Restore Full Power — Built to Perform Under Demolition Demands

Genuine replacement armature engineered for the Hitachi ID PH65HC and ID PH65SC demolition hammers, this ID HQ Series Armature (28762) restores full power and performance to your machine. Designed with a precision-wound magnetic core and commutator, it converts electrical energy into reliable mechanical output, keeping your tool running at peak efficiency on the toughest jobsites.

Key Features Perfect For
  • Hitachi-Type Compatibility — fits ID PH65HC & ID PH65SC models
  • Precision-Wound Coil — ensures consistent torque and power transfer
  • Durable Commutator — resists wear for extended service life
  • High-Grade Magnetic Core — optimised for demolition-class performance
  • CE Certified — meets European machine safety standards
  • Repairing a burnt-out or failed armature in demolition hammers
  • Workshop and field servicing of Hitachi-type power tools
  • Restoring full motor output after heavy-duty use
  • Preventive maintenance for high-frequency jobsite tools
  • Direct-fit replacement for Hitachi ID PH65HC and ID PH65SC: This armature is engineered specifically to the dimensional and electrical specifications of these two demolition hammer models, ensuring a drop-in fit with no modification required — saving workshop time and reducing the risk of installation errors.
  • Precision-wound copper coil for maximum energy transfer: The winding is manufactured to tight tolerances, minimising resistance losses and ensuring that electrical energy from the motor is efficiently converted into the rotational mechanical force needed to drive demolition-class chiselling and breaking work.
  • Hardened commutator for long service intervals: The commutator segments are machined from high-conductivity copper alloy and treated to resist the arcing and heat generated during sustained heavy-duty operation, extending the interval between replacements and reducing total cost of ownership.
  • High-permeability laminated magnetic core: The core is constructed from stacked silicon-steel laminations that reduce eddy current losses, maintain magnetic efficiency at high RPM, and prevent premature overheating — critical for tools operating continuously in concrete breaking and chipping applications.
  • CE Machine Test certified for safety and compliance: This armature carries CE certification, confirming it has been tested to European machinery directive standards. It is supplied as a single unit (1 piece) and is suitable for use by professional repair technicians and tool service centres operating in regulated markets.

This armature is supplied as 1 piece and is the only component included in the package — no additional hardware or brushes are bundled. It carries CE (Machine Test) certification, confirming compliance with European machinery safety directives and making it suitable for use in regulated workshop and professional service environments.

General Purchase & Comparison Queries

Is this armature compatible with my Hitachi demolition hammer?

This armature is specifically designed for Hitachi-type demolition hammers, with confirmed compatibility for the ID PH65HC and ID PH65SC models. If your tool is one of these models, this is a direct-fit replacement. If you are unsure, cross-reference your tool's model number or contact us with your serial number before purchasing.

How does this compare to an OEM Hitachi armature?

This ID HQ Series armature (Part No. 28762) is engineered to match the original specifications of the Hitachi armature it replaces — including winding resistance, commutator dimensions, and core geometry. It carries CE Machine Test certification, which confirms it meets the same safety and performance standards required of machinery components in regulated markets. It offers a cost-effective alternative without compromising on fit or function.

How many pieces are included and what is in the package?

The package contains one (1) armature unit. No additional components such as brushes, bearings, or hardware are included. If your repair requires additional parts, these should be sourced separately to ensure a complete and reliable service.

Product-Specific and Usage Queries

What does an armature do in a demolition hammer?

The armature is the rotating core of the electric motor inside your demolition hammer. It consists of a laminated magnetic core, precision-wound copper coils, and a commutator. When electrical current passes through the windings, it interacts with the stator's magnetic field to generate rotation, which is then converted into the reciprocating hammering action. A faulty armature results in loss of power, overheating, or complete tool failure.

Can I install this armature myself or do I need a technician?

Armature replacement requires disassembly of the motor housing and a working knowledge of power tool servicing. While experienced DIY users with the right tools can perform the replacement, it is generally recommended to have the work carried out by a qualified power tool repair technician to ensure correct installation, proper brush seating, and safe reassembly. Incorrect installation can damage the new armature or other motor components.

What are the signs that my armature needs replacing?

Common indicators of a failed or failing armature include: the tool not starting or starting intermittently, significant loss of power during operation, excessive sparking visible at the brush area, a burning smell during use, or the motor running but the hammer mechanism not engaging. If you observe any of these symptoms, the armature should be inspected and tested before further use.

Problem/Solution-Oriented Queries

My demolition hammer has lost power — will replacing the armature fix it?

Power loss in a demolition hammer is frequently caused by a worn or damaged armature, particularly after extended heavy-duty use. However, power loss can also result from worn carbon brushes, a damaged stator, or mechanical issues in the gearbox. It is advisable to test the armature with a multimeter for open circuits or shorts before replacement. If the armature tests faulty, replacing it with this ID HQ Series unit (28762) should restore full motor output.

The tool is sparking excessively — is the armature the cause?

Excessive sparking at the brush contact points is one of the most common signs of a damaged commutator or shorted armature winding. Over time, the commutator surface can become grooved, burnt, or uneven, causing the brushes to arc heavily. If cleaning the commutator does not resolve the issue, replacing the armature is the correct course of action. This replacement unit features a precision-machined commutator designed to provide clean, consistent brush contact from the first use.

I replaced the brushes but the tool still doesn't work — what next?

If fitting new carbon brushes did not restore tool function, the armature itself is the most likely next point of failure. Brushes and armatures wear together, and a heavily worn commutator can destroy new brushes quickly or prevent proper electrical contact. Inspect the commutator surface for deep grooves, burnt segments, or discolouration. If damage is present, replacing the armature with this CE-certified ID HQ Series unit is the recommended repair step before investigating the stator or switch.
