Energy Efficency

The traditional motor system cannot meet parameters such as high resolution (nanometer level), stiffness, zero backlash, short response time etc., all of which are key parameters for a nano-positioning system. Traditional drives also require power to be permanently switched on to hold position and minimize backlash problems. Their response time is relatively long and the…

piezo motor technology

Fundamentals

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…

non magnetic piezo motor

Non-Magnetic

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…
