DC Vibration Motor Module – PWM Controlled Haptic Feedback Module

Product Description

The DC Vibration Motor Module is a compact and versatile haptic feedback module designed to generate physical vibrations in electronic and embedded projects. It converts electrical signals into mechanical vibration and can be used as a silent alert, notification, feedback, or status indicator.

The module features a built-in MOSFET drive circuit and can be activated using a high-level trigger signal. Its vibration intensity can be adjusted using PWM (Pulse Width Modulation) control, allowing developers to create different levels of haptic feedback according to the application requirements.

With its compact motor and small PCB size, the module is suitable for portable electronics, wearable devices, interactive projects, robotics, educational electronics, and custom embedded systems. It can be easily controlled by popular development boards such as Arduino UNO R3, Arduino Mega2560, and other compatible microcontrollers.

The module uses a small 10mm flat vibration motor and provides a rated speed of approximately 9000 RPM, making it suitable for applications that require noticeable tactile feedback while maintaining a compact form factor.

Specifications

Working Principle

The module uses a small DC vibration motor to convert electrical energy into mechanical vibration.

A high-level trigger signal from a microcontroller activates the motor through the onboard MOSFET drive circuit. When the control signal is removed, the motor stops.

For adjustable vibration intensity, a PWM signal can be applied to the control input. By changing the PWM duty cycle, users can control the effective motor power and produce different levels of vibration.

This makes the module useful for applications requiring different tactile feedback patterns, such as alerts, notifications, button feedback, timers, and interactive controls.

PWM Control

The vibration intensity can be adjusted using PWM control from a compatible microcontroller.

A lower PWM duty cycle can produce weaker vibration, while a higher duty cycle can increase the vibration intensity. The exact response may vary depending on the motor, power supply, PWM frequency, and connected controller.

PWM control allows developers to create customized vibration patterns for different events or notifications.

Design and Construction

The module uses a compact PCB with an integrated vibration motor and MOSFET driving circuit. Its small size allows it to be integrated into portable devices, enclosures, wearable products, robots, and other compact electronic assemblies.

A fixed 3mm mounting hole with approximately 15mm pitch is provided for secure mechanical installation.

The flat 10mm motor design helps minimize the overall size of the module while providing noticeable vibration feedback.

Product Disclaimer

Product images are shown for illustrative and representational purposes only. The actual module may vary slightly in PCB colour, component placement, motor appearance, connector arrangement, dimensions, or labeling depending on the manufacturing batch.

Development boards, cables, batteries, wires, mounting hardware, and other accessories shown in product images are not included unless specifically mentioned in the package contents.

Technical specifications such as current consumption, vibration strength, and operating behaviour may vary slightly depending on the motor batch, supply voltage, PWM settings, and operating conditions.

Important Notes

Starting Voltage

The specified starting voltage is approximately 3.7V DC. Ensure that the power supply provides sufficient voltage for the motor to start reliably.

Power Supply

Use a suitable power source within the specified 3–5.3V DC operating range. Ensure that the supply can provide enough current for motor startup and operation.

Mounting

Use the provided 3mm mounting hole to securely fix the module. Proper mounting can help prevent unwanted movement of the board during high-intensity vibration.

PWM Control

PWM can be used to adjust vibration intensity, but the actual vibration response depends on the connected controller, PWM frequency, duty cycle, supply voltage, and motor characteristics.
