FAQ For Coin Vibration Motor
- CW(clockwise) or CCW(contrary clockwise)
1. Gather necessary equipment: multimeter, power source, and connecting wires.
2. Connect the motor to the power source and multimeter in a closed circuit using the appropriate wires.
3. Set up multimeter to measure DC current on a suitable range for the expected current.
4. Activate the by turning on the power source.
5. Observe the multimeter display to read the current flowing through the motor.
6. Repeat with different power inputs or voltage levels if necessary.
7. off the power source, and safely disconnect the circuit. Ensure that all safety precautions are taken into throughout the process.
Small size makes it easy to mount in or on your project. If mounting onto a PCB, there are often options for soldering via through-hole pins. In the case of Coin and LRAs, you can just use the adhesive backing.
General Layout And Operation
Coin vibration motors (also known as ERM motors) generally have a disc-shaped housing made of metal, with a small motor inside that drives an eccentric weight. Here are the general steps of how a coin vibration motor operates:
1. Power On: When power is applied to the motor, an electrical current flows through the coils inside, creating a magnetic field.
2. Attraction Phase: The magnetic field causes the rotor (eccentric weight) to be attracted towards the stator (coil). This attraction phase moves the rotor closer to the magnetic field, building up potential energy.
3. Repulsion Phase: The magnetic field then switches polarity, causing the rotor to be repelled from the stator. This repulsion phase releases the potential energy, causing the rotor to move away from the stator and rotate.
4. Repeat: The ERM motor repeats this attraction and repulsion phase several times per second, causing rapid rotation of the eccentric weight. This rotation creates a vibration that can be felt by the user.
The speed and strength of the vibration can be controlled by varying the voltage or frequency of the electrical signal applied to the motor. Coin vibration motors are commonly used in devices that require haptic feedback, such as smartphones, gaming controllers, and wearables. They can also be used for alert signals, like notifications, alarms, and reminders.
