380V ZDN50 50mm High-Frequency Motor-in-Head Concrete Vibrator

3,000W Rated Output for Professional Three-Phase Jobsites

The ONNEW ZDN50/380V is a high-frequency internal concrete vibrator designed for contractors who need strong, stable compaction from a three-phase power supply. Its 50mm motor-in-head direct-drive system delivers 3,000W of rated output power, 12,000 vpm, a 2.16mm amplitude and 7,500N of centrifugal force for foundations, walls, columns and infrastructure concrete work.

Why the 380V ZDN50 Stands Out

• 3,000W Rated Output: The integrated motor-in-head system delivers 3,000W of rated output power for fast, consistent consolidation in demanding structural and civil construction.
• Stable Three-Phase Operation: Designed for a rated 380V supply and guaranteed to operate across AC 320–450V, 50/60Hz, helping the vibrator handle common jobsite voltage fluctuations.
• Motor-in-Head Direct Drive: The permanent-magnet motor and eccentric mechanism are built into the vibrating head, eliminating the traditional flexible drive shaft and maintaining consistent performance with different hose lengths.
• Immersion-Ready Frequency Converter: Not only the vibrator head but also the frequency converter inside its heat-dissipating protective housing is designed for powered immersion. The converter can be dragged around the jobsite and immersed in concrete slurry or muddy water together with the complete machine, without a routine operating-depth or runtime limit.
• Wireless Start/Stop Control: Two wireless remote controllers are supplied as standard for convenient single-operator control.
• Configurable Working Reach: A 6m rubber hose and 15m power cable are standard. Hose lengths from 1m to 50m and custom cable lengths are available for different project layouts.

The complete machine is supplied as an integrated assembly: vibrator head, rubber hose, frequency converter, power cable and localized industrial male plug. The standard 380V connection is a 4-pin 3P+E industrial plug; other correctly matched local plug formats can be configured on request.

Power-connection note: The industrial male plug must be correctly wired and grounded, then paired with a compatible jobsite female socket or distribution-board outlet.

Frequently Asked Questions

What power supply does the 380V ZDN50 require?

It uses three-phase power with L1, L2, L3 and protective earth, without a neutral conductor. Rated input is AC 380V, and the guaranteed operating range is AC 320–450V at 50/60Hz.

What is included in the complete machine?

The standard supply includes the vibrator head, 6m rubber hose, frequency converter, 15m power cable, localized industrial male plug and two wireless remote controllers. The jobsite female socket is not included.

Can the hose and cable lengths be customized?

Yes. Rubber hose lengths can be customized from 1m to 50m. Custom power-cable lengths are also available on request.

Can the frequency converter be dragged or immersed during operation?

Yes. Unlike conventional vibrators where only the head enters the concrete, the ONNEW frequency converter is protected by a robust heat-dissipating housing and is designed to remain powered while immersed. The converter and complete machine can be dragged around the jobsite and submerged in muddy water or concrete slurry as work progresses, without a routine operating-depth or runtime limit. The external power connection must always be correctly wired, grounded and paired with a compatible industrial female socket.

Can ONNEW provide a plug for my market?

Yes. The standard 380V plug is a 4-pin 3P+E industrial male plug. Other compatible local industrial plug formats can be configured according to the destination power system and connection requirements.

1. Professional Three-Phase Compaction Performance

• 3,000W rated output: The motor-in-head system delivers 3,000W of rated output power together with 12,000 vpm frequency and a 2.16mm amplitude.
• Powerful consolidation: 7,500N of centrifugal force helps release trapped air and consolidate concrete efficiently around formwork and reinforcement.
• Versatile 50mm head: A practical diameter for foundations, walls, columns, slabs, bridge components and other reinforced concrete structures.

2. Direct-Drive Motor-in-Head Technology

• No traditional flexible drive shaft: The permanent-magnet motor and eccentric mechanism are integrated into the vibrator head, reducing the transmission losses and wear points associated with conventional external-motor shaft vibrators.
• Consistent performance at different reaches: Because the rubber hose does not transmit mechanical rotation, the vibrator can maintain stable working performance across customized hose lengths from 1m to 50m.
• Simpler jobsite handling: The integrated design eliminates the need to carry a separate external drive motor beside the operator.

3. Built for Real Jobsite Power Conditions

• Wide operating range: Guaranteed for AC 320–450V input around a rated 380V supply.
• 50/60Hz compatibility: Suitable for common industrial power systems in international markets.
• Localized connection: Standard 4-pin 3P+E industrial male plug, with other correctly wired and compatible formats available for destination-market requirements.

4. Immersion-Ready Converter, Remote Control and Custom Reach

• Protected frequency converter: The converter sits inside a robust heat-dissipating housing designed for powered immersion. It can be dragged around the jobsite and submerged together with the complete machine as work progresses.
• No routine depth or runtime limit: The complete powered system is designed for continuous immersion in concrete slurry or muddy water.
• Dual wireless controllers: Two remotes are standard, allowing convenient start/stop control without returning to the converter.
• Project-specific reach: Standard 6m hose and 15m cable, with 1–50m hose options and custom cable lengths available on request.

Logistics & Packaging

• The vibrator head, hose, frequency converter, cable, industrial plug and remote controllers are secured as one complete system for shipment.
• Export packaging is selected according to order quantity, transport method and destination requirements. Reinforced protection and moisture-resistant packing can be provided for long-distance transport.
• Customized hose and cable configurations are checked and clearly identified before dispatch.

Storage & Care

• Rinse concrete residue from the vibrator head and hose after use, then wipe and dry the external surfaces before storage.
• Store the machine in a clean, dry and well-ventilated area. Protect the converter, cable and industrial plug from impact, crushing and improper bending.
• Coil the hose and cable without sharp bends. Inspect the power connection, grounding conductor and external seals before the next use.
