We recently made the following test setup for one of our customers who required a ‘loaded’ motor to perform a specific rotational sequence. The motor used for the test is our 30mm PCBMotor w/100-Line Encoder – modified with a 400-line encoder. The test result was that the 30mm diameter motor with a load of 230g easily […]
New 60mm Stator design Improved design version now delivers up 110Nmm stall for Ø60mm stator with 6N pretension and 5V supply, see newest motors characteristic here. A calibrated torque-cell with an electrical brake and a load cell to measure pre-tension. This allows us to measure the complete torque/speed curve down to stall at different […]
Driver two motors with same driver It is fine to drive two motors in parallel on the same output stage as long as they have the same resonance frequency. So if you use motors (same size) and from the same batch and you should be ok, since the frequencies are very close. Motor produced on […]

PCBMotors consist of two parts: The Stator, which holds the actuators and electrical connecting circuit; and The Rotor, which is pressed onto the surface of the stator and delivers the mechanical output. A traveling wave is generated over the stator surface, acting like a flexible ring to produce elliptical motion on the rotor interface. The […]
By driving the integration of the motor (including electronics) into the PCB itself, we’re facilitating the design of smaller, cheaper and faster applications. PCBMotor uses less space and material. Electronics (driver) and mechanics (motor) are mounted directly on the PCB – so it’s totally flat and without gears and connections. PCB enables more design flexibility […]
Our technology is patented. We, obviously, want to spread the use of this new technology and will earn our investment by being the sole supplier of piezo components used in PCBMotors.
You can improve your market position by offering your customers state of the art technology/applications AND save them money at the same time. Offer your customers faster, smaller and cheaper motors. That’s because of the innovative design of the PCBMotor: Mounted directly on the PCB – the motor and all electronics (driver) are integrated into […]
The piezos generate the vibrations, a traveling wave, on the stator which makes the rotor turn. The stator needs to be able to vibrate freely for this traveling wave to exist.
No, the rotor is a part of the individual customer’s application and, therefore, not part of our delivery.
Yes. PCBMotor can provide you with training and help you to design and build your own PCBMotors. We can also provide schematic for the control driver (free of charge), which you then can build on your own. See our Steps to Success.
Yes. PCBMotor can design and manufacture an entire PCBMotor solution – comprising stator, driver and positioning system – all designed specifically for your application. See our Steps to Success and how we can accelerate your product’s time-to-market.

It is the friction between piezo elements and rotor that translates the traveling wave on stator into a rotational force on rotor. To ensure sufficient friction a friction tape is mounted on rotor. We’ve had good experience and results using H-old: GL.96.glass fiber enforced adhesive tape with an alu layer. Apart from ensuring the required […]
No, you will be able to turn the rotor without damaging anything. If the positioning system power is still ‘On’, the positioning system will keep track of its position. This can be used in, for example, a sound mixing console allowing a PCBMotor-operated control to be set to a specific setting and adjusted manually to […]
No, the rotors are preloaded by springs pressing them against the piezo elements. This results in a holding torque whether the power is on or off. The holding torque is about 2-3x the stall torque. Being able to turn motor power off when not rotating can, in some applications, prove to be a very important […]
With no load on the rotor the start/stop time is less than 1 ms. With load on rotors the start and stop time will of course increase.
The rotors are preloaded by springs pressing them against the stator ensuring stable contact between piezos and rotor. The spring force is set for optimum motor performance. A load of 100-200 grams on the rotor or the axle will have little or no effect on performance. Heavier objects should be mounted directly onto the axle […]
A PCBMotor has no inherent, mechanically-defined step size. It will rotate with a constant speed of around 1 revolution per sec is requiredond as long as power is applied. To establish and use stepping functionality, a positioning system, see section “Positioning System”.
