Linear Vibration Motors

Z-Axis, X-Axis LRA – Linear Resonant Actuators

Excellent choice for light weight wearable devices for precise haptic feedback

---

Need-For-Power Motor  Co., Ltd’s linear oscillating vibrator creates vibration and haptic feedback in Z – direction and X – direction. Precision haptic is generated in Z – Axis linear vibration motor(vibration direction is perpendicular to the LRA’s surface that is different when comparing to rotating mass vibration motor x-y direction). That is suit for wearable applications, more accurate. The special structure of the linear vibrating motors offer high reliability and exceptionally long lifetime. This kind of LRA Motor needs an IC driver such as the TI DRV2603, DRV2605 series. These ICs can provide many waveform library effects built-in vibration patterns for wearable device haptic feedback design, notifications, alerts… You can easily get the haptic motor driver and guide from sparkfun .

3 Key Points To Keep In Mind About Haptic Feedback When Designing Mobile Wearables

---

1. The layout of the LRA motor is very important. Generally, it should be placed at the bottom of the mobile devices. The diagonal line has the strongest vibration, so try to avoid stress-sensitive devices on the diagonal line. The camera module should also avoid abnormalities caused by driving the module. ring.
2. The motor signal is relatively dirty, pay attention to the protection of the ground and the signal, and keep away from sensitive signals.
3. In the early stage of design, the vibration of the motor should be simulated.

They are typically used in applications where a linear vibrational force is required, such as in vibrating conveyors and screens. Linear vibration motors typically have a rectangular or cylindrical shape. Linear vibration motors are typically more efficient than other types of vibration motors. Linear vibration motors are used in a variety of applications, including vibrating conveyors, vibrating screens, and vibrating feeders.

If you’re going to use highly responsive vibration motors such as LRA to convey complex information to users by vibration, you need to have the experience of challenges, regulations & risks you will face. First step suggest you buy the haptic feedback/development kit from Texas Instruments, so you can simulate & test different alert styles.

TI’s haptic feedback kit Includes Haptics/Vibration Motor Experiments & Creates more than 100 kind of effects. You can do the experiment with different haptic feedback effects to enhance your product. At the same time you can find a way on Haptics and learn how to add it to your next project.

X-Axis 15mm x 8mm x 3mm Linear Motor Haptic Feedback Sensor

Our X-Axis rectangular LRA motor have many surprise to the end customers, it is the largest and most powerful X-axis (horizontal) linear vibration motor for wearable devices. As shown by its data, the motor has a vibration amplitude increase of 200%, driving power increase of 400% and distortion decrease 90% when compared with the traditional motors.

NFP’s rectangular LRA model NFP-ELV1411A have an internal mass that oscillates back and forth along the X-axis at it’s resonance frequency. And the pancake (coin) type linear resonant actuators oscillates ups and downs along the Z axis, perpendicular to the motors surface. Both the rectangular and the coin type LRAs are driven by the TI’s LRA driver DRV2605L – ICs or other driving ICs, that’s another difference between ERM and the LRA. Fast feedback vibration motor, Z direction – axis vibration motor. Fast response and vibrant strength to deliver a vivid haptics experience. Haptics solution, Path to completely buttonless devices. User interaction through touch screen or side sensors with high performance customizable haptic feedback. Richer haptics feedback synchronizes with the audio and visual effects providing striking immersive experience.

Adjustable Vibration Motor Linear Typical Applications

Smartwatches, Smart rings, Hi-Rel devices, Medical devices, Lightweight wearable devices, Haptic feedback devices, Touch screens, Wearable devices, Any lightweight device requiring a silent alert or haptic feedback, such as Haptic Vest VR, 3D Printer, Vibration actuator device.

Due to lack of physical buttons, vibration is required to simulate the real touch, the improvement of interaction experience such as playing games, typing keyboard those need to be remind by vibration. Once end customer experience haptic feedback will show special favor to it.

In the early times, cell phone or pager used traditional eccentric rotating mass vibration motor which creates vibration by driving a mass to rotate randomly. It’s a rough vibration alert. Advantage is low cost. However it doesn’t have a quick start nor break time. Just a rough vibration sense and super poor human experience. That’s why vibration motors have not been better used in various touch scenarios.

A good haptic vibrator request suit IC chip to drive. That means a full-scene deep vibration optimization. Educated souls means to match the motor vibration frequency with the musicality and rhythm of different ringing music to realize musical vibration. The excellent experience of X-Axis vibration motor even changed people’s attitude towards wearable devices.

The foreseeable future is that vibration feedback will have more advanced technologies and functions in the future. Haptic motor should be able to help touch screens realize true buttonless full display and outperform the physical buttons in the interaction experience, in addition to becoming more powerful, smaller and more intelligent. It will soon become a reality, according to the current progress.

Main features: Lower power consumption | High reliability driven by IC | Rated current: 80mA | Typical rated: 5mA to 80mA | Resonant frequency: 220 Hz – 240Hz | Rated voltage: 2.0 VAC – RMS | Working voltage 0.1 ~ 2.0 VAC -RMS

Main features is fast rise and fall times and superior braking ability. Their relatively simple internal construction offers high reliability and exceptionally long life when compared with brushed ERM motors. Need-For-Power Motor  Co., Ltd’s LRA have an internal mass that oscillates back and forth along the X-axis at its resonant frequency. They are an excellent alternative to brushless vibration motors as the only internal parts that are subjected to wear / failure are the springs.

We offer significant vibration motor customizations to our customers around the world. More than 100 kinds of vibration patterns precise haptic feedback effects to experiment with when creating tactile touchscreens. Find a way to turn your complex haptics &mini motor problems into simple solutions. Upgrade your application or product with precise Haptic Feedback effects.

Later time, based on the high level universal platform for electromagnetic technology and the development of Z-Axis (vertical LRA which can provide precise response and various vibration patterns) linear vibration motors. The X-Axis haptic vibration motor came out. It is the most advanced X-Axis (horizontal) linear motor in the world, featuring the best sense of strength, the lowest latency and the most delicate and diverse feedback. Its touch feels more like physical buttons, and you will have the impression that you can truly press it. While eliminating the shaking effect, the motor can produce multi-level vibration sense through teaching. This means that when the consumers type or play games, they can precisely feel the vibration pressed by their fingers, and the vibration strength will change according to the pressing force.
