JiFei Holding Limited would like to  introduce a micro-sized PCB-mounted vibrator motor https://www.vibrationmotor.net/pcb-mounted-vibrator-motor/ which based on a surface-mount form factor, and suitable for use in many handheld appliances and instruments to u.

This SMD vibration motor can be reflow soldered and comes on tape and reel for quick and efficient pick-and-place assembly.

A new addition to Jifei’s range of Pico Haptic miniature vibrating motors, it offers a tiny PCB footprint and an efficient mass-assembly method.

Micro-sized vibrator motors such as the 304-109 are used in many handheld appliances and instruments where there is a requirement to alert operators and users that an event has occurred.

Termed ‘operator/user alerting’, the vibrator motor has much the same function as an LED, lamp, buzzer or audio alarm.

The benefit of using vibration motors in this way, and vibration-tactile feedback in general (also known as haptic feedback), is that it works in scenarios in which users can’t see or hear the device.

The silent profile in cell phones and pagers is an example of where vibration tactile feedback warns users in a wide range of situations, no matter where the device is actually located.

Jifei  produces a wide range of vibrator motor form factors in miniature scales from 4mm through to 12mm motors that are easy to integrate into designs.

Jifei’s range offers PCB-mounted vibrating motors, including spring and pad vibration motors, reflow surface-mount motors and thru-hole pin and flying-lead vibration motors.

We also produces self-adhesive mounting coin vibration motors, as well as motors designed with rubber surrounds for easy mounting within enclosures.

The 304-109 surface mount vibrator motor has an external footprint of 4.5mm wide, 13.6mm long and 4.5mm high and weighs in at 0.95g.

This 4mm coreless cylinder motor is based on the same proven technology as the other 4mm, 6mm and 7mm types offered in the Pico Haptic range of micro vibration motors.

The SMD vibrator motor, rated at 3V DC, runs at a nominal 12,000 RPM (200 Hz) while generating 0.6g (5.88m/s) of vibration.

Based on a coreless three-pole design, the motor has a certified start voltage of 1.4V.

Typical current draw is 70mA and the motor has a typical vibration efficiency of 2.7g/W.

With a typical noise output of 50dBA, the motor is quiet for vibration standards and has a standard operating temperature of -20C to 60C, though these can be extended by request.

The motor comes via either cut-tape or as standard package size of 1,000 pcs on a 330mm reel.

This vibration motor is designed for pick-and-place and reflow RoHS-compliant soldering processes.

Coin Vibration Motor Failure Analysis

Coin Vibration Motor Failure Analysis

Problem:

When the motor is installed, the vibration failure and not vibrating.

Analysis:

1.Recheck and confirm:
The performance review found that feedback motor have the rotor wire breaking phenomenon (i.e. rotor two coils with a hard line OK, another hard coil and open circuit phenomenon)which determine the performance of motor NG.

2.Disassemble inspection: (Main motor parts:up case,down case, rotor)
Disassemble the motor and inspect the rotor circuit:
1 feedback motor rotor testing (P1) into a 37 ohm resistance line detection OK (P2), the two resistor resistor of 4.7, coil and hard line disconnection (P3)

 


        P1                          P2                          P3

Summary: 

Through the analysis of the performance inspection and disassemble, analysis personnel to determine the rotor broken is the result of motor performance when vibration is not the main vibration

Reason analysis:

1, the cause of poor motor working principle of vibrating motor is energized by current due to contact between brush and commutator of the current flowing into the coil, coil and stator magnet formed cut magnetic lines, so as to generate electromagnetic force, the electromagnetic force of the rotor rotor. A feedback coil motor rotor is broken, another coil line OK, the motor will appear when the brush and the commutator coil is connected with a good connection when the motor vibration, when the brush and the commutator coil wire connection motor vibration phenomenon. When the motor vibration is caused by vibration.
2, causing the rotor broken motor outflow reason: our resistance of the rotor is full inspection, the rotor does not exist disconnection normally under the stream, in addition to the motor rotor assembly after our performance and semi-finished products and finished products inspection inspection process, the motor will not break the phenomenon of outflow will exist. Analysts believe that the feedback motor thread breakage is due to coil coil welding welding workers, no coil and H-PCB coil with H-PC welding, weld phenomenon, cause the motor in operation after a period of time, a coil and a H-PCB connecting line. In the inspection personnel to check the motor, when the coil is connected with the brush and the commutator good connection, motor vibration, when the brush and the commutator coil connection is disconnected, the motor vibration and vibration when the motor is bad, no vibration phenomenon.

Improvement measures:

1, to strengthen staff training and education of the rotor coil, avoid the defects of weld, welding sparks coil.
2, strengthen the training and education of motor performance testing personnel, while strengthening the supervision of motor performance testing process, to avoid false detection, omission phenomenon.

Haptic Feedback Motor

Haptic motor

Haptic feedback motor is a kind of intelligent vibration motor, according to different application scenarios, allowing users to feel a different sense of shock, and can subtly produce different subtle vibrations in different position on the touch screen. The haptic feedback motor allows the user to interact with the electronic products in a more in-depth manner, simulating a more comprehensive virtual environment

FEATURES

• More vibration effects.
• Facilitate the process of prototyping.
• Easy-to-use library with 123 kinds of vibrating modes.
• Powerful driver to implant more advanced functions.

APPLICATIONS

• Mobile phones and tablets.
• Wearable devices.
• Remote controls, touch-enabled devices.
• Industrial human-machine interfaces.

The difference between a linear motor to a bar motor or coin type motor

The difference between a linear motor to a bar motor or coin type motor

At first, the smart mobile phone is mainly used to provide feedback to the user's voice, and later with the mobile phone software is more and more abundant, the user experience on the use of increasingly high demand, use sound to provide feedback has been unable to meet the demand of users of intelligent mobile phone. As a result, part of the smart phone began to use the motor to provide vibration and touch, but with the increasingly thin cell phone, the traditional rotor motor can no longer meet the new requirements, so the linear motor came into being.

And what's the difference between a linear motor and a tradtional bar motor and coin type motor.

Pls refer to as follows:

We can find that the linear motor can make the user feel different vibration sensation according to the different scene, and can send out different subtle vibration on different positions of the touch screen.

And long life time but little current consumption.

It will be the best choose for smart phone.
