About products and suppliers:

motor knee (also known as eccentric rotating mass (ERM) or vibrating motors) are motors that use small unbalanced mass to inform users when status has changed. The vibrators provide vibration haptic feedback, and though the vibration is minimal, it provides technical support that helps in improving the electric device humanization.


They are compact sized and shaftless and are perfect for use in non-audible indicators. The most common motor knee are the pager motor and the coin vibration motors, which are both DC motors. These vibrators have a range of applications which include machine handling, use in process industries, and cell phones.


The user can adjust the electrical parameters of the motor, in particular the fanlike eccentric weights installed on both the vibration motors sides can have their angles and centrifugal forces adjusted. Water resistance vibration motors allow custom lead wire connections. There are also options for alternate lead wire length and strip lengths.


There is a wide selection of electrical, pneumatic, and hydraulic motor knee that produce strong vibration at high frequencies. The category includes X-axis coin vibration motors, Z-Axis LRA linear vibration motors or resonant actuators, coreless cylindrical DC motors, and brushless coin vibration motors. Source wholesale motor knee for your business on Alibaba.com and enjoy great deals.
