PCBMOTOR Design example The core element of an application is the stator (Fig 1). This part can be supplied by PCBmotor in various diameters currently ranging from 20 mm to 90 mm our webpage. The example used in this article uses a jigsaw has an outer diameter of 30 mm and an inner diameter of 22 mm. The stator is built on a 1.6 mm PCB (FR4) and has 48 piezo elements on each side. Stator thickness is 2.6 mm total. Typical mechanical performance will yield approx. 40 RPM and stall torque approx. 18 Nmm. The rotor consists of two discs placed on each side of the stator. Both discs have friction tape where they will rest on top of the piezo elemen To obtain a controlled pressure of the rotors towards the stator, one of the rotors has a center spring which will ensure an even distributed force and allow for planetary and dimensional tolerances of the stator. At the same time the spring must be or you can download PCB layouts from ss elements. able to transfer the torque from the
