The Multiquip 249357060 Armature Assembly 120V is a genuine OEM component designed for UM-Series handheld concrete vibrators. As a direct OEM replacement, this armature is manufactured to the exact electrical and mechanical specifications of the original, ensuring correct voltage rating and proper fit within the motor housing. Sourced directly through Multiquip's authorized parts network, the part is the correct part for restoring full motor performance to your UM-Series vibrator. If your handheld vibrator has lost power, it is running rough, or has stopped operating entirely, a failed armature is a common cause — and this is the part that brings it back.
Key Features
- Correct 120V Electrical Specification — Wound and rated to the original 120V output spec, ensuring safe, stable motor operation without voltage mismatch or overheating risk.
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, with precisely balanced windings and commutator segments that match the motor's designed operating profile.
- Direct Drop-In Replacement — Engineered to seat directly into the UM-Series motor housing using the original mounting configuration, so installation is straightforward for any qualified technician.
- Restores Full Vibration Output — A healthy armature delivers consistent rotational energy to the vibrator head, ensuring proper concrete consolidation. A worn or failed armature causes weak or erratic vibration, leaving voids in the pour.
- UM-Series Fitment — Confirmed fit for Multiquip UM-Series handheld concrete vibrators, making 249357060 the accurate replacement choice for this equipment family.
- Electrical Safety Integrity — As a live electrical component in a 120V power tool used around wet concrete, using the correctly rated OEM armature is essential for safe, code-compliant operation.
The armature is the rotating core of the electric motor inside the UM-Series handheld vibrator. It converts electrical energy into the rotational mechanical force that drives the vibrator head, producing the high-frequency vibration needed to consolidate fresh concrete and eliminate air pockets. When the armature wears out or burns out — often showing symptoms like loss of power, excessive sparking at the brushes, or complete motor failure — vibration output drops off or stops entirely, making the tool unable to perform its job. Replacing the armature with the correct OEM part, rated and wound to the original 120V specification, restores the motor to its intended performance level and keeps the tool operating safely.
