0720 Coin Vibration Motor for Hand Massager
No driver IC required | Ultra compact 7mm diameter | 3V DC rated voltage | RoHS compliant | Operating: -20℃ – +70℃ | Storage: -40℃ – +85℃ | Insulation resistance 10MW(min) | Available with wires or connectors
The 7mm diameter, 2mm thickness motor is actually the smallest motor in the world. It has longer lifetime with much higher price, and with a built-in IC driver. It works at DC as the brushed one. Vibration force is 0.55g.
The coin vibration motor mainly consists of a rotor made of permanent magnet material and a stator with a coil winding. It has a lot in common with DC motor, stator and rotor structure is almost the same (the original stator into rotor, rotor into stator), the winding wiring is basically the same.
However, there is one obvious structural difference: brushless DC motors do not have commutators and brushes as in DC motors. Instead, they use a position sensor.Brushless DC motor cannot automatically commutate (phase).

(1) These Motors have much longer lifetime t. At the test mode
of 0.2s On 0.1s Off as one cycle, the total lifetime can be 50,000 cycles.
(2) To use these Coin Vibration Motors, the method is same as that of normal brush type motors,
Outline Drawing for the Small DC Coin Motor
ERM mini vibration motors also called small coin vibration motor, compact and convenient to use, no external moving part. Used in handheld instruments haptic. 0720 Series Coin Vibration Motors – 7mm x 2mm, 3 V, coin vibration motor for light weight wearable devices. Only 7 mm in diameter, 0720 series is currently the smallest small brush coin vibration motor on the market. It was designed for devices requiring vibration alerts or haptic feedback. Because small coin vibration motor produces a relatively low vibrational force of 1.0 G, this motor is best suited for use in light weight devices placed directly against the user’s skin. It may be driven by either DC voltage or a PWM signal. A driver IC is not required but may be used to produce various haptic effects. Custom foam pads, or PSA are available for mass production orders. If a higher vibrational force is required, please consider using one of MDM’s larger sized coin vibration motors. These mini vibration motors range from 6 mm to 12 mm in diameter and can generate vibrational forces of up to 2.00G.
Coin motor Features:
1. Small size, light weight.
2. low noise, small starting voltage, no communication interference, strong practicality,easy installation, and mature technology.
3. Low price.
Disadvantage: Life time is difficult to increase to 1 million times. Application range: Mobile phone, high-grade vibration massage care equipment, electronic watches, quartz watches, smart toys, medical equipment, electronic beauty products, etc.
The beauty equipment in the picture above uses our smallest brush coin vibration motor 0720, which has a long service life, lower power consumption, and a compact dimension. This tiny vibration motor’s diameter is only Φ7mm. It’s a brush type coin vibration motor and it has no IC driving the rotation. The advantage showcases its long lifecycle – 50000 cycles lifetime. 0720 Coin Vibration Motor for Hand Massager is reliable.
In addition, we have other brush flat vibration motors, 8mm diameter 0820,0827,0830
Smallest ERM Motors are coil of wire, Best choice for light-weight wearable device haptic feedback function. Coin vibration motors, flat vibration motors are also known as pancake motors, Kegumotor can offer the coin type vibration motor diameter range from Ø6mm to Ø12mm, you can ask for any of the coin vibration motor data-sheet by the below form. Pancake vibration motor erm type is cheaper than linear resonant actuators.
For assistive applications, haptic feedback can be used as a virtual crutch for visually impaired people. The distance sensor can sense the object in front of the user, and tactile feedback will provide the distance between the object and the user. Haptic feedback also provides left and right navigation commands when connected to the navigation function on a smartphone.
Other applications: Lightweight wearable devices, Cell phones, pagers & other Medical instruments & equipment, Haptic feedback applications, Toys, PDAs, Shavers, Personal alarms, Communication equipment, Buttons feedback, Massager bras.
The large coin vibration motor is designed for devices requiring vibration alerts or haptic feedback. Coin vibration motor compact feature let it convenient to use in any lightweight wearable devices. It’s easy to integrate the vibration motor coin into many designs because they have no external moving parts, long life cycles.
Typically the pancake vibrator motor is produced in the following way: the black cotton pad is placed on the top and the double-sided adhesive tape is placed on the bottom (the installation is convenient for operation) of the coin motor.
Customer can add black foam of different thickness (0.1mm-0.5mm is available) according to the application request, or the coin vibrator can be customized without adding black foam, double-sided adhesive is the same way as the top black foam. For double-sided adhesive we usually use 3M brand tape to ensure that the paste is durable…
What can we use pancake vibration motor? For example: Remind users in advance to turn left direction or right direction with clear vibrating alert; Remind drivers when users have reached the pre-set mileage. When a certain dangerous driving speed is reached, the rider is reminded to pay attention to safety.
Help users maintain pace or rhythm by providing vibrating metronome; Remind users when receiving text messages or when a call comes in. Use clear beeps to remind users that they should go to exercise.
Another high-tech application is a belt that supports haptic feedback, which can provide intermittent navigation prompts for soldiers wearing this belt in noise-sensitive environments. When soldiers cannot talk, they can use haptic feedback to communicate.
Tactile feedback prompts can be GPS-based local navigation directions, more complicated communication between two soldiers or a group of soldiers, or even vibration feedback to avoid collision between a remote control robot and an obstacle. You can take a look at the active belt project sponsored by the Defense Advanced Research Projects Agency.
Tactile sensation is ideal for alerting people when other feelings are occupied, or to enhance audio or visual feedback. Here are some great features you can implement with haptic feedback:
Vibration feedback in shoes when walking or running. When you reach the turn, the shoe on the left or right foot will tell you the next direction by vibration alerting. This is very useful for runners, climbers, hikers, bike lovers, and tourists in strange cities.
They need to know the direction of progress during continuous exercise. Haptic feedback applications such as these can also help people with visual impairments to easily walk around the city.
Coin vibration motor is a typical ERM (eccentric rotating mass) actuators. It is a brushed type vibrating motors that are widely used for smart watches, fitness trackers and other wearable devices. The function of the coin vibrating motos are used for providing customer with haptic feedback, alarms or massaging. Our coin type vibration motors have different kinds of sizes for customers’ variety of applications.
These ERMs coin vibration motos are super cheap compared with LRA or BLDC type vibrating motors. Our coin vibrating motors can be customized as your need, such as customized lead wire, adding variety connectors to coin motors, FPC(such as the following model: 0820) or with bare contact pads.
More and more small vibration motors are used in the beauty industry. Vibration can help skin cells to better absorb nutrients and help skin care. Beauty, medical equipment uses tiny vibration motors to achieve subtle vibration effects.
Typical Application:
This tiny vibration motor is used for smartphone, watch, brachet, cosmetic, electronic cigarette, etc.
Except the diameter 6mm brushless motor, we also have many other tiny vibration motors, diameter 7mm, 8mm
and 10mm coin type motor can be used for smartphone.
