Product Description
A vibration motor generates mechanical oscillations through a rotating eccentric mass. When DC voltage is applied, the eccentric mass rotates on the motor shaft and causes the entire housing to vibrate. This simple design (ERM, Eccentric Rotating Mass) does not require a special driver component for control; the motor operates directly from a DC power source.
The two connection wires are color-coded and enable straightforward polarity identification. When operating with a microcontroller, a switching transistor is usually connected upstream, as the controller outputs cannot supply the required motor current directly. For simple test setups, however, a 3 V DC battery or power supply connected between the two wires is sufficient.
The flat, disk-shaped design and minimal weight of approximately 1 g make this motor ideal for applications with limited space. Typical applications include vibration in mobile phones for calls and notifications, feedback effects in game controllers, or tactile feedback in wearable devices. The metal housing provides mechanical robustness and good heat dissipation.
When integrating the motor into a project with a microcontroller, a separate power supply for the motor is also required in addition to a switching transistor if it requires more than 50 mA. The operating temperature range of -20 °C to 70 °C defines the limits for ambient conditions. During continuous operation, vibrations may become noticeable after extended running times.
Safety Notice
This component is intended exclusively for building prototypes and for testing and development purposes and is not suitable for installation in household electrical circuits. Before commissioning, consult a qualified electrician when operating with power supplies above 12 V or in safety-critical applications. Observe the polarity of the connection wires.
