The SV Long-Rod Ex-Proof Vibration Motor is a heavy-duty industrial vibration solution designed for continuous operation in demanding environments. Compared with standard compact vibration motors, the SV series features an extended long-body structure with end foot mounting, providing improved mechanical stability and reliable vibration transmission for large-scale equipment.
It is mainly used for material conveying, screening, dewatering, compaction, sizing and bulk material discharge applications where stable vibration performance and long service life are required.
The explosion-proof design makes it suitable for industries involving dust, combustible materials or harsh working conditions, including mining, recycling, food processing, chemical processing and heavy industrial applications.
By adjusting the eccentric blocks installed on both ends of the rotor shaft, the centrifugal force can be precisely controlled to match different equipment requirements.

Simply speaking, the SV Long-Rod Ex-Proof Vibration Motor is a motor that converts electrical energy into controlled mechanical vibration.
The long-rod structure improves vibration transmission and mechanical strength, making it suitable for larger machines that require continuous and stable vibration output.
The vibration force is generated by adjustable eccentric blocks mounted on both ends of the rotor shaft.
A single vibration motor can create circular vibration movement, while two motors installed in opposite rotation directions can generate linear vibration movement.
This allows the same vibration motor technology to be adapted for different equipment designs, including feeders, screens, conveyors and discharge systems.
