Vibration motors are manufactured based on two technologies - ERM and LRA. The first technology uses the unbalanced mechanical load on the rotor by mass. This load as the shaft rotates generates a centrifugal force. As a consequence, vibrations arise, which we owe the name of this group of engines. The second technology - LRA - uses a linear resonator in which a small ferromagnetic element is connected to a spring. Under the influence of a magnetic field, it vibrates and drives a vibration motor.
Both types of vibration motors are available in the offer of the online shop with electric motors Botland. Here you will find products that differ in both physical sizes and detailed technical parameters. In complex projects, vibration motors can be connected in series, e.g. 4 3-volt motors and powered by a battery or a 12V power supply.

The professional use of vibration motors
The vibration motors are designed to perfectly generate and handle vibrations. These are devices designed and adapted to drive vibration installations. When it comes to the use of vibration motors, these types of components can be found in many different kinds of applications such as transport vibrating chutes, vibrating pipes, screening conveyors, screening machines and sorters. In addition, vibration motors are also used for vibrating feeders, crushing grates, vibrating stands, resonating conveyors, compactors and vibratory mills.
Obviously, in the field of DIY projects, our imagination is the main driving force determining what components and components we will use to build a given model. Nevertheless, as can be seen in the examples above, vibration motors are among the more advanced components and are mainly used in industry and professional tasks.
Vibration motors – mechanical technology implemented in the first mobile phones
Unbalance is the core of the vibration motors. Unbalance is understood as a constantly rotating mass. It is unevenly distributed in its rotational symmetry, as a result of which it causes constant vibration as it rotates. These types of vibrations can be modified with weights and counterweights. The main axis of operation of vibration motors is the use of the above phenomenon put in motion of unbalance.
Haptic technology and vibratory alerting are also important. These are the two most popular methods of implementing vibration signals in electronic devices. The first, haptic technology, uses vibrations with different duration of pulses between individual vibrations, which allows you to easily distinguish the signaled information from each other, and vibrational alerting uses the effect of a linear increase in vibration intensity. The first mobile phones are a perfect example of using the above technology.
As we remember well, these devices had been implemented with a built-in small vibration motors that signaled an incoming call or text message with short vibration signals. Later, in the case of an incoming message, they vibrated the word "SMS" with Morse code. Nowadays, vibration signals are also used in many software applications for smartphones, but the technology of generating vibrations itself has been significantly modified and changed.
Vibrator motors – other practical applications
The applications of vibration motors are, in contrary to what we may think of them, very wide. Moreover, many models have been equipped with additional functionalities. Feedback is a good example. With the use of feedback in such devices, vibration motors can be used for maintenance-free cleaning of gutters in the event of clogging, e.g. with leaves.
The above cleaning methods require the use of motors with higher torque. On a smaller scale, regarding mini-motors, the devices are used in chemical laboratories for the preparation of emulsions, and in home applications as a drive for an electric toothbrush and a drive for an air pump for filling the cuff in an electronic device for measuring blood pressure and heart pulse. The electric motor can also be used in precision low-power drive systems.
