The definition of vibration motor
The vibration motor is a coreless DC motor whose size is compact. The original purpose of this motor is to alert the user from receiving the call without sound/vibrating. The main feature of this motor is, it has magnetic properties, lightweight, and motor size is small. Based on these features, the motor performance is highly consistent. The configuration of these motors can be done in two varieties: one is a coin Model, and another one is a cylinder Model. The vibrator motor specifications mainly include type, max Operating Torque, max, centrifugal force, weight Range, rated Current, and Output.
The working principle of vibrator motor
The cylindrical shape is also called a rod-type vibration motor. This vibration motor is essentially improperly balanced. In other words, there is an eccentric weight on the rotating shaft of the vibration motor, which generates centrifugal force when it rotates. This unbalanced force displaces it. Its high-Speed displacement causes it to swing, which is called “vibration”. The wobble can be changed by the weight mass you attach, the weight’s distance to the shaft, and the Speed at which the motor spins. Secondly, the centrifugal force generated by the rotation of the unbalanced weight will cause it to vibrate along the two axes (Z-axis and X-axis).
Besides, the centrifugal force can be calculated by the formula in Figure 3. According to the relationship between the various components in the formula, it is easy to see that the mass of Chen 8 with greater weight offset from the shaft, and it will generate a greater force and, therefore, a greater vibration amplitude. Besides, increasing the Voltage supplied to the motor will increase its Speed, thereby increasing the frequency and amplitude of vibration.
Vibrator motor applications
The applications of the vibrator motor include the following:
- Handsets, cell phones, pagers, and so on.
- Material handling devices like conveyors, feeders, and vibrating screens.
- Hoppers, silos to stop blocking the flow of material.
- Compacting machines & foundry shakeouts for quick & proficient operation.
