Piezo LEGS® Linear Twin-C 40N Direct drive - backlash free Nanometer resolution Quick response Optical mount interface The Piezo LEGS 40 N linear motor is intended for use in a large range of applications; laser and optics applications, moving mirror mounts, replacement for micrometer screws etc. The very high speed dynamics and nanometer resolution makes it ideal for numerous applications. The LEGS technology is characterized by its outstanding precision. Fast speed and quick response time, as well as long service life are other benefits. In combination with the nanometer resolution the technology is quite unique. The motor is ideally suited for move and hold applications or for automatic adjustments. When the motor is in hold position it does not consume any power. The drive technology is direct, meaning no gears or lead screws are needed to create linear motion. This means the motor has no mechanical play or backlash. The LTC40 linear motor is available with a few different mounting options - clamp, nut, or flange. Operating modes The motor can move in full steps (wfm-steps), or partial steps (microsteps) giving positioning resolution in the nanometer range. Speed is adjustable from single microsteps per second up to max specified. PiezoMotor offers a range of drivers and controllers. The most basic one is a handheld push button driver. Another option is an analogue driver that regulates the motor speed by means of an ±7 V analogue interface. One of the more advanced alternatives is the PMD101 Microstep Driver/Controller. This product enables the user to vary the waveform as well as speed. The PMD101 is equipped with encoder signal inputs for close loop control. The microstepping feature divides full step cycle into maximum 2048 increments which results in microsteps as small as two nanometers. Design your own driver Some customers prefer to design their own driver for ease of integration or for even higher waveform resolution (subnanometer range). In this case PiezoMotor can provide information to assist in the design.

Piezo LEGS® Linear Twin-C 40N 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...

Piezo LEGS® Linear Twin-C 40N Note: Refer to drawings for details. Drive shaft has only limited bending moment capability, and absolutely no rotational torque is allowed. In order to safely mount an endpiece in the threaded hole, you must first release the motor completely (it must not be fixed in position). Thereafter, hold on only to the flat part of the shaft and fasten endpiece tightly.
