    - Piezo LEGS® Technology

    The word “piezo” is derived from the Greek word for pressure. In 1880 Jacques and Pierre Curie discovered that pressure generates electrical charges in a number of crystals such as quartz and tourmaline; they called this phenomenon the “piezoelectric effect”. Later they noticed that electrical fields can deform piezoelectric materials. This effect is called the “inver...

    - Piezo LEGS® Technology

    Piezo LEGS® motors don’t have the windings of a DC motor and will not be a source of magnetic flux. Standard housing material is stainless steel, so the body of the motor will be ferritic by nature and will disturb an external magnetic field. Completely non-magnetic motors are also available, where motor housing and other parts are made from non-magnetic alloys. Motors of that kind will be compati...

    - Piezo LEGS® Technology

    By applying voltage to a piezoelectric material, you can make it change its shape. Through the clever design of the Piezo LEGS® ceramic actuators, each of the motor “legs” can be elongated as well as bent sideways. With appropriate drive signals, you can create synchronized movement of each pair of its four legs, and it will begin to walk just like an animal would – step by step, and stopping at a...

  • PiezoMotor launches new compact and strong precision motor

    - Product Releases

    PiezoMotor is proud to announce the release of a new direct drive linear motor with integrated encoder, Piezo LEGS® Linear 6N, also called LL06. PiezoMotor has developed the next generation of its classic Piezo LEGS®. The motor has undergone major redesign and repackaging, with the same piezo ceramic actuators at its core as the predecessor LL10. The basic performance characteristics are therefore...

  • High Precision

    - Piezo LEGS® Technology

    The demand for higher accuracy in manufacturing is driving the development of precision machinery and measuring tools. Analytical instruments and manipulators in the medical sector are advancing and getting more exact. The semiconductor industry is continuously working with higher precision instruments to scale down devices on the silicon wafer. Wherever there’s a demand for the highest precision,...
