Vibration Motors

This series of surface mount vibration motors, with spring contacts, make an excellent choice for a variety of reasons. Unlike our SMT Reflow motors, these motors are NOT designed to be soldered to the PCB. The contact springs on these motors simply mate with contact pads on the PCB. This type of motor offers some distinct advantages as follows:


Lower Cost:This series of motors are approx. 10% lower in cost than SMT reflow vibration motors.

Efficient Vibration Energy Transfer: These motors can be mounted in the plastic case of a products housing where it is more likely to be felt and less likely to be dampened like motors that are mounted on a PCB.

Increased Reliability: Vibration has been known to contribute to product failures. Minimizing the amount of such energy transfer to the PCB can only be helpful in this regard.

Superior Serviceability: In applications where the motor is subjected to extreme duty cycles, that exceed the motors rated life, premature motor failure may occur. Replacing this type of vibrator motor, even in the field, is fast and efficient as no soldering in required to remove and replace it. (continued below)

The spring contacts of these vibration motors are not designed to be soldered to. A downward force must but be applied to the top of the motors body to compress the spring contacts directly against corresponding PCB contact pads. It is recommended that these pads be gold plated to improve reliability. Some recommended motor mounting options include, fabricating a silicone rubber pad with a cut out for the motor which will properly locate the motor directly above the PCB pads. Recesses are designed under the pad to accommodate the profiles of all the other parts that lie beneath it. When the product housing is closed, it will exert a downward pressure on the vibrator motor ensuring properly spring compression and electrical contact. Alternately, a pocket may be created in the plastic cover (shell) of the products housing to hold the motor. The motor are mounted in a silicone rubber boot that helps retain the motor in the pocket and helps dampen high frequency harmonics. When the cover is closed, the contacts mate with corresponding pads on the PCB.   CLICK HERE  to see photos of motors mounted in devices.
