Due to their small size and enclosed vibration mechanism, coin vibrating motors are a popular choice for many applications. A coin vibration motor may be used in applications such as the smart watches, fitness trackers (as shown in the right gif) and other wearable devices. They are widely used to provide the user with discrete alerts, precision alarms or haptic feedback. Referring to the figures on the below of the page, NFP supply our coin motor with a variety of connectors, spring contacts, FPC or with bare contact pads. If the quantity merits, we can design a custom FPC for your application. The Horizontal direction Vibration through losing body balance by eccentric weight Rotating. Eccentric Rotating Mass Coin Rotating eccentric weight is to lose body balance while the motor vibration occurs in the Horizontal direction. Indicating the received signal into vibrations in the Mobile device is a rotary type with a small motor. The operation is possible with DC Power On/Off, does not require a separate Drive IC. General Features - High Vibration Force, Smooth Rotation, Easy build up Smartphone, Tablet PC, Wearable, Toy, Game Consoles and Others.

 

NFP motor currently produces coin vibration motors, also known as shaftless or pancake vibrator motors. Pancake coin motor are compact and convenient to use. They integrate into many designs because they have no external moving parts, and can be affixed in place with a strong permanent self-adhesive mounting system. Pancake coin vibration motors can easily be moulded to accept the coin motor form of our shaftless vibration motors. Within the coin motor range, we offer both leaded and spring & pad pcb motors & other mountable versions. Like all of our coin vibration motors, we are happy to quote for micro coin vibration motor to the base design such as a modification to the lead length and pancake coin motor connectors.

 

Coin motor or 'pancake' motors use the same operating principle as pager motor (ERM), however their eccentric mass is kept in their small circular body (which is where they get their names from). Brushed coin vibration motors are constructed from a flat PCB on which the 3-pole commutation circuit is laid out around an internal shaft in the centre. They are restricted in amplitude because of their size with extremely low profiles (only just a few mm!) which make them popular in applications which space is restricted. Coin vibration motors have a relatively high start voltage (compared to cylinder pager vibration motors) which must be considered in designs. Typically this is around 2.3v (all coin motor have a nominal voltage of 3v), and failure to respect this could result in coin motor not starting when the application is lying in certain orientations. This problem arises because in the vertical orientation, the coin motor must force the eccentric mass over the top of the shaft on the initial cycle.

Coin Vibration Motor - Brushless Vibration Motor 3V BLDC Type

- These BLDC Motors have much longer lifetime than the normal brush type motors. At the test mode of 0.5s On 0.5s Off as one cycle, the total lifetime can be 1 million cycles.

 

- To use these BLDC Motors, the method is same as that of normal brush type motors, because the IC drivers are embedded inside. It has no interference to the users PCB circuit.

 

These new 3V(all coin vibration motors have a nominal voltage of 3v) vibration coin motor were made in this year 2016. You can find the fit one from the list with more different dimensions (diameter range from 7mm-14mm). Our coin or pancake vibrating motors are all Eccentric Rotating Mass (ERM) motors. These quality vibrate coin motor are used in smartwatch, user input feedback, medical, touch sensory, automotive, consumer, and industrial products. Specific applications in which our mini coin type vibrating motors could be used are in feedback of handheld devices, coin vibrating motors for touch screen feedback, vibration coin motor for emergency alerting, vibrating coin motor for simulations, coin vibration motors for video gaming, and other operator feedback applications.

The coin motor that are used in the phones are called Q-Coin motor as they are in a shape of a coin. They are of permanent magnet type accepting two leads for positive and negative DC voltages. The circuitry that operate this motor just can switch on the disk motors for a specific period of time and can change its rotation direction. All other parameters of coin vibration are set by motor's design.

 

The coin motor is mounted on smart phones, tablet PCs, game consoles and handheld devices to provide a notice function through its vibration, and also to provide users with the “feel of touch” (haptic fuction) through the vibration of the coin motor. Supports the small linear actuators and the piezo actuators to provide coin vibration motors that are applicable for smart phone and tablet PCs. A linear actuator provides vibration through electromag-netic force and resonance mode created just by sine wave-generated vibration In a mobile device, it realizes the haptic functions by providing vibration upon call reception and quick vibration upon touch.
