Multiquip 249357060 Armature Assembly 120V - OEM Replacement Part for Concrete Vibrators

The armature assembly is the rotating electromagnetic core inside the motor of Multiquip UM series concrete vibrators, converting electrical energy into mechanical motion to generate the high-frequency vibrations needed for concrete consolidation. This 120V armature assembly is a critical wear component that operates at 12,000-15,500 VPM (200-258 Hz) and draws 3.8 amps at 280 watts during operation.

The UM series vibrators rely on this armature to deliver consistent amplitude and frequency for effective concrete placement. Motor failure symptoms indicating armature replacement needs include reduced vibration intensity, unusual noise, overheating, or complete motor failure. The armature must be properly cooled by immersion in fresh concrete during operation - running the vibrator in air can cause premature armature burnout. When replacing, ensure the power source outlet is compatible with the plug to prevent motor damage and electrocution hazards.
