Auburn, MA – Physik Instrumente’s (PI) patented P-653 piezomotor linear slide is significantly smaller than other miniature linear stages and provides significantly higher velocities and resolution. It features a travel range of 2mm with force generation to 0.15N and comes pre-assembled and mounted on a PC board and is only 8mm long.
This true linear motor system has no conversion of rotation, eliminating rotary conversion losses, and consists of only 4 parts and can replace classical drive elements like miniaturized motor/lead screw systems or other linear motors with speeds of up to 200mm/sec (8in./sec) and an auto-locking feature. Integration of the P-653 is simple because the moving slider and the piezomotor are delivered assembled as a unit on a PCB driver board running on 5VDC.
P-653-series PILine® ultrasonic motors are ideal for OEM applications where quantities are high and space is at a premium. The systems are optimized for moving small objects such as optical fibers, micro-optics, or micro-electromechanical elements fast and precisely. These non-magnetic ceramic motors can also be used in medical applications.
Motion is controlled by TTL voltage pulses applied to the driver electronics. The self-adjusting driver creates the high-frequency, nanometer level oscillations (~500kHz) that make the ultrasonic ceramic motor move. PILine® linear piezomotors are based on a patented ultrasonic drive. At the heart of the system is a rectangular monolithic piezoceramic plate (the stator), segmented on one side by two electrodes. Depending on the desired direction of motion, the left or right electrode of the piezoceramic plate is excited to produce high-frequency eigenmode oscillations of hundreds of kilohertz. PILine® motors are vacuum compatible, non-magnetic and self-locking.
