The Wacker Neuson Armature is a genuine OEM component designed for the AR 75 series external concrete vibrators, covering a wide range of voltage and rpm configurations including 230V, 400V, 440V, 460V, and 550V variants across both 3,000 and 3,600 rpm models. As a direct factory replacement, this armature restores full electrical and mechanical performance to the vibrator motor. Verified compatible models include the AR 75/9/042, AR 75/9/250, AR 75/3/230 v, AR 75/3,6/460 US, AR 75/3/200/400, AR 75/3,6/318/550, AR 75/3/400, AR 75/3,6/230/400, AR 75/3,6/220/440, AR 75/3/240/415, AR 75/3,6/440, and AR 75/10,8/046. Always confirm your model number before ordering.
Key Features
- Genuine OEM Winding Spec — Wound to the original voltage and frequency ratings for your specific AR 75 variant, ensuring correct motor output and vibration force.
- Drop-In Motor Replacement — Machined to OEM shaft and lamination stack dimensions, allowing direct installation into the existing AR 75 motor housing without rework.
- Broad AR 75 Series Coverage — A single part number spans multiple AR 75 configurations across 3,000 and 3,600 rpm ratings and voltage ranges from 200V through 550V.
- Restores Full Vibration Output — A worn or shorted armature causes erratic or lost vibration force; replacing with this OEM unit brings the motor back to its rated eccentric output for consistent concrete consolidation.
- Electrical Safety Compliance — Genuine OEM construction maintains correct insulation class and winding integrity, critical for safe operation on AC-powered external vibrators used on active concrete pours.
The armature is the rotating core of the external vibrator's electric motor — it carries the wound coils that interact with the stator's magnetic field to generate rotational force, which in turn drives the eccentric weight that produces vibration. When the armature windings degrade through heat, moisture ingress, or mechanical wear, the motor loses torque, draws excessive current, or fails to run altogether, interrupting concrete consolidation mid-pour. Replacing a failed armature with a correctly specified OEM unit restores the motor to its original power rating and protects downstream components such as the bearings and stator from the stress caused by an out-of-balance or under-powered rotor.
