable aftermarket replacement.

This is an aftermarket replacement armature manufactured by Ideal Power Tools to fit Makita-type demolition hammers. It is engineered to OEM-equivalent specifications — including winding gauge, core dimensions, and commutator tolerances — and carries CE (Machine Test) certification, confirming it meets the required safety and performance standards.

Replacing a faulty armature is significantly more economical than purchasing a new demolition hammer. At AED 25, this spare part restores the tool to full working condition — saving hundreds of dirhams compared to a full unit replacement. For professional workshops and contractors managing multiple tools, armature-level repairs are standard practice to extend equipment lifespan and reduce operational costs.

The armature is the rotating component at the heart of the demolition hammer's electric motor. It consists of a magnetic core, copper winding, and commutator. When electrical current passes through the windings, it interacts with the stator's magnetic field to generate rotational force — this rotation is then converted by the hammer's internal mechanism into the high-impact reciprocating action that drives the chisel or bit into concrete, masonry, or stone.

This armature weighs 689 grams, which reflects the use of heavy-gauge copper windings and a solid magnetic core. A higher-weight armature generally indicates more copper content in the windings, which improves electrical conductivity, heat dissipation, and overall motor efficiency — all critical factors for sustained performance in heavy-duty demolition applications.

Each order includes one (1) armature unit supplied in Ideal Power Tools' branded packaging. The armature arrives ready for installation and carries CE (Machine Test) certification, confirming it has been tested to meet applicable machine safety standards. No additional tools or components are included — standard demolition hammer service tools are required for installation.

Common signs of a failing armature include: the tool not starting or starting intermittently, significant loss of power or impact force, excessive sparking at the brush contact area, a burning smell during operation, or visible discolouration or damage to the commutator. If your ID HM920, HM810M, HM810S, or HM810T is exhibiting any of these symptoms, inspecting and replacing the armature is the recommended first step before considering full motor or tool replacement.

This armature is designed for Ideal Power Tools HQ Series machines (Makita-type) — specifically the ID HM920, ID HM810M, ID HM810S, and ID HM810T. While these tools share dimensional similarities with certain Makita models, we recommend verifying the shaft diameter, overall length, and commutator segment count against your specific Makita model's service manual before ordering. For confirmed compatibility with genuine Makita units, please contact our team with your model number.

After installing the replacement armature, run the demolition hammer briefly at no load and check for: smooth motor startup without hesitation, absence of unusual sparking at the brush area, no burning smell, and consistent impact force delivery. It is also advisable to inspect and replace the carbon brushes at the same time, as worn brushes on a new commutator surface can cause premature wear. If issues persist, verify that all internal connections are secure and that the field coil (stator) is also in good condition.
