PCBMotor develops new technology for movement in applications

Today’s challenge is making electronic applications smaller and cheaper. A patented new technology now enables you to build accurate and powerful motors directly onto the PCB itself. Henrik Staehr-Olsen, CEO of PCBMotor, the Danish company behind the technology, explains: “Traditional design methods use PCBs as motor controllers with connections to a physical motor located somewhere in the vicinity of the card.  Our technology builds one or more motors directly onto the PCB itself. This significantly reduces application costs and introduces a world of new design opportunities.”

Are these challenges relevant to you?

  • Do you have an electronic application that requires movement?
  • Would you like to integrate several motors directly onto a single printed circuit board?
  • Do you need precise control of a lens, valve, laser, mirror, pointer or similar?
  • Do you need to automatically and manually adjust a button/switch without it being damaged?
  • Would you like to reduce the height of your application?

A PCBMotor offers an innovative way to increase your profit margin using standardized components and well-established assembly techniques that:

  • Make your application(s) smaller by integrating motion and all electronics onto one printed circuit board
  • Reduce your bill of materials: PCBMotor’s direct drive eliminates the need for gears and piezo components are SMD-mounted directly on the PCB, so there’s no need for screws, wires, connectors and manual assembly
  • Innovate using the unique and ultra-slim form factor of the PCBMotor

Under the hood of the on-board PCBMotor
Technically speaking, the PCBMotor consists of two parts:

  1. The stator. Milled out of the PCB itself, houses the piezos/actuators and the electrical connecting circuit (the PCB can also hold the driver)
  2. The rotor. Pressed onto the surface of the stator, which delivers the mechanical output. 

A travelling wave is generated over the stator surface, acting as a flexible ring, and produces an elliptical motion on the rotor interface. This elliptical motion of the contact surface propels the rotor and the connected drive-shaft.

1 mm x 1 mm piezo ceramic components are mounted on PCB. Operation depends on friction between the moving rotor and the stator as well as the amplitude and quality of the wave travelling on the stator. The rotor can turn between 60 and 120 RPM with torque ranging from 1 Nmm to more than 70 Nmm depending on the stator’s diameter, the number of piezo components and the rotor design and material.
