what is coin vibration motor?

coin type motor

Coin type vibrating motor with lead wire (brush type) φ8mm – φ12mm – Pancake Types

Leader Microelectronis Motor now offering 3v Coin Type Motor, also known as shaftless or pancake vibrator motors. Latest Coin Vibrating Motors. Warehouse Prices, World Class Customer Service. The diameter of them is range from Ø8mm – Ø12mm. Pancake motors are compact and convenient to use. Enclosures can be moulded to accept the coin form of our shaftless vibration motors easily. Within the coin motor range, we offer both leaded and spring & (black foam) pad mountable versions. This is a small flat coin vibration motor with adhesive backing. Coin Dc Motor Vibration Motor are used today in an endless number of applications; these are quality motors used in medical, automotive, consumer, and industrial products. Specific applications in which our vibrating motors could be used are in feedback of handheld devices, touch screen feedback, emergency alerting, simulations, video gaming, and other operator feedback applications. microtek vibrating motor

Coin motor applications

Due to their small size and enclosed vibration mechanism, coin vibrating motors are a popular choice for many different applications. 3.0v dc vibrator 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. Leader 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. ultrathin vibrating motor

Coin type coreless motor working principle of mechanism

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.
