Coin Vibration Motor

LEADER Motor specializes in coin vibration motors, also known as shaftless or pancake vibration motors. The coin motor is unique in that its eccentric mass is located within a compact circular body, hence the name "pancake" motor. Due to their small size and thin profile (often only a few millimeters), these motors have limited amplitude, making them ideal for applications where space is limited.

It is worth noting that the starting voltage of the coin vibration motor is relatively high compared to the cylinder pager vibration motor. Typically, a coin motor requires about 2.3 volts to start (nominal voltage is 3 volts). If this is not considered in the design, it may result in the coin type vibration motor not starting when the application is in a certain orientation. This challenge arises because, in the vertical direction, the coin motor needs to exert enough force to move the eccentric mass to the top of the shaft during the initial cycle. To maximize the performance and reliability of a coin motor, it is critical to consider its specific characteristics and design requirements. By understanding these factors, designers can effectively incorporate coin vibration motors into their applications to achieve optimal results.

The Structure And Working Principle of ERM Motors


Coin vibration motors (also known as ERM motors) generally have a disc-shaped housing made of metal, with a small motor inside that drives an eccentric weight. Here are the general steps of how a coin vibration motor operates:

1. Power On: When power is applied to the motor, an electrical current flows through the coils inside, creating a magnetic field.

2. Attraction Phase: The magnetic field causes the rotor (eccentric weight) to be attracted towards the stator (coil). This attraction phase moves the rotor closer to the magnetic field, building up potential energy.

3. Repulsion Phase: The magnetic field then switches polarity, causing the rotor to be repelled from the stator. This repulsion phase releases the potential energy, causing the rotor to move away from the stator and rotate.

4. Repeat: The erm motor repeats this attraction and repulsion phase several times per second, causing rapid rotation of the eccentric weight. This rotation creates a vibration that can be felt by the user.

The speed and strength of the vibration can be controlled by varying the voltage or frequency of the electrical signal applied to the motor. Coin vibration motors are commonly used in devices that require haptic feedback, such as smartphones, gaming controllers, and wearables. They can also be used for alert signals, like notifications, alarms, and reminders.

Start Voltages

The start voltage and drive signals for a coin vibration motor can vary depending on the specific motor and the desired vibration strength. The start voltage for coin vibration motors typically ranges from 2.3V to 3.7V. This is the minimum voltage required to initiate the motor movement and vibration.

However, if the start voltage is too low, the motor may not start or may start slowly, resulting in weak vibration. This can cause the device to function improperly or not at all and may lead to user dissatisfaction. If the start voltage is too high, the motor may start too quickly and with too much force, causing damage to the internal components. This can also lead to a reduced lifespan and may cause additional problems such as excessive heat or noise.

Therefore, it's important to ensure that the start voltage is within the LEADER's recommended operating range and to avoid using voltages too high or too low. This can help to ensure proper motor operation, optimal vibration strength, and maximum lifespan.


Coin vibration motors are designed to be easy to mount and it usually comes with adhesive tape in the bottom. Two brands of adhesive tape are typically used on our coin vibrator motors. They have comparable specifications, and they are selected based on their capability to provide strong bonding to the motor.

1. Lead Wire: The coin motor can be connected to a power source through two wire leads. This type of wire uses imported wire (Sumitomo), which is made of halogen-free and Eco-friendly material. The wire leads are typically soldered to the motor terminals, and then connected to the power source by terminals or connectors. This method provides a simple and reliable connection, but may require additional space for the wire routing.

2. Connector: Many coin vibration motors have a mating connector that can be used for easy installation and removal. The connector provides a secure and repeatable connection that does not require soldering. However, this method may add cost.

3. Flexible Printed Circuit Board (FPCB): An FPCB is a thin and flexible circuit board with conductive traces that can be used to connect the motor to other components or circuits. This method provides a compact and low-profile solution for installing the motor, and also allows for customization of the circuit layout. However, it may require specialized manufacturing processes and can be more expensive than the lead wire type.

4. Spring Contacts: Some coin vibration motors come with spring contacts that can be used to make a temporary or semi-permanent connection. The spring contacts provide a low-cost and simple installation method that does not require soldering or wires. However, they may not be as secure or reliable as other methods, and may require additional mechanical support.

The choice of installation method will depend on the specific requirements of the application, including space limitations, vibration strength, and ease of installation and maintenance. LEADER's technical experts will provide professional advice based on their project experience during the customer's design phase.

It's important to consult with LEADER for specific recommendations and testing before making a final selection.

What is the difference between a coin vibration motor and a linear vibration motor?

A coin vibration motor and a linear vibration motor are two different types of motors used for vibration. A coin motor typically consists of a rotating offset weight that creates an unbalanced force to produce vibration, while a linear motor consists of a moving mass that oscillates along a linear path to produce vibration. Linear motors are AC- driven and require additional driver IC. However, coin motors are easier to drive by supplying DC power according to the voltage range recommended in the specification.

How Coin Vibration Motors Work in Wearable Devices?

Vibration motors, also known as haptic motors, are commonly used in wearable devices such as smartwatches and fitness trackers to provide users with tactile feedback.

These motors work by converting electrical energy into mechanical vibrations that can be felt. The mechanism behind vibrating motors involves an unbalanced mass attached to the motor shaft. As the motor rotates, the unbalanced mass causes the motor to vibrate. This vibration is then transmitted to the wearable device, allowing the user to feel it.

To control the vibration motor, a drive circuit is usually used. The drive circuit regulates the amount and frequency of electrical energy supplied to the motor, allowing the intensity and pattern of vibration to be adjusted. This allows for different types of feedback sensations, such as a slight vibration or a stronger buzz.

In wearable devices, vibration motors are often used to provide notifications, alerts, and alerts. For example, a smartwatch can vibrate to notify the wearer of incoming calls or messages. The vibration motor also provides tactile feedback during exercise, helping users track their fitness goals.

Overall, vibration motors are crucial in wearable devices as they provide tactile feedback, enhance the user experience and keep the wearer connected and engaged with their device.

What Is the Voltage of a Coin Vibration Motor?

Typically this is around 2.3v (all coin vibration motors have a nominal voltage of 3v), and failure to respect this could result in motors not starting when the application is lying in certain orientations.

What Are the Different Types of Coin Vibration Motors?

Our coin types vibration motor have 3 types, brushless types, ERM eccentric rotating mass type, LRA linear resonant actuator type. Their shape is a flat coin button-type.
