Standard Type AC Three Phase 4 Poles Vibration Motor

The Standard Type AC Three-Phase 4-Pole Vibration Motor is an industrial vibration source designed for machines and vibrating equipment that require stable, controlled vibration. Unlike ordinary electric motors that only provide rotary power, this vibration motor uses adjustable eccentric blocks installed on both ends of the rotor shaft to generate centrifugal force and convert rotation into mechanical vibration.

As a professional China vibrator manufacturer and China vibrator factory, Putian provides MVE series vibration motors for global equipment manufacturers, engineering companies, distributors, and industrial users. The four-pole design operates at approximately 1500 RPM at 50Hz and 1800 RPM at 60Hz, providing smoother vibration performance compared with high-speed 2-pole vibration motors.

The Standard Type AC Three-Phase 4-Pole Vibration Motor is widely used for screening, conveying, compacting, feeding, and material discharge applications. With adjustable vibration force, strong mechanical structure, IP66 protection, and continuous-duty capability, it is suitable for demanding industrial environments.

Working Principle and Structural Design

The MVE series 44-polevibration motor generates vibration through adjustable eccentric blocks.

The main structure includes:

• Sidecover
• Adjustable eccentric locks
• Flange
• High-qualitybearing
• Shaft
• Rotor
• CopperCoil
• Motorframe

During operation, the rotor shaft rotates at high speed, driving the eccentric blocks to generate centrifugal force. This exciting force is transmitted through the motor housing to the vibrating equipment.

By adjusting the angle between the fixed and adjustable eccentric blocks, users can achieve adjustment of vibration force according to different application requirements.

The motor can create different vibration trajectories depending on installation methods:

• Single vibration motor installation: Generates circular or > elliptical vibration movement
• Two motors installed with opposite rotation directions: > Generates linear vibration movement
• Different speed combinations: Can create composite vibration > patterns for special equipment requirements

This flexibility allows the same vibration motor series to support different industrial applications.

Industrial Applications

The Standard Type AC Three-Phase 4-Pole Vibration Motor is designed for professional industrial equipment where stable vibration and controlled material movement are required.

Silo and Hopper Discharge Systems

Bulk materials stored in silos and hoppers may suffer from poor flow, bridging, or blockage caused by moisture, pressure, or material characteristics.

The vibration motor can be installed as a Silo Vibration Motor or Hopper Vibration Motor to improve material discharge efficiency.

Typical applications include:

• Cementsilos
• Powder storage tanks
• Grain storage systems
• Feedhoppe
• Plastic pellet containers
• Chemical material storage equipment

By generating continuous vibration, the motor helps improve material flow and reduce production interruptions.

Vibrating Screens and Separation Equipment

The four-pole vibration motor provides stable vibration frequency, making it suitable for screening and separation processes.

Applications include:

• Mining vibrating screens
• Sand and gravel screening equipment
• Stonecrushing and screening systems
• Mineral separation machines
• Industrial sieving equipment

Compared with high-speed vibration motors, the 4-pole structure provides smoother vibration, which is beneficial for applications requiring controlled material movement.

Industrial Feeding and Conveying Systems

Many industries require continuous transportation of powders, particles, and bulk materials.

Applications include:

• Vibratingfeeders
• Vibratingconveyors
• Material handling systems
• Industrialseparators
• Automatic feeding equipment

The motor provides reliable vibration output for continuous production environments.

Food, Feed, Plastic and Chemical Industries

The vibration motor can also be applied in industries requiring controlled movement of lightweight materials.

Typical applications include: Foodd screening machine, Feed processing equipment, Plastic granule separator, Chemical powder handling system, Industrial filtration equipment

For food-related applications, anti-corrosion powder coating options are available to meet specific equipment requirements.

Key Features of Standard Type AC Three-Phase 4-Pole Vibration Motor

Stable 44-PoleLow-Speed Vibration Performance

The four-pole design operates at:

• 1500RPM at 50Hz
• 1800RPM at 60Hz

Compared with a 2 2-poleibration motor (approximately 3000/3600 RPM), the 4-pole structure provides lower frequency vibration with smoother operation.

It is suitable for:

• Screening
• Conveying
• Feeding
• Dehydration
• Materialclassification

Adjustable Centrifugal Force

The vibration force can be adjusted through eccentric block settings.

This allows equipment manufacturers to match the motor with different machine sizes and material loads.

The centrifugal force selection should consider:

• Total equipment weight
• Materialload
• Required vibration amplitude
• Workingconditions

Generally, the vibration force of the motor should be properly matched with the vibrating body to avoid insufficient vibration or excessive mechanical stress.

Heavy-Duty Industrial Construction

The motor is designed for long-term industrial operation.

Key features include:

• IP66mechanical protection
• H-class insulation
• S1continuous duty operation
• High-qualitybearings
• Greasetemperature range: -40°C to +120°C
• Lifetime lubrication design for reduced maintenance

The reinforced foot mounting structure improves installation stability during continuous vibration operation.

High-Temperature Resistant Copper Coil

The motor uses a pure copper coil with temperature resistance up to 180°C.

Benefits include: Better electrical conductivity, improved heat resistance, stable operation under continuous vibration, and longer service life

Strong Housing Structure

Housing materials are selected according to motor size:

• Frame10-50: Aluminum alloy housing
• Frame60 and above: Cast iron housing

The reinforced housing design improves mechanical strength and durability for industrial environments.

Voltage and Power Supply Options

Putian provides different electrical configurations for global industrial markets.

Available options include:

• 380~690Vvibration motor for industrial three-phase s

As a professional three-phase vibration motor supplier, Putian supports equipment manufacturers worldwide with flexible electrical solutions.

How to Select the Right 4-Pole Vibration Motor

1. Confirm Required Speed

Motor pole number determines vibration frequency.

• 22-polevibration motor: Approximately 3000/3600 RPM, suitable > for high-frequency applications such as compaction and clogging > 
• 4-pole vibration motor: Approximately 1500/1800 RPM, suitable > for general screening, conveying, and material 
• 6-pole vibration motor: Approximately 1000/1200 RPM, suitable > for heavy-duty conveying and low-frequency applications 

2. Select Proper Centrifugal Force

The vibration force should match:

• Equipmentweight
• Materialcapacity
• Required vibration effect

A motor that is too small may not provide enough vibration, while an oversized motor may increase energy consumption and mechanical stress.

3. Consider Installation and Environment

Before installation, customers should confirm:

• Mountingposition
• Number of motors required
• Equipment structure strength
• Operatingenvironment

For harsh industrial conditions, protection ratings such as IP66 should be considered. In cases where there is a special dust environment or gas environment, it is necessary to select explosion-proof vibration motors.
