A coin vibrator motor is a type of small electric motor commonly used in various devices such as mobile phones, pagers, and wearable devices. It is designed to provide vibration feedback or alert users to incoming calls, messages, or notifications. The motor consists of several key components, including a magnet.
The magnet in a coin vibrator motor plays a crucial role in its operation. It is typically made of a permanent magnet material, such as neodymium (NdFeB) or ferrite. The magnet is responsible for generating the magnetic field necessary for the motor’s functionality.
When an electric current flows through the motor’s coil, it creates a magnetic field. This magnetic field interacts with the magnet, causing it to rotate. The rotation of the magnet generates vibrations that are transferred to the device’s casing, creating the desired vibrating effect. Micro Neo Coin Magnet N45 for Precision Micro Drives
The size and strength of the magnet used in a coin vibrator motor depend on various factors, including the desired vibration intensity and the size constraints of the device. Neodymium magnets are often preferred due to their high magnetic strength and compact size. They offer excellent performance in small form factors.
It is worth noting that the magnet in a coin vibrator motor is typically cylindrical or disc-shaped. This design allows for efficient coupling with the coil and ensures smooth rotation. NdFeB Ring Botton Magnet N50 for Iphone Coin Vibrator Motor
Rotor
It is the non-stationary section of the rotational electric motor. The construction and construction between the wires and the magnetic field generate torque. In a few of the constructions, the rotor operates as a motor’s armature, where the input voltage is distributed. N42 Neodymium Coin Magnet fits Precision Micro Drives
Stator
It is the stationary section of the rotational electric motor. It operates like a magnetic field where its contact with armature develops motion. It even functions as an armature that receives force from the motor coils. NdFeB Ring Botton Magnet N50 for Iphone Coin Vibrator Motor
Commutator
It is a rotating electrical switch wherein specific kinds of motors or generators occasionally stores the current flow between the external circuit and the rotor. As it is a switch, it has extended life period, observing the number of circuits creates and collapses which happen in the normal procedure.
Windings
These are the coil turns. All the coils are connected in a way so that it develops a magnetic field when the electricity is passed through these. N52 Neodymium Ring Coin Permanent Magnet fits Precision Motors
Armature
It is the assemblage of two thin metal plates where copper wires are twisted all across the armature’s three poles. Its functionality is to transform magnetic energy to that of kinetic energy.
Brushes
In the shaft, these brushes develop current in between the coils and stator. When the brushes are worn out, motor life also will be ended. So, depending on this aspect, brushless motors which are termed as BLDC are implemented to enhance motor life.
Weight
The shaft is connected with a weighing element so that it generated vibration because of mass. Through this, the pressure and the magnitude can be easily modified and regulated.
Vibrator Motor Specifications/Datasheet
The specifications of vibrator motors depend on the size, weight, operating conditions and many others. Let’s look into the specifications of a few types of vibration motors. For a 10mm shaftless motor with a 3.4mm button type, the specifications are as below.
