Encapsulated vs Enclosed Vibration Motors

Protecting the eccentric mass of a vibration motor is essential to its operation.

Although some achieve this through mounting methods, such as press-fit moulding products, there are also motor types that protect the eccentric mass with an enclosure. The most obvious of these is the coin motor, but due to their form factor, they are limited in strength.

Instead ‘enclosed’ and ‘encapsulated’ motors are in the cylindrical form and can offer higher vibration amplitudes. Here we clear up the difference between an enclosed motor and an encapsulated motor.

What Does “Enclosed” Mean?

Enclosed motors have no external moving parts, but include screw holes in the casing. These are great for mounting the units to bulkheads and sheets of metal, found in the Uni Vibe™ range their higher amplitude means they are ideal for mechanical aid applications.

It does mean that although the screw holes are intended to be populated, the casing is not fully sealed. The hole sizes and positions are outlined in the Dimensional Specifications section of the datasheets. More information on the available products below:

What Does “Encapsulated” Mean?

Encapsulated vibration motors also have no external moving parts, but are sealed units. This helps solve a variety of mounting issues and as a result, the 307-100 (since depreciated) is very popular for prototyping.

We have suggested using them in body-worn haptics and other applications, but they’re also suitable for any uses that the Pico Vibe™ may be used for.
