Piezo LEGS Linear Twin-C 450N ® Direct drive – backlash free Nanometer resolution No power draw in hold position Quick response Heavy loads The LTC450 motor is intended for high force and precision applications. This includes applications in vacuum for the semiconductor industry. The advantage of using the Piezo LEGS technology is the very precise positioning resolution, as well as automatic locking giving true setand-forget performance. The technology is based on direct drive without any backlash. The Piezo LEGS technology is characterized by its outstanding precision. Quick response time, as well as long service life are other benefits. In combination with the nanometer or even sub-nanometer resolution the technology is quite unique. PiezoMotor offers a range of drivers and controllers. The more advanced alternatives are the microstep drivers/ controllers in the 100- and 200-series. These products allow for closed loop control and precise positioning. The microstepping feature divides the wfm-step into thousands of small increments which results in microsteps in the nanometer range. The PMD units are straight forward to use, supports quadrature and serial sensors, and have multiple I/O ports. Design your own driver Some customers prefer to design their own driver for ease of integration. In this case PiezoMotor can provide information to assist in the design. Operating modes The motor can move in full steps (waveform-steps), or partial steps (microsteps) giving positioning resolution in the nanometer range. Speed is adjustable from single microsteps per second up to max specified. Ordering information Motor LTC45011-020 Linear Encoders See separerate data sheet

Piezo LEGS Linear Twin-C 450N ® Operating Principle 1 When all four legs are electrically activated they are elongated and bending. As we shall see below, alternate legs move as pairs. Arrows show the direction of motion of the tip of each leg. The Piezo LEGS walking principle is of the non-resonant type, i.e. the position of the drive legs is known at any given moment. This assures very good control of the motion over the whole speed range. The performance of a Piezo LEGS motor is different from that of a DC or stepper motor in several aspects. A Piezo LEGS motor is friction based, meaning...
