which vibration motor have the longest lifetime?

 

Life for phone motor

Usually,we use BLDC motor,coin motor ,smt motor and LRA motor for smart phone.

 

And follow is the lifetime for these motors:

Under the condition  On 1sec/Off 1sec .

 

The life for as follows show:

 

BLDC Motor	Coin Motor	SMT Motor	LRA  Motor
2000,000 cycles	100,000 cycles	200,000 cycles	1,000,000 cycles

We can find that BLDC motor can have more than 1000 hours for life time.

This is very nice for urability.

And BLDC motor is widely used in new model.

LRA motor is also very nice. 

 

When the motor used in smart phone.

The service life of mobile phone vibration motors is influenced by various factors, including temperature, humidity, voltage, load, etc. 

If these factors cannot be effectively controlled, the service life of the vibration motor will be affected and even damaged in advance.

Therefore, in order to extend the service life of the vibration motor on  phones, we should take the following measures:

1. Control environmental temperature and humidity: Temperature and humidity are important factors that affect the service life of the vibration motor. Therefore, we should try to maintain the environmental temperature and humidity within the normal range to ensure the normal use of the vibration motor. 

 

2. Control voltage: If the voltage is too high or too low, it will affect the service life of the vibration motor. Therefore, it is necessary to try to keep the voltage within the normal range to ensure the normal use of the vibration motor.

3. Load control: Excessive load can cause overheating of the vibration motor, thereby shortening its service life. Therefore, it is necessary to control the load as much as possible to ensure the normal use of the vibration motor. 

 

4. Regular inspection: The working status of the vibration motor should be regularly checked, and problems should be identified and dealt with in a timely manner to ensure the normal use of the vibration motor. In short, in order to extend the service life of the vibration motor on Apple phones, effective measures must be taken to control environmental temperature and humidity, control voltage, control load, and conduct regular inspections to ensure the normal use of the vibration motor.

What's the differ between X-axis and Z -axis linear motor

There are the following differences between X-axis linear motors and Z-axis linear motors in mobile phones:

Different directions: X-axis linear motors and Z-axis linear motors move in different directions. The X-axis linear motor can move in the horizontal direction, while the Z-axis linear motor can move in the vertical direction.

Different functions: Due to different directions, the functions of the X-axis linear motor and the Z-axis linear motor are also different.

The X-axis linear motor is mainly used to provide vibration feedback in the horizontal direction. It can generate corresponding vibrations when users slide the screen, operate games, or touch buttons, enhancing the user's tactile experience. For example, when playing games, the X-axis linear motor can simulate different tactile feedback, such as strikes, impacts, or vibrations, making users more immersive. In addition, when sliding the interface, the X-axis linear motor can provide a physical sense of sliding through weak vibration feedback, increasing the interactivity of the interface.

The Z-axis linear motor is mainly used to provide vertical vibration feedback. It can generate a sense of vibration when notified of an arrival, when a button is pressed, or when a specific event is triggered. For example, when receiving messages or incoming calls, the Z-axis linear motor can alert users through vibration, allowing them to sense important notifications even without looking at the screen. In addition, the Z-axis linear motor can also provide the physical touch of buttons when touching them, enhancing the user's button experience.

Different sizes: Due to different directions and functional requirements, the sizes of X-axis linear motors and Z-axis linear motors also differ. Typically, X-axis linear motors may have smaller dimensions, while Z-axis motors may require larger dimensions to provide sufficient force and accuracy.

In summary, there are significant differences in direction, function, and size between X-axis linear motors and Z-axis linear motors, so they are typically used in different application scenarios.

Which type of linear motor is better depends on the specific usage scenario and requirements. The X-axis linear motor and Z-axis linear motor have functional differences, but both can provide a good tactile feedback experience. The choice of which linear motor is better depends on the user's personal preferences for tactile feedback and specific usage scenarios. The following are the characteristics and applicable scenarios of X-axis linear motors and Z-axis linear motors:

1. X-axis linear motor: The installation position of the X-axis linear motor in the mobile phone is on the left and right sides, mainly used to provide horizontal tactile feedback. The following are the characteristics and application scenarios of X-axis linear motors:

(1) Game experience: X-axis linear motors can simulate tactile feedback in games, such as hitting, hitting, or vibrating sensations, enhancing the immersion and realism of the game.

(2) Sliding interface: When sliding the screen or browsing applications, the X-axis linear motor can provide weak vibration feedback, increasing the interactivity and tactile experience of the interface.

(3) Operation feedback: When the user operates the physical or touch buttons of the phone, the X-axis linear motor can provide tactile feedback, allowing the user to perceive the actual tactile operation of the buttons.

1. Z-axis linear motor: The Z-axis linear motor is installed on both sides of the phone, mainly used to provide vertical tactile feedback. The following are the characteristics and application scenarios of Z-axis linear motors:

(1) Notification reminder: Z-axis linear motors can alert users to receive new messages, incoming calls, or other important notifications through vibration, even without looking at the screen.

(2) Physical button simulation: When touching virtual buttons or areas on the screen, the Z-axis linear motor can provide tactile feedback of physical buttons, allowing users to have a more realistic button experience.

(3) Vibration feedback: Z-axis linear motors can generate vibration feedback in specific application scenarios or trigger specific events, such as explosive effects or emphasis prompts in games.

In summary, both X-axis linear motors and Z-axis linear motors have their own advantages and usage scenarios in providing tactile feedback. Choosing which linear motor is better depends on the user's personal preferences and specific usage needs. If you focus more on the gaming experience, interactive sliding interface, and operational feedback, then the X-axis linear motor may be more suitable for you. If you value notification reminders, physical button simulation, and vibration feedback more, then the Z-axis linear motor may be more in line with your needs. However, in terms of the current level of use on the market, the X-axis linear motor is more widely used.
