Vibration Motor/Exciter for Screening Systems

Product Specifications

Technical details and manufacturing context for Vibration Motor/Exciter

Definition

In a Product Screening System, the vibration motor/exciter is the core component that produces oscillatory motion to vibrate screening surfaces, enabling efficient separation, sorting, and classification of materials based on size, shape, or other physical properties. This component is typically mounted on the screening machine's frame or directly on the screen deck. It converts electrical energy into mechanical vibration through an unbalanced rotating mass (eccentric weight) or electromagnetic force, creating centrifugal force that induces controlled oscillations in the screening equipment. The vibration amplitude and frequency can be adjusted to suit different material properties and screening requirements. The motor's rated power ranges from 0.12 to 7.5 kW, with centrifugal force from 1 to 100 kN, vibration frequency from 25 to 60 Hz, and amplitude from 1 to 5 mm. Rated voltage options are 220–690 V AC (IEC 60038), rated current from 0.5 to 15 A, protection class IP54–IP65 (IEC 60529), insulation class F–H (IEC 60085), operating temperature -20 to 60 °C, weight 15–500 kg, and mounting footprint 100–500 mm. Materials used include electrical steel, copper windings, and high-strength alloy steel. These parameters are reference ranges; actual values must be confirmed with the manufacturer for specific models and applications. Standards listed are for verification purposes and do not imply certification. When selecting a vibration motor, consider the screening area, material characteristics, required throughput, and mounting compatibility. Verify bolt hole patterns, shaft dimensions, and electrical connections. Regular maintenance includes checking for abnormal noise, excessive heat, and loose mounting bolts. Failure signs include reduced vibration amplitude, increased current draw, or overheating. Always consult the manufacturer's documentation for safe operation and maintenance.

Working Principle

The vibration motor/exciter converts electrical energy into mechanical vibration via an unbalanced rotating mass (eccentric weight) or electromagnetic force. The rotating eccentric mass creates a centrifugal force that induces controlled oscillations in the screening equipment. The frequency and amplitude of these oscillations are determined by the motor speed and the mass configuration. This mechanical vibration is transmitted to the screening surface, causing materials to move and separate based on size and other properties.

Frequently Asked Questions

What is the typical power range for a vibration motor?

The rated power typically ranges from 0.12 to 7.5 kW, depending on the screening area and application. Higher power is used for larger screening surfaces.

How do I determine the required centrifugal force?

Centrifugal force ranges from 1 to 100 kN. It determines vibration amplitude and material flow. The required force depends on the material weight and desired screening efficiency.

Can the vibration frequency be adjusted?

Yes, the vibration frequency is adjustable, typically between 25 and 60 Hz. Adjustments are made to suit different material properties and screening requirements.

What protection class is suitable for dusty environments?

For dusty environments, a protection class of IP65 is recommended. The available range is IP54 to IP65, per IEC 60529. Always verify the actual rating with the manufacturer.
