Product Description
The Eddy Mark IV Series Rotor (Armature), A-1017 is a genuine OEM replacement armature (rotor) for the Eddy Mark IV heavy-duty electric heat gun series. This key motor component features copper commutators that interface with the carbon brushes, enabling smooth, efficient rotation in the brushed DC motor design. It works in conjunction with the field assembly (stator, sold separately as a related part) to deliver the reliable power needed for consistent high-volume airflow and performance.
Key Features:
- Precise OEM compatibility — Direct drop-in replacement for the armature in all Eddy Mark IV Series models (including EP-3ULM, EP-5ULM, EP-6ULM, EP-7ULM, and EP-1100 Plus), restoring original motor specs without modifications.
- Includes nylon washers — Comes pre-equipped with nylon washers for proper alignment, reduced vibration, and extended bearing life during reassembly.
- High-quality construction — Precision-wound armature with durable commutators engineered for heavy-duty, continuous, or intermittent use; supports motor speeds of approximately 7,200–7,500 RPM when paired with fresh brushes and stator.
- Restores peak performance — Addresses common issues like worn commutators causing rough running, excessive noise, reduced speed, sparking, or motor failure over time.
- Easy installation — Designed for technician-level replacement: disassemble the Lexan housing, swap the armature, and reassemble with existing or new brushes—tools required include basic screwdrivers and possibly needle-nose pliers.
Benefits and Ideal Uses: This rotor replacement is essential for maintaining or reviving Eddy Mark IV heat guns, legendary for their rugged G.E. Lexan construction, adjustable airflow/temperature, and long service life in professional environments. Use it to:
- Repair motors showing signs of wear from prolonged use in demanding tasks.
- Achieve quiet, smooth operation and full power output after brush or stator service.
- Extend tool longevity in high-volume applications like heat-shrinking tubing, paint/varnish stripping, plastic forming/bending, adhesive activation, drying coatings, thawing frozen materials, or general industrial heating.
- Support fleet maintenance for automotive, marine, fabrication, upholstery, electronics, HVAC, or orthopedic/appliance repair trades.
The Eddy Mark IV's brushed motor system (stator + armature + carbon brushes) makes this armature a foundational part for reliable, high-RPM fan drive. It's affordably priced as a manufacturer-direct component, offering significant savings over purchasing a new heat gun.
Note: For optimal results, pair with a fresh Brush Kit (2 carbon brushes + springs) and inspect/replace the stator (A-1017 variant or related) if needed during a full motor rebuild. Installation requires electrical safety knowledge—always unplug the tool, discharge capacitors if present, allow full cooling, and follow Eddy service guidelines or related videos (e.g., for similar element swaps). Not interchangeable with other Eddy series like the VT-1100. Prioritize safety with proper PPE and ventilation during repairs.
