To see our application design examples and layout possibilities, check out our Google+ albums  - and don't worry, you don't have to be signed up or logged in.
 

We moved all our design examples here for a variety of reasons, but mainly for your (and our) convenience and because it's such a great way to view and maintain our expanding database of design images.

So take a look and feel free to comment or drop us a line if you've any questions.

Hollow-shaft designs (Video)

Check out our Youtube channel for more videos about our technology and discover how our hollow-shaft designs and ultra-high resolution motors can reduce your bill of materials and fast-track your end-product's time to market.

Stator

The core element of an application is the stator (see figure 1 above). This part can be supplied by PCBMotor, in various diameters currently ranging from 20 mm to 90 mm, or you can download PCB layouts from our website. 
The stator is 2.6 mm in height and built on a 1.6 mm PCB (FR4) with piezo elements on each side. Typical mechanical performance yields approximately 40 RPM and a stall torque of 18 Nmm.

Rotor

The rotor consists of two discs placed on either side of the stator. Both discs have friction tape where they will rest on top of the piezo elements. To obtain a controlled pressure of the rotors towards the stator, one of the rotors has a center spring which ensures an evenly distributed force and allows for planetary and dimensional tolerances of the stator. 

Motherboard

The motherboard has two functions. Firstly, it provides the electrical connections to the motor (Sin, Cos and Gnd). Secondly, it has a bearing to keep the rotor in the center position.

Is your application PCBMotor-ready?
