VB Series Vibration Motors generate powerful directional or nonlinear vibrations by rotating eccentric blocks at high speed, producing a periodic centrifugal force (excitation force). This force is transmitted via the motor base to connected equipment, enabling controlled vibration in predefined directions or patterns. Designed as reliable excitation sources for a wide range of industrial vibration machinery, these motors are extensively utilized in sectors including power generation, building materials, coal and mining, metallurgy, chemical processing, light industry, and foundry applications. The series offers a power spectrum from 0.2 to 15 kW, available in 2, 4, 6, and 8-pole configurations, and delivers an adjustable excitation force ranging from 3 to 200 kN.
Core Structure:
1. Motor Body: Standard three-phase or single-phase asynchronous motor.
2. Eccentric Blocks: Installed at both ends of the motor shaft; the excitation force can be adjusted by changing the angle between the blocks.
3. Bearings: Special heavy-duty bearings designed to withstand high-frequency vibration loads.
4. Protective Housing: Typically made of cast iron, ensuring robust construction.
5. Cable Leads: Specialized vibration motor cables resistant to oil and bending.
Product Features:
1. Reasonable matching of excitation force and output, compact overall structure, lightweight, and small size for easy installation and use.
2. Smooth rotation and uniform vibration with low operating noise, suitable for environments with high noise requirements.
3. Fully enclosed design allows long-term stable operation in dusty environments (under non-explosive conditions).
4. Long service life: Bearing life is approximately 5,000 hours for 2-pole motors and 10,000 hours for 4/6/8-pole motors.
5. Stepless adjustment of excitation force: Achieved by adjusting the angle of the eccentric blocks to adapt to various working conditions.
6. Supports multi-motor combinations to form different vibration modes, meeting diverse process requirements.
7. Wide range of models and specifications for extensive compatibility with various vibration machinery and application scenarios.
Application Scenarios:
1. Vibratory Feeders: Ensure uniform feeding and prevent material blockages.
2. Vibratory Screening Machines: Screen and classify particles and powders.
3. Vibratory Conveyors: Transport materials horizontally or on an incline.
4. Vibratory Shakeout Machines: Used in the casting industry for mold removal.
5. Bin Dischargers: Prevent powder materials from arching in silos.
6. Vibratory Compaction: Compact concrete, sand, and soil.
Key Selection Points:
1. Excitation Force: Calculate the required excitation force (in kN) based on equipment mass and vibration amplitude requirements.
2. Power and Speed: Common pole configurations include 2-pole (approx. 3,000 rpm), 4-pole (approx. 1,500 rpm), and 6-pole (approx. 1,000 rpm). Speed affects vibration frequency.
3. Insulation Class: Typically Class F, resistant to temperatures up to 155°C.
4. Protection rating: Usually IP55, can be customized
