Vibration motor is a commonly used vibration equipment, widely used in vibrating screen, vibrating conveyor, vibrating feeder and other fields. Adjusting the vibration size is one of the important operations of using vibration motor.Adjusting the vibration size of a vibration motor can be done in a few ways, depending on the specific motor and application.

1. Changing the Voltage or Current

For motors with variable voltage/current control: Some vibration motors have built-in controls to adjust the voltage or current supplied to the motor. This directly impacts the motor’s speed and, consequently, the vibration amplitude.

Adjusting the power supply: If your motor doesn’t have built-in controls, you can adjust the voltage or current from the power source. However, be cautious: excessive voltage or current can damage the motor. Always consult the motor’s specifications and use the recommended voltage and current range.

2. Adjusting the Eccentric Mass

Some vibration motors have adjustable eccentric weights: These weights are positioned off-center on the motor shaft, creating an imbalance that causes the vibration. By moving the weights closer or farther from the center, you can increase or decrease the vibration amplitude.

Replacing the eccentric mass: In some cases, you might need to replace the existing eccentric mass with one of a different weight to achieve the desired vibration size.

3. Using External Mechanisms

Spring adjustment: If the vibration motor is mounted on a spring system, adjusting the spring tension can affect the vibration amplitude. Tighter springs will generally result in smaller vibrations.

Adding or removing mass: Adding mass to the vibrating system (e.g., to the vibrating table or platform) will usually reduce the vibration amplitude. Conversely, removing mass will increase it.

General Considerations

Motor specifications: Always consult the motor’s specifications and operating manual for recommended adjustment methods and safe operating limits.
