The Wacker Neuson Armature is a genuine OEM component designed for AR 36, AR 26, and ARFU 36 series external concrete vibrators. As a direct factory replacement, this armature restores full electrical and mechanical function to your vibrator motor, ensuring the unit delivers consistent output to keep concrete consolidation on schedule. Compatible across a wide range of AR and ARFU model configurations including LBV, CS, Vario, and US variants, this part covers one of the broadest fitment ranges in the external vibrator lineup.
Key Features
- Genuine OEM Winding Integrity — Factory-wound coils maintain correct electrical resistance and output rating for each supported voltage configuration, from 42V up to 400V variants.
- Drop-In Motor Replacement — Machined to OEM shaft and lamination stack dimensions, this armature seats directly into the existing motor housing without reworking the end bells or bearing retainers.
- Broad AR and ARFU Compatibility — Fits AR 36 and AR 26 external vibrators across multiple voltage and frequency configurations, as well as ARFU 36 models including US, GB, and standard European variants.
- Restores Full Vibration Output — A worn or shorted armature causes reduced motor speed, uneven vibration force, or complete motor failure; replacing it returns the unit to rated eccentric force and frequency.
- Electrical Safety Compliance — Genuine OEM construction ensures proper insulation class and winding integrity, which is critical in wet concrete environments where electrical faults present a serious risk.
The armature is the rotating core of an electric motor — it carries the wound coils that interact with the stator's magnetic field to generate torque and spin. In an external concrete vibrator, the armature drives the eccentric weight mechanism that produces the vibration force transmitted through the form or mold. When an armature develops a short circuit, open winding, or physical wear on the commutator surface, the motor loses speed and torque, vibration output drops off, and the unit may overheat or fail to start entirely. Replacing a failed armature with a genuine OEM part restores the motor to its original electrical specification and ensures the vibrator performs at its rated force and frequency.
