Top 10 Questions About Coin Vibration Motors (Answered by a Manufacturer)

As a leading manufacturer of coin vibration motors, we often receive a wide range of questions from product designers, procurement managers, and businesses looking to integrate these compact devices into their products. To help you gain a clearer understanding, we’ve compiled the top 10 most frequently asked questions about coin vibration motors, along with detailed answers. Whether you’re curious about samples, patents, delivery times, or customization options, we’ve got you covered.​

1. Do you provide free samples of coin vibration motors? ​

Yes, we do. We understand that testing a coin vibration motor in your product is crucial before making a bulk order. We offer 5-10 free samples of our standard coin vibration motors to qualified customers. Reach out to our sales team with your product details, and we’ll arrange the samples promptly.​

2. Are your coin vibration motors patented to avoid infringement issues? ​

 Absolutely. All our coin vibration motors are backed by multiple patents. These patents cover key design features, manufacturing processes, and performance optimizations, ensuring that our customers won’t face any intellectual property infringement risks when using our products. We can provide patent certificates upon request for your peace of mind.

3. What is the typical lead time for coin vibration motor orders? ​

For standard coin vibration motor models, such as our best-selling 8mm pancake vibration motors, we maintain large inventories of the bare motor. This allows us to fulfill most orders within 1-2 weeks. For customized coin-type vibration motors or bulk orders exceeding 10,000 units, lead times may extend to 3-4 weeks, depending on the complexity of your requirements. We’ll always provide a clear timeline when confirming your order.​

4. Can you customize coin vibration motors according to specific requirements? ​

Yes, customization is one of our core strengths. We can tailor coin vibration motors to match your product’s needs, including parameters like size (from 6mm to 20mm in diameter), voltage (1.2V,3V, 4V, etc.), current, vibration intensity, and connection type (solder pads, wires, etc.). Simply share your technical specifications, and our engineering team will develop a custom flat vibration motor solution that fits seamlessly into your device.​

5. What is the operating voltage range of your coin vibration motors? ​

Our standard coin vibration motors typically operate within a voltage range of 2.3V to 3.3V, with 3V being the most common option for consumer electronics. Customized models can be designed to work with higher or lower voltages, depending on your product’s power supply. It’s important to note that vibration intensity increases with voltage, so we’ll help you select the right range for your desired feedback strength.​

6. How long do coin vibration motors last under normal use? ​

A well-designed coin vibration motor can last 80,000 to 100,000 cycles under normal conditions of 1s on, 1s off. Our pancake vibration motors are built with high-quality bearings and durable materials to ensure long-term reliability.​

 7. What is the maximum vibration intensity of your coin type vibration motors? ​

Vibration intensity (measured in G-force) varies by model. Our smallest 7mm coin vibration motors deliver around 0.4G, while larger 12mm pancake vibration motors can reach up to 2.5G. This flexibility makes them suitable for everything from subtle notifications in earbuds to strong haptic feedback in gaming controllers. We’ll help you choose a flat vibration motor with the right intensity for your application.​

8. Are coin vibration motors waterproof? ​

Standard coin vibration motors are not inherently waterproof, as their internal components (like the rotor and bearings) are exposed to air. However, we offer waterproof coatings and sealed enclosures for custom orders, making them suitable for devices used in wet environments—such as fitness trackers worn during swimming or medical devices used in hygiene-sensitive settings. Discuss your waterproofing needs with our team for a tailored solution.​

9. What industries commonly use your coin vibration motors? ​

Our coin vibration motors are widely used across industries, including consumer electronics (smartphones, smartwatches, wireless earbuds), wearables (fitness trackers, smart rings), gaming (mobile controllers, handheld game consoles), medical devices (portable monitors, pill reminders), and automotive (key fobs, in-car touchscreens). The compact size of our pancake vibration motors makes them ideal for any product requiring space-efficient tactile feedback.​

10. How do coin vibration motors compare to linear resonant actuators (LRAs)?​

Coin vibration motors (a type of eccentric rotating mass motor) are generally more cost-effective and simpler to integrate than LRAs. They offer adjustable vibration intensity via voltage control and work well for continuous or long-duration feedback. LRAs, on the other hand, provide sharper, more precise vibrations but are pricier and require specific frequency tuning. For most consumer products needing reliable, budget-friendly haptics, a coin type vibration motor is the preferred choice.​
