Why Does Putian Set Large MVE Series Vibration Motors to 70% Vibration Force by Default?

Choosing the right vibration motor is not only about achieving up to excitation force—it is also about ensuring safe commissioning, reliable operation, and long-term equipment protection. This is why Shenzhen Putian Vibration Motor Co., Ltd. configures its Putian MVE Series Vibration Motors with a 70% factory default vibration force for models with frame size 75 and above.

This carefully engineered setting helps customers start their equipment safely while providing the flexibility to increase vibration force when production demands require it.

Why Is the Factory Default Set to 70%?

During equipment installation and commissioning, many vibrating machines are tested without material load. Running a large vibration motor at full excitation during no-load testing may generate excessive vibration, potentially affecting machine stability or causing unnecessary stress on the equipment.

To reduce this risk, Putian MVE Series Vibration Motors leave the factory with the eccentric blocks adjusted to approximately 70% of the up to vibration force. This configuration allows users to complete installation, alignment, and initial commissioning with greater confidence while minimizing the possibility of equipment damage caused by excessive vibration.

This safety-focused design reflects Putian's commitment to both equipment performance and customer protection.

Adjustable Vibration Force for Different Production Needs

Every production line operates under different working conditions. Material density, feeding volume, screen size, and machine structure all influence the required vibration force.

The Putian MVE Series Vibration Motor is designed with an adjustable eccentric block system, allowing users to fine-tune the excitation force according to actual operating requirements.

If higher vibration is needed after commissioning, users can simply:

• Remove the side covers.
• Adjust the angle of the eccentric blocks.
• Ensure both ends are adjusted to the same angle.
• Reassemble and restart the equipment.

This straightforward adjustment process gives operators greater flexibility without requiring replacement parts or specialized modifications.

Maximum Excitation with Proper Eccentric Block Alignment

The eccentric blocks are the core components responsible for generating centrifugal force inside a vibration motor.

When the two eccentric blocks completely overlap, the motor produces its up to vibration force, making it suitable for applications requiring stronger material movement or higher processing capacity.

However, maintaining identical eccentric block angles on both ends is essential. Correct alignment ensures balanced operation, stable vibration output, and reduced mechanical stress on the motor and connected equipment.

Proper adjustment not only improves performance but also helps extend the service life of bearings, shafts, and supporting structures.
