ENCAPSULATED VIBRATION MOTORS -OVERMOLDABLE VIBRATION MOTORS
Enclosed vibration motors are available with either a plastic capsule made of polystyrene or a metal capsule made of nickel plated steel. Vibration motors that make use our metal capsule design are fully encapsulated and may be over molded. They incorporate a plastic cap at the end of the capsule that is epoxied in place to prevent intrusion of liquids and are water proof. The wires that pass through this cap are epoxied as well. Encapsulated vibrating motors are best suited for applications that require the electronics assembly to be potted, over molded or fully submerged in a liquid. It may also be suitable for applications that require a vibration motor that is intrinsically safe. As of this time, we do not have an IS or IP rating for any of our parts. Models that make use of our plastic capsules may be used in less demanding applications and in most cases may be potted. Encapsulated vibration motors are designed to be overmolded with low temperature / pressure plastics to make them fully watertight, or seal them for use in harsh (e.g. corrosive) environments. All our encapsulated vibration motors are based on a coreless design. It is much easier to fully seal encapsulated vibration motors than other types of vibration motors, due to the lack of external moving parts.
