Standard Type AC Three Phase 8 Poles Vibration Motor

Product Overview

Low-Speed High-Amplitude Vibration Solution for Heavy Material Handling

The Standard Type AC Three-Phase 8-Pole Vibration Motor is an industrial vibration source designed for applications requiring low-frequency and high-amplitude vibration.

The vibration motors create controlled centrifugal force through adjustable eccentric weights installed on both ends of the rotor shaft. The generated exciting force is transmitted to the connected equipment, producing continuous vibration for material movement, screening, compacting, and discharge processes.

The MVE Series 8-Pole Vibration Motor normally operates at:

• 750RPM at 50Hz
• 900RPM at 60Hz

Compared with 22-pole, 4-pole, and 66-polevibration motors, the 8 8-poleesign provides lower vibration frequency with higher amplitude, making it suitable for applications requiring gentle but powerful vibration.

As a professional China vibration motor manufacturer, Putian provides industrial vibration solutions for equipment manufacturers, engineering companies, and distributors worldwide.

What Is an 8 P8-Polebration Motor?

An 8 po8-poleration motor is a specialized motor that converts electrical energy into mechanical vibration.

It is mainly used as a vibration source installed on:

• Vibratingscreens
• Feeders
• Conveyors
• Silodischarge systems
• Concreteequipment
• Material processing lines

The motor does not directly move materials. Instead, it generates vibration force, allowing the connected machine to perform:

• Materialconveying
• Screening
• Compacting
• Separation
• Dischargeassistance

Working Principle

The vibration force is generated by adjustable eccentric blocks mounted on both ends of the rotor shaft.

By changing the position angle of the eccentric blocks, users can adjust vibration intensity according to actual equipment requirements.

Main advantages:

• Adjustable centrifugal force
• Flexible vibration control
• Suitable for different machine designs
• Easy integration into existing equipment

Different installation methods can create different vibration movements. Single motor installation: Circular or elliptical vibration. Two motors installed in opposite rotation. Linear vibration movement

Silo and Hopper Discharge Systems

Bulk materials may stop flowing because of:

• Compression
• Moisture
• Materialbridging

Applications:

• Cementsilos
• Mining material storage
• Grain storage systems
• Powdercontainers
• Chemical storage equipment

The vibration motor helps improve discharge efficiency and reduce material blockage.

Core Features

How to Select the Right Vibration Motor

1. Select According to Vibration Frequency

General comparison:

2. Match Centrifugal Force

The vibration force should match:

• Equipmentweight
• Materialload
• Requiredamplitude

General guideline:

The total centrifugal force is normally selected around 2-3 times the vibrating equipment weight.

Professional equipment manufacturers should verify:

• Vibrationangle
• Amplitude
• Installationposition
