Piezo Assist Motor *
Piezo Assist Motor(PAM3-6.5 and PAM6-13)
- Assist Motor is compact in size, and designed to have a high output force up to around 13N for PAM3-6.5 and around 29N for PAM6-13.
- The output displacement is 6.5mm for PAM3-6.5 and 13mm for PAM6-13. The high displacement resolution is below 25nm~30nm while the travel velocity is above 1.5m/s.
- The Piezo Assist Motor is designed user friendly for industrial, scientific research applications.
- Applications include Microscope scanning, High resolution microscope, Biotechnology, Measurement technology, High speed throughput microscope, Mask/ Wafer positioning, Interferometer shape measurement and Micromanipulation.
- Please use the designated Piezo Assist Motor Controller (PAMC-104)to drive the Piezo Assist Motor. A software and cable (2m) is attached to Piezo Assist Motor.

Piezo Assist Motor Operating Principal
Piezo assist motor rotates based on the inertial rotation mechanism inside the housing. This generates thrust and displacement in the direction of the screw shaft. As shown in Fig. 2, the inertial rotation mechanism principal diagram, the screw shaft work as a rotor. The screw shaft is connected to the moment of inertia (rotary knob, etc.). The screw shaft is hold by the contactor with stat-ic friction force. Therefore, no power consumption is needed to maintain the po-sition. When the piezoelectric actuator extends as shown in Fig. 2, contacts A and B move at an opposite direction to each other. An acceleration at contact A and B is created intentionally. The acceleration will take over the static fric-tion and generate a slippage between rotor and contact. The slippage resulted a rotational motion of the screw shaft. As a result, the screw shaft is moved in a thrust direction.

Piezo Assist Motor Operation Example
Fig.1 and Fig.2 show the displacement vs characteristics of the Piezo Assist Motor driven at 40 pulses with
drive frequencies of 1Hz and 5Hz. Fig.1 shows the data during forward
rotation, and Fig.2 shows data during
reverse rotation
- At 1Hz, the displacement is stepped at 10~16nm/pulse, and the displacement is smooth at 5Hz.
- The displacement for 40pulses is 480nm (average 12nm/pulse) in forward rotation for both 1Hz and 5Hz. They are 520nm(average 13nm/pulse) in reverse rotation.
Application example of Piezo Assist Mirror (Angle Adjustment of Mirror Holder )
- Ultra-fine resolution in Nanometer
- Holds position even when power is not supplied
- Movable angle range is ±3.5°(≒ ± 61mrad )
- 1.6 μrad Ultra-precise adjustment by ( Over 70,000 steps)
