Wacker Neuson 5100006186 Motor Armature Complete

The Wacker Neuson 5100006186 Motor Armature Complete is a genuine OEM component designed for the IRFU45, IREN45, IRSEN45, IRSE-FU45, and IRflex45 series internal concrete vibrators. As a direct OEM replacement, this armature is built to the exact electrical and mechanical specifications of the original, ensuring the motor delivers the correct speed and vibration output for effective concrete consolidation. Part number 5100006186 covers an extensive range of 45mm-head vibrator configurations including standard, GV, CH, Laser, and flex-head variants across multiple voltage and hose-length options. If your internal vibrator motor has lost power, runs rough, or has stopped turning entirely, this is the core rotating assembly that needs to be addressed.

Key Features

• Exact Electrical Specification: — Wound and balanced to OEM output ratings, maintaining the correct RPM and vibration frequency that 45mm-head IRFU, IREN, and IRflex vibrators require for proper concrete consolidation.
• Genuine Wacker Neuson OEM Part: — Sourced directly through Wacker Neuson's authorized parts supply chain, carrying part number 5100006186 for confident identification and procurement.
• Broad IRFU45 / IREN45 / IRflex45 Coverage: — Fits standard, GV, CH, Laser, UK, US, and flex-head variants across 5-meter, 10-meter, 15-meter, and 18-meter hose configurations in both 115V and 230V/250V versions.
• Complete Drop-In Armature Assembly: — Supplied as a complete assembly, replacing the full rotating core of the motor in a single service operation rather than sourcing individual sub-components.
• Restores Full Motor Output: — A worn or failed armature causes loss of vibration amplitude, overheating, or complete motor failure; replacing with this OEM unit restores the head to full operating performance.

The motor armature is the rotating core of the electric drive motor inside an internal concrete vibrator. It converts electrical energy into rotational force, which the eccentric mechanism then translates into the high-frequency vibration needed to consolidate fresh concrete and eliminate air voids. When an armature wears out or fails — through brush wear, winding damage, or bearing deterioration — the vibrator head loses power, vibrates inconsistently, or stops functioning altogether, directly compromising concrete quality. Replacing the armature complete restores the motor to its original rotational speed and output, bringing the vibrator head back to full working specification.
