Piezo LEGS® Rotary 50 mNm • • • • • Non-magnetic Direct drive - backlash free Microradian resolution No power draw in hold position Quick response The Piezo LEGS Rotary 50mNm motor is non-magnetic. It is intended for a large range of applications where there is demand for non-magnetic material in motor. The very high speed dynamics and micro radian precision makes it ideal for numerous applications. High torque output in a small package is also beneficial. 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 micro radian 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 are needed to create motion. This means the motor has no mechanical play or backlash. The Piezo LEGS 50 mNm non-magnetic motor is available in a standard version, and in a vacuum version. Operating modes The motor can move in full steps (wfm-steps), or partial steps (microsteps) giving positioning resolution in the microradian range. Speed is adjustable from microsteps per second up to max specified. Controlling the motor 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 ~0.5 microradians. PMD101 Design your own driver Some customers prefer to design their own driver control for ease of integration or for even higher waveform resolution. In this case PiezoMotor can provide information to assist in the design.

Piezo LEGS® Rotary 50mNm Operating Principle 1 When all 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 the motion...
